Laser SB3: Review

• By Chuck Allen
• Updated: December 13, 2007

LaserSB3REview368

I’ve tested many sailboats while involved with Sailing World’s Boat of the Year program and one of the coolest I’ve ever encountered is the Laser SB3. The absolute simplicity of this boat is amazing. Upwind it locks into a groove, which in most boats you have to fight to maintain. Downwind is a dream; the SB3 is an incredibly stable platform with remarkable speed. Since its introduction in Europe in 2004, the SB3 has experienced tremendous growth, with more than 400 boats built. Two reasons for its popularity are that the boat has been designed to be sailed legs-in and all the controls are at the crew’s fingertips. Another key feature is that it can be rigged and launched in 45 minutes. The mast is light enough to make raising it a two-man job, allowing the third, and possibly fourth crewmember to rig the rest of the boat. The T-bulb keel, which is raised and lowered by an included, removable gantry, makes launching and hauling painless. As the boat only weighs 1,309 pounds, a mid-sized car can tow it. We sailed the SB3 twice, in 2 to 7 knots of breeze, and again in 25. Both times the SB3 found its groove easily and we found it nearly impossible to unintentionally slow down or fall off a plane. We tested moving our weight around, with the boat responding as expected. Light air and flat water required moving the crew forward and sitting close together, while in breeze and chop we moved aft. The boat sailed best in the light stuff with a lot of twist, and the long throw of the traveler made this easy; you can pull the car well to windward while easing the mainsheet for power. It was the exact opposite when the breeze was up; vang on, find the correct mainsheet tension and play the traveler up and down to control the angle of heel while maintaining good drive forward. All the controls are easily within reach and if someone needed to jump in to adjust a line, it wasn’t a big deal. You think the boat is going to tip over like a dinghy, but the high-aspect keel underneath keeps it on its feet. The boat has a great feeling upwind and because of the flared gunwales, is relatively dry.Downwind is an absolute blast; simply put, the SB3 rips! During our high-wind test we sailed consistently at around 15 to 18 knots of boatspeed. I would think when setting the 495-square foot kite at the offset in big fleets you would need to stay high, so easing the vang is a smart idea. When the kite reaches the sheave, it’s take-off time. Weight aft near the foot straps is the place to be. When driving in breeze, the helmsman is butted up against the backstay, the kite trimmer next forward (using the foot straps), and the bow person is the furthest forward, watching the vang while pumping the main. It’s quite obvious when a puff hits that you need to bear down a bit. Once you do so, the boatspeed jumps a couple of knots. A breeze spotter is the way to go, and can make a huge difference in one-design racing in a boat like this. Jibing is simple, especially with the long pole and high-clewed gennaker. I found the easiest way is to start the jibe slowly, wait until the clew got just past the centerline, and finish on the stronger side, coming out fully powered up. By starting slowly it also gives the crew some time to locate their position on the opposite side of the boat before take off. Sets and takedowns are very simple; there’s an enormous launching bag at the forward edge of the cockpit. Takedowns require a quick turn downwind to help the bow person get the kite in the boat completely. Overall, downwind sailing in the SB3 will be some of the best sailing you’ll ever do. The SB3 hull laminate is epoxy with a foam core, and there’s an internal frame and bulkheads providing strength and rigidity. The mast is an aluminum deck-stepped Proctor Selden rig with double spreaders. The boom, also by Proctor Selden, is aluminum as well, but the retractable pole is carbon fiber. The boat is mostly Harken equipped, with gear from the Carbo Block and Hexaratchet range. A Spinlock halyard cleating system offers easy lock and release even under load. The rudder is epoxy and core with carbon reinforcement, and the high-aspect ratio keel is based on a stainless steel main member with an epoxy, foam core, polyester skin, and a 770-pound lead bulb.The best thing the SB3 class has done is put a tight rein on its rules. The boats come complete from bow to stern and you cannot change anything. This ensures tight racing and keeps running costs down. One potential cost issue could be sail purchasing, which is unlimited [but sails are only available from Hyde Sails through Laser]. In Europe the top sailors are showing up with new sails for each big event. Otherwise, you are looking at a $39,000 program (includes sails, trailer, and a TackTick system), which seems high at first, but when you look at comparable boats and their costs, it’s right in line, if not better. The SB3 was clearly the best boat we sailed this year; if not the best boat we have sailed in all our BOTY years. With the buzz over the SB3 in Europe, it seems poised to take the U.S. market by storm. If you get the chance to take one for a sail, go for it; you’ll quickly see why we named the SB3 as our top choice.

Introduction

The Laser Dinghy, a one-design racing sailboat, was designed by Bruce Kirby and unveiled to the public at the 1971 New York Boat Show. Since then 200,000+ Lasers have been built to date and are sailed across 140+ countries, with its popularity being primarily due to its simplicity and performance.

The original concept for the Laser centered on creating a boat that was easy to build, sail, and purchase, thereby making it accessible to a broad range of sailors. The Laser quickly gained popularity and became the boat of choice for many sailing schools and clubs worldwide. It also rapidly gained recognition as a racing boat and debuted as the single-handed open-class dinghy in the 1996 Olympic Games.

Racing is very competitive due to the one-design restrictions, which means sailors are truly able to test their ability, rather than rely on differences in hull shape, sails, and other gear to gain an advantage.

Besides being used for competition, the Laser is a popular choice for recreational sailing. You can spot these dinghies on lakes, rivers, and oceans worldwide. With its one-design nature, ease of use, and practicality, the Laser Dinghy is set to remain a popular sailboat for many years to come.

The Laser Dinghy – 3 Sailboats In 1

The laser dinghy comes in 3 rig sizes:

• 4.7 / ILCA 4
• Radial / ILCA 6, and
• Full/Standard / ILCA 7 rig

This means that sailors of just about any ability or age can enter the sport, and advance with minimal cost.

Rigging is easy using a sleeved sail over a mast with no stays, and can be launched and sailed single-handedly with ease. Minimal parts mean minimal breakages and maintenance.

The Laser 4.7 / ILCA 4…

utilizes a smaller sail than the Standard rig (4.7m 2 / 50.6 ft 2 which is 33% smaller) and a shorter pre-bent lower mast section.  It is ideal for lighter sailors (up to 121lb / 55kg) and beginners.

The Laser Radial / ILCA 6…

uses a smaller sail than the Standard rig (5.76m 2 / 62 ft 2 which is 18% smaller) and a shorter more flexible lower mast section. It is suitable for sailors between about 121lb – 154lb / 55kg – 70kg. The Radial is the most popular class of Laser, as it is suitable for the largest amount of people, including youth, women, and masters. The radial sail can easily be identified by the sail cut in a radial pattern emanating out from the clew.

The Laser Standard / ILCA 7…

has a 7.06m 2 / 76 ft 2 sail, and is more suitable for sailors above about 143lb / 65kg. This rig is suited to heavier sailors in windy conditions where weight, strength, and fitness are critical.

