The Different Parts Of A Sailboat Explained

A sailboat consists of hundreds of parts, each with its specific term and function. From stern to bow, keel to mast, each part and its equipment plays a vital role in making the vessel seaworthy and able to sail.

In this guide, I’ll show you most of the components so you can better understand what they are and their function. We’ll begin with the main components, move to the basic features, and finish with our interior and equipment.

The main parts of a sailboat

The main parts of a sailboat are the key components that make it a vessel able to sail. You’ll notice that the structure has several distinct differences from powerboats.

We can categorize the main parts into the following:

• Hull: The main structure, or “body” part of a boat.
• Keel: The heavy fin at the bottom allows stability under sail.
• Rudder: The fin sticking down at the stern, allowing us to steer the vessel.
• Mast: The “spars” or “poles” holding the sails.
• Rigging: The standing rig is the wires that supports the mast. The running rigging is all the lines that control the sails.
• Boom: The horizontal spar supporting the bottom of the mainsail.
• Sails: The canvas used to harness the energy of the wind.

Let’s dig a bit deeper into each of the components.

Hull – The main structure

A sailboat’s hull is the vessel’s main body or structure. The shape is vital to the boat’s performance and stability, and you have probably seen boats in many different forms. Older vessels are typically narrow, with a rounded underbody and a small stern. Modern designs have a flatter belly and broad stern supporting dual helm stations.

One of the hull’s primary functions is to displace water and provide buoyancy to keep the boat afloat. The hull is also the structure that holds the vessel’s living compartments and all its equipment. The main structure must be strong enough to withstand the forces of the water and any rough weather conditions that Mother Nature might throw at it.

Fiberglass (GRP), steel, aluminum, and wood are the most commonly used hull materials, each with pros and cons.

You can learn more about hull materials and their strengths in this article .

A monohull is a type of sailboat that has a single hull. Monohulls are classified into two categories based on weight and shape: planing and displacement hulls.

Sailboats with more than one hull are called  multihulls.  There are two types of multihulls: catamarans, which have two, and trimarans, which have three. These boats are typically designed with planing hulls.

Keel – The fin under the boat

The keel of a sailboat is a structural fin that extends downward from the bottom of the hull. There are several types of keels, each with unique characteristics and advantages. They all serve the same fundamental purpose of stabilizing the boat when we sail by adding lateral resistance in the water and weight at the vessel’s bottom.

Standard keel designs include:

• Lifting Keel

Some sailboats have a retractable centerboard functioning as their keel, allowing them to take the boat into shallower areas.

Rudder – To steer the boat

The rudder is a flat surface that sits perpendicular to the waterline. It is connected to the boat by a pivot point, allowing it to swivel left and right. When the steering wheel or tiller is turned, the rudder moves, creating drag in the water causing the boat to turn. The size and shape of the rudder can vary depending on the size and type of boat.

The most commonly seen rudder designs:

• Full skeg-supported
• Semi skeg-supported

Skeg-supported rudders are structurally one of the most reliable and robust constructions, but they are less efficient than a balanced rudder performance-wise. Balanced rudders pivot around their vertical center, giving less drag in the water and higher maneuverability at the cost of being a more vulnerable construction.

Twin rudders are often seen on modern performance sailboats with a wide stern. When the sailboat  heel over , the leeward rudder gets better track through the water than a single rudder placed at the vessel’s center line. Contrary to some misconceptions, they can’t be controlled individually, even if the boat has two steering wheels.

Mast and Rigging – Supporting the sails

The mast is the long vertical spar that extends upward from the deck of a sailboat and holds the sails. It is the tallest part of the boat and is typically made of wood, aluminum, or carbon fiber. The mast is held in place by stays and shrouds, which form the sailboat’s  standing  rigging.

Depending on the rig the boat is manufactured with, there are several different types of masts. For example, a sloop-rigged sailboat will have only one main mast, while a ketch-rigged vessel will have a smaller additional mizzen mast placed further aft from the main mast.

There are two types of rigging:

• The Standing rigging   consists of the stays and shrouds that keep the mast or masts in place.
• The Running rigging   is the lines we use to hoist, lower, and control the sails.

Pro Tip: “S par” is a general term for a pole made of a solid material like wood, metal, or composite and is used to support a boat’s sail. The mast, boom, spreaders, and poles are defined as spars.

