Sailboat-Data

With the same philosophy than Formula 18 rules, the Formula 16 (F16) rules can be listed as a "box rule" setting limits to the main dimensions of the catamaran. It allows racing single handed (1-up) or double handed (2-up), then the boat is equipped with a jib. F16 Catamarans are designed for light crews (120-140 kg) making them particularly suited to youngs.

• Maximum length 5.00 m
• Maximum beam 2.50 m
• Minimum weight of platform 104 kg 1up and 107 kg 2-up
• Maximum mast height of 8.50 m
• Maximum mainsail area (including mast) 15 sqm
• Maximum jib area 3.7 sqm
• Maximum spinnaker area 17.5 sqm
• Boat must be rightable by crew without external assistance

Created in 2001, this series is recognized by ISAF since 2010.

The Formula 16 (F16) sport catamaran is an ISAF recognised 5 m long beach catamaran with an asymmetric spinnaker setup.

It is actively sailed in two modes: doublehanded with a jib ( 2-up ), and singlehanded without a jib ( 1-up ).

Its class rules setup is very similar to those of the Formula 18 class of beach catamarans.

In effect any boat that adheres to a certain limited set of general design specifications may participate in all the official class races. The two classes, F18 and F16, govern the racing of their own class compliant boats.

The F16 class was founded in the spring of 2001, after it had become clear by the overwhelming success of the F18 class that formula classes would be the future in sport/beach catamarans and that a more versatile formula class was desired.

In handicap racing, the F16 uses a D-PN of 63.0 [1]

In the beginning the F18 class rules functioned as a template for the F16 class rules, but not much later the two rule sets started to diverge. The F16 class focused more and more on a truly lightweight design with a reduced rule set. The latter meaning that all rules governing a particular minor detail in the boat design, like the minimum weight of a rudder board, were dropped. The F16 rules control what is known as a 'boxrule'. Eventually a reduced number of major limits was finalized:

• Maximum overall length is 5 m.
• Maximum overall width 2.5 m.
• Minimum overall weight 104 kg 1up and 107 kg 2-up .
• Maximum mast height 8.5 m.
• Maximum mainsail area (including mast) 15 m².
• Maximum jib area 3.7 m².
• Maximum spinnaker area 17.5 m².

The other main rules are:

• Mid height width of spinnaker is at minimum 75% of length foot.
• Boat must be rightable by crew either solo or doublehanded without external assistance
• The rig may not be trimmed between start and finish by means other than sheet, downhaul, outhaul, traveller, mast rotation and halyards systems.
• Only "soft" sails are allowed.
• No ballast other than corrector weights up to 7.5 kg are allowed

Design goals

The F16 class was from its inception engineered towards a dual-role sports catamaran with certain remarkable qualities. A careful balancing act between the major components of the F16 boats allows this result.

The result being that the same craft is used for both doublehanded sailing/racing as singlehanded sailing/racing; the craft has a very similar performance in both modes (doublehanded and singlehanded); and the F16 boats share as good as identical performance with their intellectual parent, the Formula 18 class.

Several modifications were made to the early F16 class rules to achieve this result. The founders believed this result to be important to the growth and success of the F16 class. Additionally, both the doublehanded and singlehanded F16s race each other for being first across the line as well. They are simply that close in overall performance around the race course.

The other goal that the F16 class was engineered towards was the ease of handling the boat by any singlehanded or doublehanded crew. By far most sport catamarans are designed for use in only one mode, either as doublehanders or as singlehanders, which makes flexible use of these boats cumbersome and in some cases even risky, as quite a few boats require the combined effort of two crew to right it after a capsize. This design goal forced the F16 setup towards a generally smaller and lighter setup so that an average-sized solo sailor can both handle the boat well while sailing and when taking it out of the water and onto a trailer. By increasing further the lightweight character of the design and incorporating several technological advances, the boat could again be made to perform well when sailed by two average-sized adults. In this respect the F16 class had found its own unique character and has set itself apart from its mentor the F18 class.

Class development

The F16 class has a modest following in the USA, Europe, Asia and Australia and class associations have been formed there. The key areas within these regions are Florida/Maryland/California, UK/Netherlands/Belgium/Germany, Singapore/Thailand, New South Wales and Victoria. But during the years 2005 and 2006 the class grew in unlikely places like Shanghai (China), Finland, Arab Emirates and places in the USA like Arizona and New Mexico. The class grows as much in areas new to beach cat sailing as well growing in volume in the traditional beach cat regions. The F16 class is therefore trail blazing a path for a large beach catamaran scene in these places. This is to a large extent due to low-cost home-buildable plans being available next to commercially sold ready-to-sail boats. A good number of these homebuilt wood/epoxy boats race and are very competitive with the glass/vinylester production boats.