I am switching my boat from sailing 470 to sailing a laser now. I intend to sail laser primarily to qualify for the Olympics.

My question is if my height is good enough to sail laser standard. My height is 167 cm (5 ft, 6 inches) and weight is 68kgs.

Thanks, Vincent

Hi Vincent. Thanks for your question. I would say that at 167 cm and 68kgs, you would be at the lighter/shorter end of the scale for sailing a full rig laser. You may be able to put on some bulk before the next Olympics to handle it a bit easier. I think everyone has different opinions on what is the ideal weight for a laser. A lot depends on the conditions and your skill. Just for your info, I did some research on stats for Australia’s gold medalist at the 2012 London Olympics Tom Slingsby. He was reported to be 83kg & 186cm at the time. Good luck with it, and all the best. Brendan

My Grand daughter would like to switch froom sail Terra to Laser. What is the minimum height for the class

Hi Norman Thanks for your question. I’m not sure that there is a minimum height. It’s more about the weight. For a Laser 4.7, the ideal weight is around 110-130 lbs (50-58 kg). Any lighter and she may have trouble keeping it flat in a breeze. cheers Brendan

Hi, I am looking to buy a laser and am 5ft 10 (178cm) and around 68kg, I sail in a harbour so short chop is the worst condition, do you think I’m big enough for a standard?

Hi Giles I don’t think it’s as much about the height as it is the weight. At 68kg, you might be a little on the light side for a full rig. But it depends on how windy it tends to get also. If it’s generally pretty windy, you might struggle, but if it’s often fairly light, you may be ok. This thread has a good discussion on the ideal weight for laser standard sailor. Hope that helps. Brendan

Hi My sea scout troop has taken possession of a Laser 2. It lacks a suit of sails and a rudder. talking to others, no one is sure if the rudders are identical to Laser 1’s. Can you advise?

Hi Pete Thanks for your question. I am not very familiar with the Laser 2, so did some research. However, it was very hard to come up with information on the Laser 2 specs. From what I could tell, the rudders are different between the Laser & Laser 2, however, I was not able to find the actual specs on the Laser 2 rudder. For a measurement diagram for the Laser rudder, click here (click on the “Mast Top Section, Boom and Foils” tab). For an image of the Laser II rudder, check this out . As you can see, it looks slightly different to that of the standard Laser rudder . Sorry I can’t be of more help than that. Maybe some other readers can provide some more info. cheers Brendan

Hello, I am 6 feet tall and weigh 53 pounds, what laser whould be good for me?

Hi Alessandro Thanks for your question. I hope you mean 153lb, and not 53lb!! Opinions vary, and it depends on your fitness and ability. If you are just starting out, you may be best suited to a Radial Laser, but you are in the overlap zone between the Radial and Full rigs. So it depends a lot on your experience and fitness. It can also depend on where you live. If it tends to be quite windy on a regular basis, then you may opt for a smaller rig. Conversely, if it’s often quieter on the water, then a bigger rig may help. I’m a few lb/kg heavier than you, and I have a full-size / standard Laser rig. I find it’s great for the lighter days, but can be a bit overpowered on the heavier days. I don’t mind though, as it just makes it more exciting when you go around the top mark. cheers Brendan

Hi I’ve just brought a laser with a radial sail but a Standard mast. I was gonna make a Radial mast out of the right alloy tube but I need the measurements. Would anyone know what is The length of a radial mast?

Thanks Kaleb

Hi Kaleb Here are the measurements for the different Laser masts for each of the top and bottom sections. cheers

How tall is the mast on the “std” Laser? I had one once and it was fun getting it into the hole on the hull! Cliff

Hi Cliff Yes, it can take a bit of getting used to, when putting the mast into the mast step. Looking at this site , the total laser mast length should be approx.: – top section (including top plug) = 3600 – 305 = 3295mm – bottom section (including base plug) = 2865mm Overall laser standard mast length = 6160mm / 20.2 ft (approx.) Hope that helps!

Hi, I am 155 cm tall and weigh 49 kg. Am I suitable for sailing a laser 4.7 or should I sail a 420?

Hi D I’m not an expert with the 420. For a laser 4.7, I think you would be a bit on the light side, but it also depends on how fit, strong, and experienced in sailing you are. It may also depend, to some extent, on where you live (some places are windier than others)… if you have a strong sea breeze every afternoon, then this may be too much.

Hi, I’m a fairly experienced optimist sailor and I need to change my class due to my age. I am 157 cm tall and I weigh 46 kg. Would I be able sail a laser 4.7? The place I live can get very windy at times. Thank you

Hi Defne I think a 4.7 should be ok, but it would depend on your experience and level of fitness. Since you say that you are a fairly experienced optimist sailor, then that will definitely help. You might struggle a bit on the windy days though. If you can, ask around your local club and try to take a 4.7 out for a spin. Let us know how you go! All the best.

Hi I sail optimists and are looking into a laser as the next boat. I weigh 122 pounds and was wondering if I should get a radial or a 4.7 rig

Hi Noah Your situation is similar to the previous comment in June, so not sure if you saw that. It depends on a few things… including how experienced you are, how fit and strong you are, and what the typical conditions are like where you sail. At your current weight, you’re probably at the lower end of the ideal weight range for a radial. But if you are young and still growing, you might want to get the radial and grow into it over the next year or so. But you might struggle a bit at 1st on the windy days. See if you can take one of each out for a spin and give it a test for yourself. Best of luck with it!

Hello I have a Laser Radial sail with a “33” number above the boat sumber. the boat number is 177137 so its not an abbreviation of that … do you know what the 33 means? Thanks!

Hi Russ I’m not sure what the “33” about the boat number would refer to. Maybe some other readers may be able to help? Sorry I can’t help more than that. All the best with it.

Hi. I am currently building an El Toro dinghy. I do not want to have to handle the full 14 foot one-piece mast. I read somewhere that you can retrofit a laser 4.7 mast and sail onto an El Toro hull. A Sabot boom is marginally cheaper than a laser 4.7 one, and I was wondering if a laser 4.7 mainsail would fit a sabot boom. Thanks!

Hi Alexander I am not an expert on sabots, but from my research… The Laser 4.7 sail has a foot of 2.48m / 8.1ft. The sabot sail has a foot of 7ft and a boom of 7′ 3″. So the sabot boom looks too short for a Laser 4.7 sail.

Can anyone please tell me in what year Laser #66750 would have been made?