Boom – Supporting the mainsail

The boom is a horizontal beam extending from the mast and supporting the mainsail’s tack and clew (bottom two corners). It is attached to the mast by a hinge called a Gooseneck .

We use the boom to control the shape and angle of the mainsail to optimize its efficiency and power. Some booms also have a  Vang  or  Rod-Kicker  installed to assist in trimming the mainsail.

Sails – The canvas used to harness the energy of the wind

Most vessels have at least two sails, depending on the rig type and boat setup.

The Mainsail flies behind the mast, on top of the boom. Although it may not always be the largest sail on the vessel, we commonly refer to it as “the main.”

The Headsail(s ), located in front of the mast, are often of different sizes and shapes, and many sailboats have more than one. The Jib and Genoa are two of the most common types.

Different types of sails are used for various sail plans and situations, and you can learn more about them in this guide .

Now that we had a look at the main parts of the boat, let us dive deeper and look at the rest of the vessel.

The starboard and port side of the boat

Learning about the boat’s components is very important, but we must also know how to orient ourselves on the vessel. Using the words “left and right” on onboard often leads to confusion.

If you refer to something on the left side of the boat, the person facing you will be confused. He won’t know if you are referring to his or your left. This is where the terms “Port” and “ Starboard ” make better sense.

When facing the front of the boat or the  bow , your left side of the boat is the  port  side, and the right-hand side is the starboard . If you turn around and face the back of the boat or the  stern , your right-hand side will be the  port  side.

• A red light identifies the port side of a vessel.
• A green light identifies the starboard side of a vessel.

Windward and Leeward

• The windward side of the boat is the side facing the wind. If the wind comes from your right-hand side while facing forward, the starboard side is windward. This will be the boat’s high side as the wind heels the boat over.
• The leeward side of the boat is the side opposite to the wind. This will be the lower side of the ship while sailing as the wind heels the boat over.

Windward and leeward are two of the most important aspects to understand when sailing and navigating. Not only to identify equipment and gear on each side of the boat but to avoid collisions when sailing close to other vessels. There are rules on the water dictating which boat is “Stand On” and which has to “Give Way” depending on whether you are the windward or the leeward vessel in the situation.

Basic parts of a sailboat

The boat’s bow is the front part, typically shaped like a “V” to cut through the waves. Larger vessels often have a locker for their anchor chain in this section, holding the anchor at the front.

The midship section is the center of the boat. Some refer to this part as amidships.

The stern is the rear or back part of the boat. It is also referred to as the  aft . I’ve had French crew calling the stern the butt of the vessel, which is funny but also correct!

The beam is the widest part of the boat. Also referred to as the sides on the middle.

The transom is a flat surface across the stern of the boat.

The waterline is the part where the hull (body) of the boat meets the water. Many vessels have a painted stripe to mark the waterline, indicating how loaded the ship is. If you have too much stuff on board, the waterline goes underwater, and it is time to do some housekeeping!

The freeboard is the vertical part of the ship side between the water and the deck. When you see a blue boat like Ellidah, the freeboard is the blue part.

The deck is the “floor” of the boat when you are outside. You have probably heard the term “All hands on deck!” The  front deck  is the deck space in front of the mast.  Side decks  are the decks on the boat’s sides.

The  mid-deck  is between the cockpit and the mast. The aft deck is the deck behind the cockpit. Sailboats with aft cockpits often don’t have any aft decks, but some have a swimming platform instead.

The cockpit is the boat’s steering position and where you will find the helm.

The helm is the position the helmsman uses to steer the boat. Smaller sailboats often use a tiller to navigate, while most bigger yachts have one or two steering wheels.

Main parts below deck (inside the boat)

Let us look at the interior to highlight and learn about the parts we have below the deck.

The Companionway

The companionway is the “front door” of the boat. This is where the steps lead from the cockpit or deck down below. It is usually opened and closed using a hatch, two doors, or a plate.

The Galley 

The galley is the boat’s kitchen. This is where sailors prepare their delicious meals.

The Saloon 

The saloon is basically the boat’s living room, usually where you find the settee and dinette. This is where delicious meals from the galley are served together with refreshing beverages in good company.

The settee is the sofa or couch in a boat. It is also used as a sea berth to sleep in when sailing.

The dinette is the area where you can sit down at a table and eat your dinner. It’s also perfect for consuming rum and a game of cards in good company.

A cabin is often used as a bedroom in a boat but is not necessarily where you sleep. Many boats have more than one cabin.