The most notable event for F16s in their short history was held in April 2007 where the best 20 teams of the various US sport catamaran classes were invited to compete on Blade F16s at the US Multihull Championship for the Hobie Alter Cup. The Hobie Alter Cup is a long-running invitational championship of catamaran champions named after Hobie Alter who made beach catamaran sailing a very popular sport worldwide in the 1970s. The event was generally a five-day, round-robin on manufacturer-supplied boats to ensure the competition was a test of sailing skill and influenced by differences in boats. John Casey and John Williams won the 2007 event. [2]

In October 2009, the F16s were again used for the Hobie Alter Cup event. This time AHPC provided Viper F16s to the organisation for their use. An unprecedented honor for a class that is still as young as the F16 class. Casey and Williams again won the event. [2]

In November 2010 the Formula 16 Class was granted Recognised Status by the International Sailing Federation the world governing body for the sport. The Formula 16 catamaran had effectively completed its journey from a quirky, enthusiast's catamaran to the mainstream of international sailing.

Formula 16 CLASS

Responsible : Aurore Kerr

Formula 16 is a multi-manufacturer class for beach catamarans, designed for the 21st century.

The F16 design is  modern with a minimum weight of 107kg and few restrictions on materials. Then costs are no more than for other race catamarans. The inclusion of an asymmetric spinnaker adds to the excitement. Moreover, by removing the jib, one can sail single handed, which gives even more opportunities of sailing experience.

The F16 design is  fast . A light-weight platform, generous sail areas and an asymmetric spinnaker can mean only one thing: speed. In 2-up mode the F16 races the F18 class on elapsed time.

It is mainly meant for a crew between 110 and 130 kg, looking for a fast catamaran, wanting to do some nice regattas or just have fun on the water.

The development of the Swiss F16 class has just been incredible these past years , with up to 30 members and around 15 boats shared all over Switzerland. The climax was definitely the organization of the European Championship in Morges in 2017 with more than 42 boats present. With a nice atmosphere ashore and on the water, the F16 class is really friendly and accessible to anyone!

RACING CALENDAR

W est r iver s ailing c lub.

The F16 fleet was established at WRSC in 2010. We have a mix of single-handed and double-handed teams that are competitive. We are part of the catamaran group of friendly and helpful sailors at the club. We race in the Tuesday night and Frostbite catamaran series around government marks from April into November, in weekend races around buoys, as well as distance races around the Chesapeake Bay. You also find us sailing around the West River and the Bay just for fun days on the water.

Come join our competitive and fun fleet!

The Formula 16 catamaran is fun, fast and versatile. It is light and can be sailed, righted, beach launched, and retrieved by a single adult. However, it can be also sailed and raced with 2 people on board. Class rules allow a single-handed boat to race under mainsail and spinnaker directly against double- handed boat sailing under mainsail, jib, and spinnaker, with no handicap between them. Raced double-handed, it is ideally suited to light teams, such as parent/child, mixed gender, or youth teams. Everyone can enjoy the day!

FLEET CAPTAIN

Constantine seremetis.

I started sailing as a teenager on a Force 5. A few years later I had a chance to sail on a Hobie 16 beach cat and I was hooked on catamarans! I sailed a Hobie 16 and a Nacra 5.0 for many years before getting my F16 in 2002. I really enjoy its versatility and feel that the West River is a perfect place for this class. We also have a very close and friendly group at WRSC which makes sailing here that much more enjoyable.

Please email me, at [email protected] , if you have any questions about the F16 boats, our fleet, or our club.

FLEET COMMUNICATION

The F16 fleet is a part of the West River Catamaran Google group. It's easy for anybody to join! This is how the fleet captain, the fleet, and others at WRSC communicate specifically to each other! All important fleet specific information is sent through this group. To join, send a blank email to [email protected] for the admin to approve you.

FORMULA 16 CATAMARAN CLASS RULES

The FORMULA 16 CATAMARAN was designed to a box rule in 2002 by a group of catamaran enthusiasts on 3 continents cooperating via the internet. The formula is designed such that it permits sloop rigged or uni-rigged versions of compliant designs to race each other on an equal basis. Sloop rigged boats shall be sailed with two crew making them approximately level in performance with a solo crew uni-rigged boat. The F16 Class became an ISAF recognised class in November 2010.

2 Formula 16 Class Rules 25nov2016 V3.0 INTRODUCTION

This introduction only provides an informal background and the FORMULA 16 CATAMARAN Class Rules proper begin on the next page.

The strict box measurement rule allows manufacturers to develop catamarans that are competitively priced yet allow freedom to builders to develop toward higher levels of performance. Being open to any manufacturer allows many builders and sail makers to compete and so keep costs to a minimum. The Class remains committed to keeping development under control, maintaining a good balance between cost and performance.

F16CA measures or checks hulls, hull appendages, rigs and sails which are required to conform to F16CA standards, such boat parts only being altered to stay in line with current F16CA rules.