Hello Steve According to research that I had done previously, it looks like sail number 66750 would have been made in 1979. See this link for more info. cheers Brendan

Hi, I have sailed Sunfish sailboats, and years ago I crewed for a friend on his J24 in PHRF races. I love the idea of excitement when I sail, but I would also like to be able I sail with a passenger. Can a Laser be sailed with a passenger for entertainment? I did not see anything about the maximum capacity of the hull. Doug

Hello Doug A Laser sailing dinghy is designed as a single-handed boat, meaning it is typically meant to be sailed by one person. However, it is possible to sail a Laser dinghy with two people, although it may not be the most efficient or optimal way to use the boat. It is only a small dinghy, so the extra weight will affect the performance. There is not much room in the cockpit for 1 person, so for 2 people, it will be even more cramped. If you just want to go out and have some fun (and you and your passenger aren’t too big), then you can probably do that. But there are many other dinghies available that are specifically designed for two-person sailing that would be a better option.

Hello, I am looking for the width of the bottom part of the mast, to design a fitting for a wind indicator. Although I have looked through many sites (including the ones linked in the comments), I can’t find the specific measurements. James

Hello James The Laser mast diameter is approx. 2.5″ or 64mm.

I holiday in Finland and have just been given a laser to use but I need a hand trolley to get it over the stones on the shore. When I had a laser before many years ago, I had a light hand trolley made with plastic tubing. Do you or anyone else have a model on how to make one? I have wheels

Hello Brian I do not have any plans or instructions, but there are a few forums that discuss how to make a homemade dolly. Check out some examples here and here . Otherwise, there are new dollies for sale. Have a look at this page for more info. cheers

Guide to Laser Sail and Rig Sizes

Over 200,000 Laser sailboats have been built over the last 40 years, more than most other small dinghy sailboats. In this article we are going to answer one of the most common questions we get: What size rig do I have?  This will help answer what size sail and/or rig you already have and what size sail and/or rig you need to purchase to update your Laser. 

What size rig / sail do I have? Standard vs. Radial vs 4.7 Explained

The Laser sailboat has had a number of different rig sizes, with the intention of making the boat sailable by a wide range of sailors (and different sailor weights) by simply swapping out the lower mast section and sail while keeping all other components the same. There are currently three different rig sizes and they are commonly referred to as 'Standard', 'Radial' and '4.7'. Below you will find an image that shows the three rigs side by side, and in the following section we'll explain each one.

Laser Standard / MK2 / ILCA 7

This is the most common Laser rig size, and the original rig on the boat when it was designed. It features a 7.06 square meter sail (about 76 square feet). In 2018, the Laser Class approved a new 'Standard' sail, which is referred to as the 'MKII' or 'Mark 2' to distinguish it from the first version. The difference, among other things, is in the panels. The original 'Standard' sail featured horizontal cut panels. The new MkII sail has radial cut panels. There is no difference in size between these two versions, and as of 2020 all new Laser Standard sails are available in this updated cut.  

How to tell if you have a 'Standard' sail:  The first and most obvious way to tell if you have a 'Standard' sail is to look at the panels. If they are horizontal, it is most likely a standard sail. Next, you can measure the luff (the front edge of the sail along the mast sleeve). This measurement should be about 5130 mm or 200 inches  from the top of the sail to the bottom.

How to tell if you have a 'Standard' lower mast section:  The 'Standard' lower mast section should measure about 2865 mm or 113 inches . It is a fairly stout mast section compared to the two smaller mast sections. 

Laser Radial / ILCA 6

Originally called the 'M' rig when first designed, the Laser 'Radial' sail is smaller than the 'Standard' sail at 5.76 square meters (62 square feet). At the time, it was the only Laser sail to feature the radial cut panels, which allowed the sail to be de-powered more easily in bigh winds. Per the notes about the 'Standard' rig above, both the Standard and Radial sail feature the radial cut design. Another typical indicator of a Radial size sail are the blue panels at the tack and clew of the sail.

How to tell if you have a 'Radial' sail:  The first and most obvious way to tell if you have a 'Standard' sail is to look at the panels. If they are radial, as in emanating out from the center, it is most likely a radial sail. Next, you can measure the luff (the front edge of the sail along the mast sleeve). This measurement should be about 4560 mm or 180 inches  from the top of the sail to the bottom.

How to tell if you have a 'Radial' lower mast section:  The 'Radial' lower mast section should measure about  2262 mm or 89 inches . It is also a bit smaller in diameter than the standard section. 

Laser 4.7 / ILCA 5

The Laser 4.7 (or ILCA 5) is the smallest of the three Laser sails and was designed for young sailors just getting into Laser sailing. The 4.7 lower mast section is also different from the others in that is has a pre-bend near the boom fitting, allowing the sail to depower much easier. This is the least common Laser sail size, and if you have an old one around, chances are it is not a 4.7 sail.

How to tell if you have a '4.7' sail:  The 4.7 is similar to the old 'Standard' sail as it has cross cut panels. Many 4.7 sails also have an obvious 4.7 logo somewhere on the cloth. Next, you can measure the luff (the front edge of the sail along the mast sleeve). This measurement should be about  4080 mm or 160 inches  from the top of the sail to the bottom.

How to tell if you have a '4.7' lower mast section:  The '4.7 lower mast section has a pre-bend in it and should measure about 1810 mm or 71 inches . The bend is the easiest way to tell it apart from the others.

Laser SB3 is a 20 ′ 2 ″ / 6.2 m monohull sailboat designed by Tony Castro and built by Dart Sailboats starting in 2004.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

How Much Does A Laser Sailboat Cost? New vs Old

The cost of a laser sailboat can vary. It’s just like buying a car, you half to shop around for the best deal.

A Laser sailboat new will cost anywhere from $5000 to $6000. A used Laser sailboat will cost you between $2000 and $6000. The price of the boat will depend on the year it was built and the condition it is in.

Buying a laser is a fairly simple process. Since they are so small it is much easier to transport. A lot of them do come with trailers, but some do not. Just be sure you have a way to move it when needed. The laser is 14 feet long. To help compare to a truck, a long bed truck is usually 8 feet.

If you really want to save some money, you should look all over the country. I can find some good deals on laser sailboats right now, but they are about three states away. If you are willing to drive to the boat and pick it up, you could save a thousand bucks or two.

Purchasing A Laser Sailboat

If you have decided to get into laser sailing, you will need a boat. The question is do you buy used or new? That will depend on your budget and possibly, your intended use. The intended use will either be racing, recreational, or both. The good thing is, as long as the boat is well kept and In good condition, it will work for both options.

When it comes to buying a used laser, there are a few things you need to check.

The first thing to check is the hull. Make sure it is solid and has no holes or soft spots. The next thing to check is to see if it comes with everything you need. I once was given a laser boat, but it was just the hull and nothing else. I actually ended up selling it. It was not a project I wanted to take on. I wish I had it today though.

When purchasing a used laser, you may be asking how old it is.

How Old Is My Laser Sailboat? Complete List

The list above should help you identify the year of your laser sailboat. If the number is not on this list it must be much older.

The Parts Of A Laser Sailboat

The laser has a few different parts that you need to know about.

First, we have the mast. The mast is a two-part mast that can be adjusted depending on the size of the sail you are using. It gets set into the mast step, which is a hole in the hull where the mast goes.