A berth is a place in the boat where you can sleep. This doesn’t necessarily have to be a bed and can often include the sleeping space in the saloon. Sea-berth usually refers to a sleeping position where you are tucked well in and can sleep when the boat is heeling over and moving around.

The head is the toilet on a boat. If your skipper tells you to go and clean the head, getting out the shampoo won’t do you any good!

Nav station

The navigation station is usually a chart table and a console with mysterious instruments like radios, switchboards, and complicated electronics. This is where adventures are planned and the skipper’s favorite seat onboard.

The bilge is a space in the bottom of the hull where water collects and sometimes a storage space for all sorts of things. It usually contains a  bilge pump  to pump out water that finds its way into the boat in various places.

A v-berth is a bed in the front cabin shaped like a V.

A bulkhead is a wall inside the boat, usually supporting the structure.

Hardware and Equipment

Sailboats come equipped with a variety of different hardware and equipment. While the specific items may vary from boat to boat, there are some essentials that nearly every sailboat has.

A winch is a metal drum that gives you a mechanical advantage and is used to control and tighten lines. These can be operated by turning a line around it and pulling manually or by a winch handle to get more force.

Most modern winches are so-called “self-tailing,” which means they lock the line on so you can winch the line without holding on to it. Some boats even have electrical winches operated by a button.

A cleat is a fitting used to fasten a rope. Most boats have at least 6 of these. One on each side on the bow, midship and stern. These are used to secure the boat to a mooring buoy or key. Many ships have more cleats than this for various lines and ropes, and they can be used for anything as they are strong points fitted to the hull.

The sprayhood is the boat’s windshield that protects the people in the cockpit from sea spray. Some vessels have a canvas sprayhood that can be folded down or removed. Others have solid sprayhoods, often called a  hard dodger  or a  doghouse .

The bimini is the cockpit’s “roof.” It protects you from the elements and shelters you from spray, rain, and burning sun rays! A bimini can be made of canvas or hard material. A hard bimini can also be called a  hardtop .

Dinghy 

A dinghy is a little boat you use to get from the mothership to shore when you are at anchor, also called a  tender  or  annex . It can be everything from a small inflatable rubber kayak to a RIB or even a solid boat.

An essential and valuable piece of kit as it is the daily driver for most cruisers. It is like the car of a land crab, used for all commuting on the water and hauling important stuff like beer, rum, and food onboard. Dinghies often have electric or petrol engines, which we call outboards.

Dinghies are also great to use for watersports, such as wakeboarding!

Like Captain Ron said in the movie, fenders are the rubber bumper things you hang off your boat to prevent it from scratching against something like the pontoon or another ship. It is conveniently also used to sit on or as a backrest while relaxing on deck.

A boat hook is a long stick with a hook at the end. Used to grab lines, items, and stuff that is too far to reach by hand, like cushions flying overboard. It is also convenient as a tool to push the boat away from another craft or the key. Most vessels have them on board.

The guard rail can be a flexible wire or a solid metal rail surrounding the boat to prevent us from falling overboard. Some also use a net as an addition for increased safety.

The pushpit is a metal guard rail around the stern of the boat. This is where the guard rail is secured on the stern: a common place to mount the BBQ, life raft, and the outboard for the dinghy.

The pulpit is the metal guardrail on the bow. This is where the guard rail is secured onto the bow.

The stanchions are the metal bars that keep the guard rail in place around the boat between the pushpit and the pulpit.

An arch is a typical structure made of stainless steel on the back of a boat and is often used to mount a variety of items like antennas, radars, solar panels, wind generators, etc. It is also convenient to use for lifting the dinghy and its outboard.

Ground Tackle

The ground tackle consists of several things:

• Your anchor
• Your anchor  chain
• The  link between the two
• The connection between the chain and your boat

It includes all equipment holding your boat to the ground. Larger boats sometimes have two anchors on the bow.

A windlass is a winch that hoists and lowers the anchor and chain. Most boats have one on the bow and some on the stern. These incredible things can be electrical or manual (some are both) and are essential to anchor your boat when not in a port or marina.

VHF stands for “Very High-Frequency Radio.” It broadcasts on the VHF network and allows you to communicate with others around you. Sadly, you won’t be able to tune in to your favorite radio show on these.

Still, they are essential for contacting other boats and port authorities. It is also the radio you will transmit an emergency mayday over in case of emergency. VHF radios sometimes require a license, depending on the country you are in.