Part 1, Section A covers the administration of the F16CA and Section B deals with boat eligibility. Sections C to G deal with racing, and should be read in conjunction with the ISAF Equipment Rules of Sailing and the Racing Rules of Sailing.

Owners and crews should be aware that compliance with rules in Section C is NOT checked as part of the certification process. The Rules regulating the use of equipment during a race are contained in Section C of these class rules, in ERS Part I and in the Racing Rules of Sailing.

PLEASE REMEMBER:

THESE RULES ARE CLOSED CLASS RULES WHEREBY IF IT DOES NOT SPECIFICALLY SAY THAT YOU MAY – THEN YOU SHALL NOT.

COMPONENTS, AND THEIR USE, ARE DEFINED BY THEIR DESCRIPTION.

The Formula 16 (F16) sport catamaran is an ISAF recognised 5 m long beach catamaran with an asymmetric spinnaker setup. It is actively sailed in two modes: doublehanded with a jib (2-up), and singlehanded without a jib (1-up). Its class rules setup is very similar to those of the Formula 18 class of beach catamarans.

THE F16 WAS FOUNDED IN 2001 AND THERE ARE NOW A NUMBER OF FULLY OPTIMISED DESIGNS. LEARN MORE ABOUT THE BOATS. FIND OUT WHAT'S HAPPENING ON THE CALENDAR OR THROUGH YOUR CLASS ASSOCIATION.

Manufacturer:  Falcon Marine LLC

Designed by Phill Brander and Ian Marcovitch, the F16 Blade was developed specifically to fit the F16 rules. The F16 concept was developed to be extremely fast, light weight, gennaker rigged boat that is not only competitive with much larger designs, but fun and easy to sail. The Blade takes this concept a few steps further by utilizing advantages in modern hull shape technology and adapting a few other of the designers’ own innovations to truly optimize a lightweight 5 meter (16′-4″) platform.

Discover the edge of possible

The standard in Formula 16 sailing. Recreational or highly competitive. The carbon stepping stone.

The Nacra F16 Carbon offers everything race teams look for in a mature racing cat and more. It is the preferred choice for lightweight crews of all ages and is suitable for both double-handed and single-handed sailing.

The boat comes in a full Class approved configuration as standard. But you can easily switch to semi-foiling performance. If you wish to take your F16 even further, there are several exciting options available.

Usage Competitive racing Touring Semi-foiling

Crew Configurable

ALWAYS BE ONE STEP AHEAD

The Formula 16 Class used to be an assembly of ‘homemade’ boats, but ever since World Sailing (ISAF back then) recognized the Class as official in 2010, it matured quickly. From the beginning, Nacra Sailing was convinced that Formula 16 sailing will grow and rise to new heights and so we’ve decided to make a dedicated Class boat. Together with the legendary engineers from

Morelli&Melvin we’ve designed a boat that has become the standard for almost every type of sailor – from the recreational solo-sailor to competitive teams searching for the cutting edge. And of course, it fits perfectly into the Olympic pathway: The Nacra F16 Carbon is the perfect steppingstone from youth to full Olympic sailing.

The racer for sailors with attitude. It is perfect for lightweight single or double crews of all ages. Designed to put sailors in control, the Nacra F16 Carbon is loads of fun to sail, both in racing and touring mode. A very rigid platform Although Formula 16 Class regulations do not yet allow Decksweeper sails, Nacra has made them available anyway. And in maybe the biggest upgrade yet, the F16 ‘s sails are now constructed of Endumax®  – one of the strongest and lightest cloth materials to date.

Superstrong lightweight carbon components give the Nacra F16 Carbon its name. With options such as full carbon mast, boom, spinnaker pole and tiller tie bar, your F16 can be as light as you wish it to be.

NEW MATERIAL Stronger than steel, light as a feather.  The all-new sails made by Olympic supplier Performance Sails are now made of Endumax® , a revolutionary aramid film that is incredibly strong and light. In fact, its strength-to-weight ratio is the highest available on the market. Its unique physical and chemical structure give Endumax® incredible performance, a very high resistance against tearing and other damages, and against UV-rays. Your Endumax® sails will take your F16 to the next level, no matter the circumstances.

The strength of Endumax® sails shows when sailing competitively.

Customize away

You can customize your Nacra F16 Carbon with multiple accessories, upgrades and additions to make your catamaran truly yours.

The F16 class fosters a sense of a community among competitive and social racers. The class aims to work closely with the other formula classes to create a great environment for all sailors. It is both an open class (handicap) and a class racer. In addition to competitive sailing, recreational sailing is an important aspect of the class. These three scenes fully complement each other and none impedes the full exploitation of the other. The F16 class looks forward to welcoming new F16 sailors to their community, no matter what type of sailor you are.