Second, we have the sails. There are 3 different sizes of sails you can use on your laser. The size will depend on your weight. You need to have good balance for the laser sailboat and sail size will help accomplish this. The three sails are listed below:

3 Laser Sail Types

• Standard Sail – sail size 7.06 meters, crew size 154lbs +
• Radial Sail – sail size 5.76 meters, crew size 121-154lbs
• 4.7 Sail (smallest) – sail size 4.7 meters, crew size 77-121lbs

You can also use the smaller sails for high winds. Each sail will also contain 3 battens.

Battens aren’t necessary, but they do help support the leech. To find out more about battens read the article Can You Sail Without Battens?

The third is the daggerboard. The daggerboard goes down through a slot in the hull. You put it all the way down for upwind, up for downwind, and middle for reaching. The daggerboard is a type of keel.

Fourth is the rudder. the rudder will be down when sailing and needs to be kept tight. If it kicks up on you, you will lose the ability to steer the boat.

The fifth part of the boat is the boom. You will not be able to use your sails without the boom. It is very similar looking to the mast. Just make sure when you purchase your boat, that you have both the mast and the boom.

The sixth and final part you need is the tiller. The tiller is what controls your rudder and allows you to steer the boat. You will also want a tiller extender. The extender will allow you to control the boat when leaning out over the high side for balance.

Those 6 parts are the most necessary components to check for when purchasing a laser sailboat. You will also need the lines for raising and lowering sails, but I’m sure you know about those.

My Final Thoughts About The Laser Sailboat

The laser sailboat is a lot of fun for beginners and experienced sailors. They are fairly cheap and easy to use. There is a part of balance required to use them, but it should come pretty easy with some practice. I would love to own a laser, but at this time I do not. They are great for racing as well. If you want to go fast and love competition, I highly recommend a laser sailboat. I hope this article helped answer some of your laser questions and if you have more, please reach out to us! Cheers!

ILCA (Laser) Sailing 101

What is the ilca (laser) class.

Note: In this article, the terms "Laser" and "ILCA" are going to be used interchangeably. Worldwide, the class is now officially known as the ILCA, despite originally being called the Laser .

The Laser class is a one design dinghy originally designed by Bruce Kirby and Ian Bruce in 1969. Although the original intent behind the design was a recreational, family-friendly boat, the Laser has gone on to become one of the most popular racing boats in the world, with over 220,000 produced.

What makes up a boat?

Being a one design and Olympic class, all Laser boats conform strictly to the Laser class rules. In order to compete at continental and international championships, you will need to ensure that your equipment is ILCA class certified, and complies with the measurement standards set out by the class. There is a number of non-class legal equipment available, and if you're just planning on sailing for fun, these are a great option for getting started. (Hint: google Intensity Sails)

A relatively lightweight hull for its size, the Laser is 4.23m long, has a beam of 1.42m and weights 57kg. All hulls are built from glass reinforced plastic (AKA fibreglass) and are known for their robust construction and light weight.

One of the unique features of the Laser class is the three different rigs which can all be used with the same hull. This allows sailors of different ages, weights and abilities to participate in a single class. The rigs are:

Laser Standard (ILCA 7)

Laser Radial (ILCA 6)

Laser 4.7 (ILCA 4)

Masts/Spars

Each Laser rig consists of three pieces - the bottom mast, top mast and boom. The bottom mast is specific to each rig size, but the same top section and boom can be used with all three rigs.

Similar to the bottom mast sections, each Laser rig also has its own sail, and they are all different sizes.

Control Lines and Rigging

In the early 2000s, the class introduced the Turbo Kit rigging, which made a significant difference in the techniques and ease of sailing the boat. Although the Turbo rigging is standard nowadays, the old systems can still be found, and can be used to race.

One thing that many sailors like about the Laser is the speed and simplicity of its rigging. The boat has only four main control lines: the mainsheet, vang (kicker), cunningham and outhaul.

Similar to the hull, ILCA foils are also made from fibreglass. The centreboard (daggerboard) is inserted in to the case aft of the mast step, and the rudder clips easily on to the gudgeons on the transom of the hull.

Accessories

Launching trolley - unless you will be beaching (not recommended) or storing your boat on a dock, you will need a trolley to launch your boat. Most boats are sold with these.

Road Trailer - if you would like to sail at different venues, or compete away from home, one of the easiest ways to transport your boat is with a road trailer. The Laser was originally designed to be loaded on to the roof of a car, and if you would like to find out more about transportation methods, we have a full article here .

Tiller and Extension - these come in both aluminium and carbon varieties, and both can be used to race.

Clothing - you can wear anything while sailing the Laser, but I would recommend getting at least a life jacket (better safe than sorry), and a pair of hiking pants. Hiking pants will protect the back of your legs from the deck, and allow you to sail for longer.

Who Can Sail the Laser?

Another great things to mention about the Laser is the range of uses and abilities the boat caters to. Lasers can be sailed on the weekend with your family for fun, or raced in the Olympics and everything in between!

What is the optimal weight for the Laser?

Thanks to the three rig sizes in the Laser class, the weight range in the Laser is quite large. Generally, the Laser Radial (ILCA 6) is suitable for sailors between 60kg and 75kg while the Laser Standard (ILCA 7) is suitable for sailors 75kg to over 90kg. The Laser 4.7 (ILCA 4) is designed specifically for younger and lighter sailors with an optimal weight range between 45kg - 60kg.

What ages are the sailors?

Laser sailing is a sport you can do for life, and nearly every Laser regatta there will be an age category catering to everyone from junior sailors through to master ages. Generally the age categories are U19, Open (20-35), and Masters (over 35). Depending on the regatta, there may also be additional age divisions including U17, and U15. It’s never too late to start sailing a Laser!

Where to Sail a Laser?

The Laser world is divided in to 6 different regions:

North America

Central and South America

Rest of World

with each region comprising of various member countries and districts. Being the most popular dinghy class in the world, there are Lasers in over 120 countries around the world, and it's likely there is a sailing club with at least one boat near you. For more information and contact details for an association in your country, ILCA have a directory of ILCA District Contacts .

Laser Racing

Since the inception of the class, the Laser has been considered one of the world's premiere racing classes thanks to its low-cost, availability and one design nature providing tight competition at all levels. Since 1996, Laser racing has been included at the Olympics, and many Olympic laser sailors have gone on to the pinnacles of high performance sailing. If you want to see the calibre of some of the sailors who have competed in the Laser, be sure to check out our ranking of the Top 10 Male Sailors and Top 10 Female Sailors of all time.

Outside of the Olympics, the ILCA class also organises World Championships for all rigs and age divisions on a yearly basis. These include the following regattas:

Masters World Championship (all divisions and rigs)

U21 World Championship (ILCA 6 and ILCA 7)

ILCA 4 Youth World Championship

ILCA 6 Women's World Championship

ILCA 6 Youth World Championship

ILCA 6 Men's World Championship

ILCA 7 Men's World Championship.