Chartplotter

A Chartplotter is a navigation computer that shows various information on a screen, like charts, routes, radar images, etc. It is another vital piece of equipment that helps you navigate and maneuver the boat.

Final words

I hope this guide has been helpful and not too overwhelming for you. We’ve covered many of the parts of a sailboat and its terms and functions, but this article only touches on the basics. If you want to keep learning about sailing, I have written several other guides to help you get started.

Now that you have a basic understanding of sailboats, it’s time to take the next step and dive into a sailboat’s standing rigging .

Illustrated Guide to Sailboat Parts [Updated 2023]

The lingo of sailing is baffling to many newcomers. While the actual sailing is pretty easy, it’s hard to wrap your mind around the bookwork when it seems like every little thing on a boat goes by its own nautical term. 

Here are a few names for parts of a sailboat that you might not have thought about before. For even more nautical word play, check out our complete guide to sailing terms .

Parts of Sailboat Hulls

The boat’s hull is its main body. Most are made of fiberglass, but there are a few aluminum sailboat models out there too. Wood is more traditional but more difficult to maintain than these modern alternatives. Sailboat hulls are displacement hulls, which means they sit low in the water and move relatively slowly. The hull’s job is to displace water, so you stay afloat!

Bow The forward “pointy end” of the boat.

Stern The rear end of the boat.

Transom If the stern of a boat has a flat section, it is called the transom. (I wrote about it in detail here: What Is the Transom on a Boat )

Canoe Stern or Double-Ender Some boats lack a transom; instead, their stern comes to a point like a bow. This is a “double ender” or a canoe stern.

Port and Starboard Sides Port is the left side, and starboard is the right side. 

Freeboard This is the height of the sides of the boat above the water.

Deck The upper portion of the boat that you walk on. 

Sheer Sheer is the curve of the deck when viewed from the side. Some boats have none, and some boats have a lot. 

Cabin Coach Roof Most sailboats have a raised coach roof on top of the cabin area.

Bottom of a Sailboat – Keels and Things

There are tons of parts on a sailboat that you only ever see if it’s out of the water. Boats are hauled out at boatyards by giant cranes, or a special machine called a travel lift . 

Keel The boat’s keel is the underwater feature that counters the effects of wind pressure on the sails. It keeps the boat from tipping over, but it also keeps the boat going in a straight line as it moves through the water. If a boat has no keel, the wind will push it downwind. 

A keel is heavy–it is weighted with thousands of pounds of ballast (usually lead). So when someone refers to a “keelboat,” they mean that it is a big boat with a weighted keel built for cruising. The built-in weight of a keel keeps the boat from capsizing. Also, the water flow over the curved surface of the keel helps the boat sail into the wind.

Smaller boats with centerboards or daggerboards are on the opposite end of the spectrum from keelboats. These aren’t weighted and could tip over (capsize) in the wrong conditions.

Types of Keels

Full Keel A classic and time-tested design, full keel boats are favorites among passage-making and ocean-crossing cruisers. They’re stable and comfortable at sea and very safe. However, they have a reputation for being slow compared to more modern designs.

Modified Full Keel The modification is a cut-away forefoot. That means it looks like a full keel, but there isn’t as much keel up near the bow. This reduces the underwater “wetted surface area” and makes the design a little bit faster while preserving the other good things about full keel designs.

Fin Keel The fin keel looks like a shark’s fin pointed downward. Some are narrow and very deep, while others are longer and shallow. Fin keels are bolted to the bottom of an otherwise flat-looking hull design. The fin has a foil shape that creates a lifting force as water flows over it. In addition to its ballasted weight, this opposes the sails and leeway. Most modern sailboats have some version of a fin keel.

Bulb Keel The ballast should be placed as low as possible to lower the boat’s center of gravity. The bulb keel is a fin keel with a lead bulb added to the bottom. The bulb has an efficient shape, making it more efficient than just the fin alone.

Wing Keel Like a bulb, a wing keel works by adding more weight and hydrodynamic force to the bottom of the keel. As a result, the wings look like a little airplane mounted on the bottom of a fin keel. 

Swing Keel A swing keel is a fin that pivots up and into the boat, meaning that you can have a very shallow draft when you are docking or anchoring but also a very deep draft when you are sailing in open waters. This heavy keel requires a powerful and complicated electric or hydraulic-electric system. 

Lifting Keel A lifting keel is similar to a swing keel, only the keel lifts up into the hull vertically. 

Bilge Keels A bilge keel boat has two fin keels mounted at 45-degree angles below the hull. The advantage is that the boat can “dry out.” This makes them very popular in harbors around England, where the massive tidal range means that the harbor is only mud for half the day. 

Centerboard Centerboards look like swing keels, but the “keel” part is just a board. It isn’t weighted with lead or iron, so it doesn’t change the ballast of the boat any. They are often found on smaller sailboats like sailing dinghies, but there are also large cruising boats that have full keels or long-fin keels with centerboards, too. 

Daggerboard A daggerboard is like a centerboard, only it doesn’t swing. Instead, it goes straight up and down like a dagger into its sheath. They’re not only common on very small sailing dinghies but also large cruising catamarans.

Canting Keel Canting keels are some of the latest technology items in racing, so they aren’t found on cruising boats yet. They move from side to side, allowing the crew to precisely control the forces made by the keel.

Types of Rudders – What Steers a Sailboat

As with keels, you’ll see various types of rudders on sailboats. The rudder is one of the most critical parts of a sailboat’s equipment, so the differences in rudders are mostly about how protected it is from damage.

Rudder The rudder is the thing that steers the sailboat. It’s mounted on the back of the boat, sometimes looking a bit like a second keel. When the operator turns the steering wheel or tiller, it moves the rudder one way or the other. That, in turn, turns the yacht’s bow left or right. 

Transom-Hung Rudder The most basic type of rudder is hung on the transom. It’s usually controlled with a tiller instead of a wheel. You can see a transom-hung rudder above the water.

Keel-Mounted Rudder On a full keel boat, the rudder will be mounted on the back edge of the keel. This protects it completely from damage since anything the boat might hit will hit the keel first. 

Skeg-Mounted Rudder The rudder might be mounted to a skeg if a boat has a fin keel. A skeg is a small fixed surface that holds the rudder and supports it. In the case of a full skeg, it also protects the rudder as a full keel would.

Spade Rudder Spade rudders have no skeg, so the entire underwater surface moves when you turn the wheel. Most modern yachts have spade rudders because they are incredibly effective. They are easily damaged, however, which is why some offshore sailors still prefer skeg-hung rudders.

Bottom of Sail Boat – Running Gear

Running gear is the generic name given to all equipment under the boat that connects to the engine and moves the boat under power. It consists of the propeller, prop shaft, and supports. 

Propeller Also called the prop or screw, the prop is what converts the engine power into thrust. The water flow over its blades creates a pushing force that moves the boat. Since the sailboat doesn’t use the propeller when it is sailing, sailboats often have folding or feathering props that stop moving.

Prop Shaft The metal shaft that connects the engine to the propeller is called the prop shaft. 

Cutlass Bearing Where the prop shaft exits the hull, a rubber cutlass bearing keeps it centered and rotating freely. 

Saildrive A saildrive is a common arrangement on modern sailboats that uses a vertical drive leg with the propeller. The saildrive installs on the back of the engine and includes the transmission. It’s like the lower unit of an outboard motor, but you cannot raise it out of the water. 

Up Top – Types of Sailboat Designs

Aft Cockpit The “classic” design of the modern sailboat, if there is such a thing, is called the aft cockpit. This layout has the cockpit in the rear-most section of the hull, behind the cabin.

Center Cockpit The center cockpit sailboat has the cockpit closer to the mast. That leaves a lot of space in the rear of the hull for a huge stateroom. This design means that the cockpit will be closer to the boat’s center, making handling easier. But it is also higher, making more windage and motion at sea. 

Pilot House A pilot house sailboat has a second helm inside a protected area. These are popular in colder climates, where the pilot house provides a warm place to steer the boat from. The rear cockpit is usually smaller than a typical aft cockpit, but it’s still where the sail handling occurs. A pilot house has a raised level, so the salon typically surrounds the interior helm to utilize that space and visibility when not underway.

Deck Salon Like a pilot house, a deck salon has big windows and better visibility than a typical sailboat cabin. But it lacks a true interior helm. Many, however, have nav stations with forward visibility and autopilot controls, making it a comfortable place to sit and keep watch during a passage. 

Flush Deck Most sailboats have a raised coach roof where the interior cabin is. But some designers make their decks flush with the sides of the boat, making a wide open deck that is easy to move around on. 