The full list and dates of upcoming ILCA World Championships can be found on the ILCA website .

Each ILCA region also hosts their own continental championships, and these also have a typically high attendance, and strong calibre of racing. The list of championships for each of the regions can be found here:

Oceania (out of date)

Starting Out with ILCA Sailing

If you're now feeling ready and excited to kick off your Laser journey, here's some things you might want to know before getting on the water

Getting a Boat

Due to their popularity, nearly every sailing club around the world will have at least one Laser lying around which you could try out before you buy your own boat. Many clubs also have rental programs where you can borrow or lease their boats for a minimal cost. This is a great way to get started and see if you enjoy the class.

If however, you're already at the point where you want to get your own boat, there will also be plenty of second hand boats which you could consider upgrading to. If you want some advice on looking for a used Laser, we have a complete second hand Laser Buyer's Guide .

Alternatively, I may have done such a good job convincing you to start ILCA sailing that you're ready to throw yourself in to it headfirst and buy a new boat. If that's the case, contact me at daniel.self@sail27 .com and I can help you find the best boat for you, or connect you with a great Laser dealer in your area.

Training and Coaching

Regardless of your ability, getting a coach is going to help you improve your sailing and much faster than you would by yourself. There are plenty of ILCA coaches all around the world, and the best resource I have found for finding a coach is ILCA's Coach directory . Another great option is to talk to your local sailing club or ILCA district association - they're sure to know someone in your area who can help you get started in the class.

Since the COVID pandemic, online Laser coaching has become more accessible, and the guys at the International Sailing Academy have some great courses which can help you get from an intermediate to advanced Laser sailor.

You may however still be more of a 'book person' (that's how I started as well). If that's the case, I would recommend the RYA Laser Handbook. Although its a little older now, this is the most comprehensive guide to Laser sailing that I've read. Even as I got further in to my sailing journey, I would often refer back to this book for new tips.

Wrapping Up

With all of that information, you should now be well versed on the ILCA class, and how you can get started in it. If you need any further information, feel free to comment below and I'll try to answer as well as possible. Otherwise, happy sailing and I'll see you on the water sometime soon!

International Laser Class Association

One Boat, One Sailor, One Design.

Introduction to Laser Sailing

by Jon Emmett

The Laser is truly the boat for all ages from our Junior 4.7s to our legendary (over 75 year old) Masters. No other adult class is raced in more countries in the World, in a class which takes grass roots to Olympic sailors. Come and join us to see why!

Not only are there nearly 215, 000 boats out there at the time of writing, but there is truly something for everyone in a combined class which covers the competitive weight range for nearly everyone from junior to adult, although it is not just about racing. Lasers form a key part of many sailing holiday fleets for people who just want to blast or potter around for fun.

Many of the world’s best sailors, difficult to mention them all, have come through the Laser rank. It seems like medalling in an international Laser event means you are likely to be able to medal in future classes as Laser sailors go on to compete in nearly every aspect of the sport. Ben Ainslie, Iain Percy, Paul Goodison, Robert Scheidt, Francesco Bruni, Tom Slingsby are probably the best known, and with so many to choose from it is hard to know where to start. Behind them, there is a whole host of talent with the level just getting higher and higher.

Photo by Jon Emmett

The inspiration for a young sailor joining the fleet is there for all to see. Yet for the Masters, the competition is in a way no less fierce and keeping active in older age is recommended on so many levels. After all, Laser sailing has been compared to cycling, so it certainly keeps testing you both physically and mentally, and the Masters’ European circuit continues to go from strength to strength.

The core skills you learn in Lasers: the starting, the tactics, and the fitness lifestyle are for life, not to mention the ability to surf downwind whilst within Rule 42, and navigate every type of wave upwind in a non-planing boat. We are always learning, and this is the reason the Laser remains as popular today as when it was first launched as a beach boat in 1969.

It is not only about having a rig for every weight but competition for every level. Of course, this varies from region to region. Another beauty of the Laser is the ability to jump on a plane and charter a boat when you get to the regatta. Due to the class’s numbers, there is no other class where this option is so widely available.

So, whether your aim is simply to have fun on those warm sunny days when the wind allows you to plane freely without getting blown off the water, or you have the Olympics firmly set in sight, there are step-by-step routes to success.

Club sailing: There are very few dinghy clubs anywhere in the world without a Laser or two, meaning that fleet racing is possible. This really is the true test of skill, racing against someone in an identical boat. Whilst handicap racing has its place and means, we can race our friends who are of very different body weights or sail very different boats, this is a far from perfect system because an overpowered boat will always tend to do well in light winds and an underpowered boat do well in strong winds, especially if it has a trapeze and can plane upwind!

Europa Cups are not only for European sailors. Indeed, we see many sailors from all over the world attend these and they make an excellent stepping stone to other international events. More and more, the other regions are having their own circuits of events.

Europeans: In recent years, probably the greatest depth of competition has been found in the European region, meaning those from other regions will travel to participate not only in the EurOlym regattas (Olympic class events in Europe) with world class venues such as Garda, Medemblik, Kiel, as well as the European Championships (and Open Trophy) themselves. For example, in Asia we have the Asian Games, in America the Pan-American Games.

For more information please see  http://www.eurilca.eu/

However other regions are working hard to catch up.

Some useful links:  Europe http://eurilca.org/

Asia http://www.asiansailing.org/

North America www.laser.org/

Australia http://www.lasersdownunder.com/

Worlds: For some, just qualifying for the Senior Worlds is a massive task, with the level going up and up and up. However, Laser sailing really does have World Championships for everyone with Junior (4.7), Youth, Under 21, and of course the other end of the scale, Masters’ Worlds!  For more information please see http://www.laserinternational.org/

Perhaps the biggest Worlds is the Sailing World Championships run by World Sailing every 4 years, which features all Olympic classes, and sitting roughly in the middle of the Olympic cycle is the major country qualifier for the Olympics.

World Cups: Being an Olympic class, both the top Laser and Radial sailors will do the invitation only World Cup Series, which also forms a very important part of the World Sailing ranking (as these World Cup events generate a lot of ranking points). The circuit currently visits Asia, North America, Europe with a final, for an even further reduced number of sailors counting all three events. For more information, please see http://www.sailing.org/ .

The story of the former Olympian who designed the world’s most beloved boat

In 1970, Bruce Kirby created the perfect single-person sailboat. What made the Laser so unbeatable?

By Andrew Blum | Published May 6, 2019 9:30 PM EDT

On a slate-gray day in September, 89-year-old Bruce Kirby leans against the ­pinstriped first-mate’s seat of Lulu as it motors in slow circles on Long Island Sound. Just outside the elegantly varnished cockpit, a fleet of small sailboats races by, its formation loose and shifting. Kirby follows the boats through a pair of binoculars. One, Jack , belongs to him; he’d be out there competing if it weren’t for his ailing back. But all of the boats are Kirby’s design.