On Deck Sailboat Components – Sailboat Front

The deck of a sailboat is all about safety at sea. Most modern cruising boats are rigged such that there are few things you might need to go “out on deck” or “go forward” for. Instead, these things are rigged back to the cockpit, so you can stay safe and dry while doing your thing.

Since the wet pitching deck of a sailboat at sea is tricky, many of the things you’ll find there are safety-related.

Handholds Places to grab should be located all over the boat, so there’s never a risk of not having something to hold onto to stabilize yourself.

Lifelines Lifelines run the perimeter of the boat and provide a last-ditch safety device. You can grab them, and they should be high enough that they’ll keep you from going overboard. 

Stantions The stands that lifelines attach to.

Bow Pulpit The solid rail around the front of the boat provides a safe handhold and a starting point for the lifelines.

Stern Pushpit The same, but on the stern of the boat.

Bulwarks The raised edges of the deck on the sides so that you can’t slip overboard on accident.

No-Skid Decks In areas where people will be walking, the deck is treated with a special product to make the deck “no-skid.” That way, it isn’t slippery, even when wet.

Harness Sailing harnesses are designed to clip onto the boat and keep a sailor onboard even if the boat takes a huge wave or the sailor slips. The harness is the staple of offshore safety. 

Jack Lines Jack lines are temporary lines secured on the deck where sailors can attach their harnesses. 

Safety Rails Many boats also have extra rails and handholds located in spots where sailors might work on deck, like around the base of the mast.

At the bow of the sailboat, you’ll find her ground tackle.

Bowsprit The bowsprit is the spar that extends from the deck forward of the bow. They’re used on sailboats to gain more sail area since getting the sail farther forward means you can fit a bigger sail. Some have just a spar, while others have a bow platform that is part of the deck.

Ground Tackle  The generic word for the anchor, chain, and all the equipment needed to use it.

Anchor The anchor is “the hook” that digs into the seabed and keeps the boat in the same place. Anchors are safety devices since they allow you to stop in shallow water. But they also provide access to areas with no marinas since you can anchor offshore and go in on your dinghy. 

Windlass A winch that pulls up the anchor and chain. They can be manual, with a handle, or electric, with a button.

Anchor Rode The generic name for the anchor line. It can be a chain or rope.

Snubber A short length of rope that attaches to the chain to secure it to the boat. 

Cleat A horn-shaped piece of deck hardware used to secure a line or rope. 

Dorade A large vent opening on the deck of a boat which is designed to let air in but not water.

Hatch Hatches are upward-facing windows that you can open to increase ventilation in the cabin.

Locker A generic term for a cabinet or compartment on a boat. 

Going Aloft – Basic Boat Parts of a Sailing Rig

The rig of a boat is the mast and all of its associated parts. If you’re wondering about the many different kinds of rigs that are out there, check out our rundown on sailing terms . There you’ll find definitions for boats with just one mast or multiple masts, like sloop rig and what a boat with two sails in front might be called. It’s a cutter, if you’re wondering.

Spar A generic name for a mast, boom, or any other long pole used to hold a sail. It can be wood or metal or vertical or horizontal. 

Mast A vertical spar upon which a sail is hoisted.

Boom A horizontal pole that holds a sail and gives it shape. 

Standing Rigging The wires or rope that holds the mast upright. 

Stay Standing rigging that goes fore to aft. The head stay runs from the masthead to the bow, and the backstay runs from the masthead to the stern.

Shroud Standing rigging that goes to the sides of the boat. From the masthead to each side runs a cap shroud. Some masts also have intermediate and lower shrouds.

Running Rigging All lines that are used for sail handling are called running rigging. 

Halyard A halyard hoists a sail to the top. Each halyard is named for the sail it hoists, i.e., main halyard, jib halyard, spinnaker halyard.

Sheet The sheet controls the sail. If you ease the sheet, the sail is loosened. If you winch the sheet in, it is tightened. Like all running rigging, each sheet is named for the sail it controls, i.e., main sheet, jib sheet, etc.

Traveler If a sail has a boom, the traveler can be used to adjust it from side to side. The sheet is attached to the traveler. Most main sail travelers are located near or in the cockpit.

Gooseneck Fitting The articulating attachment that holds a boom on a mast.

Topping Lift A line that holds the rear end of a boom up. It runs from the masthead to the boom. 

Vang A control line pulls the boom down and puts pressure on the sail to keep it flatter. Large boats may have hydraulic or solid vangs.

Blocks The rest of the world would call this a pulley, but sailors call it a block.

Fairleads Deck organizers that keep the lines tidy and running in the direction they should go on deck.

Furler Wraps the sail around the stay so that it doesn’t not have to be raised and lowered each time. Instead, you pull on the sheet and the sail unrolls or “unfurls.”

On Deck – Back of Sailboat

On most boats, the cockpit is located at the back. 

Cockpit The main operations center and party central on a sailboat. This is where the skipper sits at the helm, and the linesmen control the sheets.

Coaming The cockpit is protected from waves and splashes by the coaming, the tall walls that enclose it. It also makes the cockpit safe since you are unlikely to get swept overboard from here.

Lazarette The main storage locker in the cockpit.

Helm The station where the skipper steers the boat from. 

Tiller If a boat doesn’t have a wheel, it will have a tiller. A tiller is just a handle connected to the rudder, and the skipper pushes or pulls it to steer. Even if a boat has a wheel, it probably has an emergency tiller in case the steering system breaks.

Winch Winches provide a mechanical advantage to make it easier to haul in lines. In the cockpit, all the sheets have winches.

Rope Clutch A clutch locks a rope in place so it can be taken off a winch, even when loaded.

Jammer A jammer does the same as a clutch, but it’s a simpler device found on smaller boats.

Weathervane Steering A weathervane is used to steer the boat like an autopilot but uses wind direction and mechanical linkages. As a result, they use no power and never complain about their workload. They mount on the stern of the boat and are controlled by simple lines to the cockpit. Windvanes are often referred to by their brand name, i.e., Monitor or Hydrovane

Davits Arms on the back of the boat that lift the dinghy or tender. 

Swim Platform A flat area on the transom that allows you easy access in and out of the water. A standard feature on newer boats but not on older ones that just had long swim ladders.

Catamaran Sailboat Parts Explained

For the most part, the components of a catamaran share the same terms and labels that they would on a monohull. Cats often have a few extra features with other names, however.

Hulls A catamaran is made with two hulls connected together. Each hull has an interior, just like a monohull sailboat does. The cabins and heads are usually located in the hulls, and sometimes the galley is also down below.

Owner’s Version A catamaran layout that is made for private owners. Usually, one hull will be dedicated to the owner’s stateroom with a private door, a huge head with a walk-in shower, and a large berth.

Charter Version It has more staterooms and heads than an owner’s version does. Usually, a charter cat has at least two staterooms and heads in each hull.

Bridge Deck The deck connects the two hulls, which usually has the salon and cockpit. If the design is “galley up,” the galley will be on the bridgedeck with the salon.

Cockpit Just like on a monohull, the cockpit is the operations center. But catamarans have huge cockpits, and there is usually a large outdoor dining table and entertainment area as well.

Forward Cockpit Some designs have lounge seating forward of the salon on the bridgedeck.

Flybridge Some designs have the main helm mounted on top of the salon on an upper level. It’s almost the catamaran equivalent of a center cockpit.

Trampolines Forward of the salon, the bridge deck stops, and a trampoline connects the hulls over the water. This is a great place to hang out, but it’s an integral safety feature for a catamaran. The trampolines allow any water to immediately drain away, not weighing the boat down on the bow. This prevents a pitchpole when a boat capsizes by tipping forward into the water.

Cross Beam and Dolphin Striker Since there is no center bow to mount the head stay and foresail, catamarans use a cross beam that connects the hull. A piece of rigging keeps this in place, and it’s called the dolphin striker. No dolphins were hurt in the rigging of these boats, however.

Anchor Bridle Instead of a single snubber line on the anchor, catamarans use a wide bridle that connects each hull bow to the anchor line.

Parts of a Sail Boat FAQs

What are parts of a sailboat called.

Sailing is a challenging hobby, and one reason it’s so difficult for beginners is because every part of a sailboat has its own name. From each wire and rope to every piece of deck hardware, a beginner must learn the basics before they can even start.

What is the front part of a sailboat called?

The front part of a sailboat is called the bow. Many boats also have a spar extending forward of the hull, called the bowsprit.

What are the 5 basic parts of every sailboat?

Every sailboat has at least these five parts, but most boats have many more.  Hull Keel Rudder Rigging Sails