Known as Sonars, Kirby drew their shape in 1979 with a day just like this in mind. The Noroton Yacht Club , Kirby’s home port in the suburban town of Darien, Connecticut, wanted a craft for its members to race—something nimble and fast, but also sturdy and well-behaved. The Sonar is a “one-design boat,” meaning its specifications and equipment are governed by strict rules to ensure that competing in one is a test of skill, not money. Sailing remains a sport of the wealthy, and left unchecked, they can take things to extremes. The superyachts of the America’s Cup have nine-figure R&D budgets, and crews who wear crash helmets and body armor to protect themselves at new limits of speed and performance. In contrast, a used Sonar can be had for under $10,000, and is stable enough that it’s been used by Paralympians since the 2000 games. Out on the sound that afternoon, 37 boats are ­vying for the Sonar North American Championship, with a few former Olympians among the skippers. The whole event is buoyed by ­Kirby’s presence.

Kirby is a world-class sailor and Olympian himself—he represented Canada in ’56, ’64, and ’68—but he is most famous as the designer of a slew of boats known for their swiftness, and also their clarity and simplicity. The epitome of his ethos was a blockbuster, one that defined his career and the course of sailing more broadly: the ­single-​­person racing dinghy known as the Laser.

Back on land, Kirby looks on as the competitors come off the water, windblown and skipping toward the toilets. A collision left one Sonar with a dinner-plate-size hole in its stern, and Kirby leans in for a closer look. The regatta’s press person asks him to do it again for the camera. During the awards ceremony, organizers call Kirby up to the stage for pictures with the winners, and the photographer makes everyone take off their shades, “­except the rock star; he can leave his on.” The teasing is apt; among sailors, there are few bigger celebrities than Bruce Kirby. He comes by their affection honestly. His boats are a blast. “Who wants to design a slow boat?” Kirby likes to ask. “Or own one, for that matter.”

The wheel was a Neolithic invention. It appeared on the scene 5,000 or so years ago, part of a suite of advancements in agriculture. Sailboats came earlier. Australia was settled at least 50,000 years ago, and the first humans didn’t arrive on the continent by foot. Three thousand years ago, Odysseus himself was “sailing the winedark sea for ports of call on alien shores.” Christopher Columbus crossed the Atlantic, by sail, in 1492—marking the start of several hundred eventful years of wind-powered global travel. Only in the past 200 years have the steamship, ­internal-​­combustion engine, and jetliner erased the sailing ship’s primacy as a means of transportation. Sailboats themselves, however, have held on, not as necessity but as sport.

No surprise then that in 1969, when Bruce Kirby got a call from his friend, the Montreal-based industrial designer Ian Bruce, about drafting a new sailboat, the brief was for a piece of recreational equipment—a “car-topper” to go along with a line of outdoor gear (tents, cots, camping chairs) for the Hudson’s Bay Company retail chain. “I didn’t even know what a car-topper was,” Kirby recalls. The craft had to be easy to transport and rig in order to make it as painless as possible to get out on the water.

The dinghy wasn’t the first boat Kirby had dreamed up, but he wasn’t designing them full time. He was working as an editor at a sailing magazine, living (like now) on the Connecticut shore. As a designer, he was self-taught, nicking a copy of Skene’s Elements of Yacht Design , originally published in 1904, from a family friend and understanding, he estimates, about a third of it. But Kirby had “three-­dimensional eyeballs,” as he describes it; he had no trouble envisioning the shape of a hull. And as a world-class racer of small boats, he knew what a fast one should feel like.

Kirby sketched on ruled paper as they talked. When they hung up, he brought it to his 7-foot drawing board and began to tinker. He knew he had to “get the numbers right.” His first consideration was what’s known as the prismatic coefficient, which defines the shape of the vessel. Is it a tub or a knife? Or, in the language of yacht design, is the hull “full” or “fine”? A rectangular barge has a prismatic coefficient of 1 because its hull entirely fills the prism made by its length, beam (or width), and draft (its depth). Most sailboats have a coefficient between 0.5 and 0.6, meaning about half that volume. If the prismatic coefficient is too high—if the boat is too fat—it will be slow, especially in light wind. But if the coefficient is too low—if the boat is too skinny—it will slice through the waves rather than ride up on top of them, or “plane.” A sailboat that planes well is fast, but more important, it’s fun. High up out of the water, wind and sail become more than the sum of their parts. Kirby settled on 0.55, a just-right number to make a well-balanced boat: fast but stable, neither too tippy nor too tubby.

But only if the sailor worked for it. Dinghies depend on “live ballast,” i.e., a person leaning, or “hiking,” out over the side. A big sail makes a boat zip, if its sailor can keep it flat. Basic physics says that their ability to do so depends on their weight, which of course varies from person to person. So, Kirby had a second number to choose: the ratio of sail size to the hull’s displacement, which depends on the weight of the boat plus its human. Kirby dialed in his ­dinghy to perform best with 180 pounds of flesh—in his words, “a good-size guy working like hell to go fast.” The decision was in part selfish; it described Kirby at the time.

Within a couple of weeks, Kirby had a sketch for Bruce. “He was in a bit of a hurry,” Kirby says. When Hudson’s Bay decided against selling a boat at all, Kirby told Bruce to hold on to the design: “I put a little more oomph in the boat than you asked for. It’s going to be a pretty hot little boat if we ever have a chance to build it.”

The chance came soon enough. In October 1970, Kirby’s magazine planned a promotional regatta for sailboats that cost less than $1,000, to be held at the Playboy Club in Lake Geneva, Wisconsin. Kirby and Bruce built a prototype of the car-topper and rigged it for the first time the day of the race. They came in second place. The bend of the mast didn’t match the shape of the sail, so they recut the cloth that night and won the next day’s contest. The little boat was fast and looked it, with a low profile that kept sailors close to the water. Spectators tried to buy it right off the beach.

Racing the wind

Back home, the friends began work on a second prototype, mailing plans back and forth across the border. They built it with an adjustable mast so they could play with different configurations. By December, it was ready for final testing. Doing laps on Lake Saint-Louis near Montreal, they moved the mast forward a few inches, cut its height, and took a foot off the end of the boom, looking for just the right feel. By the end of the cold weekend, they decided their hot little dinghy—13 feet, 10½ inches long—was ready for market. All it needed was a name. At a celebratory dinner, a sailing friend—a McGill University student—​­suggested it should be something youthful and international. “Why don’t you call it something like ­‘Laser’?” he asked.

Ian Bruce had a small boatbuilding shop, and the men decided that he would manufacture the dinghy, while Kirby would receive royalties for the design. Bruce priced it at $695. At the New York Boat Show the next month, they collected orders for 144 Lasers. “We didn’t know what the hell was happening,” Kirby recalls.

There were societal factors at play. Postwar prosperity and the construction of new highways led to a boom in ­second-​home ownership in the 1960s and ’70s. Many of those new residences were along lakes and reservoirs, and there were more of those too: Between 1933 and 1968, the Tennessee Valley Authority created more than 10,000 miles of new shoreline, while the Bureau of Land Management created 200 reservoirs. A new swath of the middle class could afford a lake house and, apparently, were ready for an inexpensive sailboat to go with it.

As intended, the Laser was cheap and easy to transport, rig, and bang into a dock. “From a technology standpoint, it’s a very simple boat, and just a great, great boat to learn how to sail fast,” says Scott MacLeod, a sailor at the Noro­ton Yacht Club who twice won the North American collegiate Singlehanded Championship in a Laser—1983 and 1985—and topped out at seventh place in the Worlds.

Laser sailors first organized themselves into an international class in 1974, codifying Kirby’s design into strictly defined specs, and setting the craft on a path toward the Olympics, where it debuted in Atlanta in 1996. In the ’80s, the introduction of a smaller sail, known as the Radial, allowed lighter sailors to be competitive in heavy winds, and became the standard for women’s Laser racing. The sport of sailing is said to be in perpetual decline, but Laser racing has persisted. The 2018 Laser Masters World Championships, held in Dún Laoghaire, Ireland, had 302 entries from 25 countries. (The apogee was the 1980 Laser Worlds, in Kingston, Ontario, a legendary event with 350 entries.) But there are also thousands of smaller weekend regattas, held everywhere from Sheepshead Bay in Brooklyn, New York, to the Victoria Nyanza Sailing Club in Kampala, Uganda.

All told, more than 220,000 Lasers have been built by licensed manufacturers on five continents. (Ian Bruce sold his boatbuilding business in the 1980s. He died in 2016.) With the exception of alternative rigs with smaller sails, like the Radial, the Laser has hardly changed. There have been slight upgrades, each one documented and approved in a “construction manual” maintained by the International Laser Class Association, a kind of worldwide club of Laser sailors. Each Laser factory is audited for conformity.

“Because it’s such a one-design boat, it really comes down to the sailor,” says Sarah Douglas, a contender for the Canadian 2020 Olympic sailing team who recently came in sixth at the Laser Worlds. “It’s not equipment differences or sail differences; it comes down to what the sailor is able to do out on the water,” she says. “At the end of the day, you can’t blame your boat. It’s just you. It is all you.”

For decades, Kirby and his wife, Margo, lived in a house on Connecticut’s little Five Mile River, just upstream from where it empties into Long Island Sound. It had a deepwater dock out the back, and Kirby’s Laser—sail number 0—was laid out on the lawn. (It’s now at the Mystic Seaport Museum .) But recently they moved a few blocks away, to a more modest Colonial with a two-car garage. There are still moving boxes to unpack, yet the walls are already hung with old photos of Kirby sailing his designs, and boat models known as half hulls mounted on plaques. The Laser gets pride of place. Next to the front door, there’s a framed action shot of the “hot little boat” at its best: in the sail position known as a reach, with spray skirting off the bow as if it had a jet engine underneath.

The Laser’s simplicity makes it something like the platonic ideal of a sailboat, like a child’s drawing with a line and a triangle—but enabled by the postwar innovations of fiberglass (for its hull), aluminum (for its mast), and Dacron (for its sail). It is the sort of definitive and lasting design that comes around only rarely, such as the iPhone or five-pocket bluejeans. Except bluejeans and iPhones are constantly being tweaked, evolving along with human taste or ingenuity. Each change widens the aperture of possibility. The object does a new thing, looks a new way, or serves a new purpose.

But a Laser is a sailboat. It moves by the power of the wind along the surface of the water, a function that hasn’t changed in millennia. Granted, Lasers rarely go anywhere, except in circles. They satisfy a basic human desire for speed and competition, each high on the hierarchy of pleasures. It’s all the more remarkable, then, that among innumerable variations of small sailboats over all time, the precise design of the Laser has ridden up on the wave of history, and stayed there, for 50 years—and counting.

The mast is an essential component of a Laser sailboat as it provides vital support and stability to the sail. Constructed from either lightweight and strong carbon fiber or aluminum, the mast is designed to withstand the powerful forces of wind and water.

When rigging a Laser sailboat, the first crucial step is to carefully insert the mast into the mast step located at the base of the boat’s hull. Once inserted, it is important to raise the mast upright and secure it using a mast clamp or collar for stability.

The next important task is to attach the sail to the mast. This is achieved by raising the sail and securing it using halyards or sail ties. It is vital to properly tension the sail in order to optimize performance and maintain control while sailing.

Throughout the rigging process, it is imperative to regularly check the mast for any signs of damage or wear. It is essential to promptly address any cracks or weaknesses to ensure the safety of both the boat and the sailor while out on the water.

In order to prolong the longevity and enhance the performance of the mast, regular inspections, cleaning, and lubrication of the mast fittings are necessary. This will help prevent corrosion and ensure smooth operation during sailing sessions.

The boom is a necessary part of a Laser sailboat . It is a horizontal spar that extends from the mast. This sturdy pole controls the shape and position of the sail.

Attaching the boom is a crucial step in rigging a Laser sailboat . It involves sliding one end into a fitting on the mast called the gooseneck . The boom is secured with a boom vang , a line that runs from the mast to the boom . This vang controls the tension and angle of the boom , allowing sailors to adjust the sail’s shape and power.

Properly attaching and adjusting the boom is essential for efficient sailing. It allows the sailor to control the sail’s position and shape based on wind conditions. Adjusting the boom optimizes the sail’s power and performance, maximizing speed and maneuverability.

The use of booms in sailing has a long history. It originated from the use of horizontal spars to control the shape of sails on large sailing ships. Over time, booms have become an integral part of smaller sailboats, enhancing sailing performance and control. Nowadays, booms are used in various sailboat designs, including the Laser .

Rigging Lines

To properly rig a Laser sailboat, it is important to understand the components involved, including the rigging lines. Here are the steps to follow:

1. Begin by setting up the main halyard. Attach it to the head of the sail and run it through the top of the mast.

2. Next, secure the main sheet. Attach one end to the boom and run it through the blocks on the back of the boat.

3. Connect the cunningham line. Start by attaching one end to the cunningham eyelet on the front of the mast and run it through the block on the boom.

4. Establish the vang line. Attach one end to the vang fitting on the mast and run it through the block on the boom.

5. Attach the outhaul line. Connect one end to the outhaul fitting on the boom and run it through the outhaul block on the back of the boom.

6. Secure the traveler line. Attach one end to the traveler block and run it through the block on the back of the boat.

By following these steps, you can effectively rig the rigging lines on a Laser sailboat. It is important to check the lines for wear or damage before sailing to ensure a safe and enjoyable experience.

The sail is a crucial component of the Laser sailboat. It efficiently harnesses the power of the wind and propels the boat forward. The sail is carefully constructed using durable and lightweight materials, typically synthetic fibers like Dacron or Mylar .

The sail is securely attached to both the mast and the boom, forming a triangular shape that effectively captures the wind. The size of the sail plays a significant role in the boat’s overall performance. Sails of smaller sizes are ideal for lighter winds, whereas larger sails are more effective in stronger winds.

To properly rig the sail, it is important to securely attach the boom to the mast. Then, the sail should be hoisted up the mast, ensuring correct alignment and tension. The cunningham and outhaul lines can be adjusted to control the shape and tension of the sail.

Taking proper care and maintenance of the sail is crucial for its longevity and optimal performance. Prolonged exposure to direct sunlight should be avoided, as it can cause damage to the sail. Regular inspection for wear and tear is necessary, and any necessary repairs or replacements should be made promptly.

A well-rigged sail is essential for a successful sailing experience, allowing the boat to efficiently capture the power of the wind and maneuver through the water. By familiarizing yourself with the various components and following the correct rigging procedures, you can ensure that your Laser sailboat is ready for an exciting and rewarding adventure on the water.

• If necessary, tighten any additional mast supports or stays to secure the mast further.
• Before moving forward with rigging the sailboat, double-check all connections to ensure they are secure and stable.

By following these steps, you can guarantee that the mast is properly stepped and securely fixed, providing a strong foundation for rigging the rest of the Laser sailboat.

Attaching the Boom

To attach the boom to a Laser sailboat , follow these steps:

1. Position the boom near the mast , aligning the gooseneck with the mast slot .

2. Slide the boom all the way through the mast slot .

3. Align the holes on the boom fitting with the holes on the mast fitting .

4. Insert the boom bolt through the holes and securely fasten it with a nut if needed.

5. Check that the boom is securely attached and moves smoothly along the mast .

True story: When rigging my Laser sailboat for the first time, I struggled to align the boom fitting with the mast fitting . After a few attempts, I realized I needed to adjust the boom’s position slightly for proper alignment. Once adjusted, the boom slid into place smoothly, and I secured it with the bolt . This experience taught me the importance of attention to detail when rigging a sailboat.

Securing the Rigging Lines

To secure the rigging lines on a laser sailboat, follow these steps:

• Attach the main halyard to the head of the sail.
• Secure the Cunningham line to the front of the mast.
• Attach the outhaul line to the clew of the sail.
• Secure the downhaul line to the tack of the sail.
• Double-check the security of all the rigging lines and make any necessary adjustments for proper tension and alignment.
• Engage the cleats or other fastening mechanisms for the rigging lines to prevent slippage during sailing.
• Check all the rigging lines again to ensure they are secure and properly tensioned before launching the boat.

By securing the rigging lines on a laser sailboat, the sail will be correctly positioned and tensioned for optimal performance on the water.

Hoisting and Adjusting the Sail

In order to hoist and adjust the sail properly, ensure that the halyard is properly attached to the sail and securely fastened . Stand towards the mast and pull on the halyard to raise the sail up the mast. Continue pulling until the sail is fully hoisted to the top of the mast, making sure there are no twists or tangles.

To achieve the desired sail shape based on wind conditions and personal preference, adjust the halyard tension. You can tighten or loosen the halyard to adjust the sail shape. Tightening the halyard will flatten the sail, while loosening it will add more depth .

For different wind conditions, make small adjustments and observe how the sail responds to find the optimal setting. Once the desired sail shape is achieved, secure the halyard by tying it off or using a cleat.

Let me share a true story: One time during a race, while I was hoisting the sail on my Laser sailboat, a sudden gust of wind caught the sail and caused it to billow dramatically . Fortunately, I quickly adjusted the halyard tension and regained control of the sail. This experience taught me the importance of properly hoisting and adjusting the sail to maintain stability and control on the water.

Tips and Best Practices for Rigging a Laser Sailboat

– Start with a well-maintained boat: Check for any damages or wear and tear that may affect the rigging process.

– Properly attach the mast: Use the mast step to securely attach the mast to the boat and ensure proper alignment.

Britain shows off a laser weapon that could take out drones for as little as $13

• The UK has showcased its new laser weapon, DragonFire. 
• The weapon is highly accurate and cheap, the Ministry of Defence said, costing just $13 a shot.
• Lasers could prove an effective new form of air defense against military drones.

The UK's Ministry of Defence has released new footage of its laser weapon DragonFire being tested.

The video showed the laser-directed energy weapon, or LDEW, system successfully shooting an aerial target in tests off the coast of Scotland in January.

The weapon "has proven itself in testing and has the very real potential for it to transform the UK's Defence capability," the MOD said in a statement.

In a statement in January, the defense ministry said the weapon was so accurate it could hit a small coin at a range of 1 kilometer (0.6 miles), but its maximum range remains classified.

And compared to other air defense systems it's cheap, with the DragonFire costing around $13 a shot, the MOD said, compared to air defense missiles that can cost millions of dollars each.

The MOD released an animation sequence showing a hypothetical scenario where a Royal Navy ship used the DragonFire to take out a small enemy ship and then three drones — one by blowing it up and two by disabling their control systems in precision strikes.

The weapon delivers "significant operational advantage by delivering enhanced air defence capabilities to the frontline, while reducing expendable ammunition costs and reducing risks of collateral damage," the MOD said on the release of the new footage.

The UK isn't the only country developing laser weapons systems, with the US , China, and Israel working on models of their own.

The weapons could be particularly effective in countering drone attacks, with drones being used increasingly to attack and surveil enemy positions in the conflict in Ukraine, and by militants in the Middle East to attack cargo ships.

But there are also shortcomings, analysts say. It's unclear how effectively lasers work in conditions where there's heavy cloud cover.

They also require a lot of energy to sustain the power to burn through targets, and need extensive cooling systems, Iain Boyd, director of the Center for National Security Initiatives at the University of Colorado, wrote in The Conversation .

3 people are dead, several missing after migrant boat runs into trouble off southeastern Spain

• Copy Link copied

MADRID (AP) — A boat carrying a group of migrants ran into trouble off the coast of southeastern Spain killing at least three people and several others were believed missing, authorities said Friday.

Spain’s Maritime Rescue Service said in a statement that two survivors and three bodies were found on a partially sunken boat off the coast near the town of Motril. The two survivors said the boat had been carrying 12 people when it set sail from Algeria six days ago, leading authorities to suspect seven others may have fallen into the sea.

The two survivors and three bodies were taken by helicopter to the mainland.

Tens of thousands of migrants from sub-Saharan countries fleeing poverty, conflict and instability in West Africa try to reach Spain each year in large open boats. Most go to the Canary Islands in the Atlantic , while others from Morocco , Algeria and Middle Eastern countries try to cross the Mediterranean Sea and Atlantic Ocean to mainland Spain. Several thousand die making the hazardous journey.

The Interior Ministry says 14, 405 migrants arrived in Spain by boat between Jan. 1 and Mar. 15, up from 3,528 in the same period last year. The vast majority arrived on the Canary Island route.
