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.

| B L / L | In this example L = 11.0 and beam waterline B will be: |
| Figure 2 | |
| B = 1.09 | A narrow beam, of under 1 meter, will be impractical in designing accommodations in a hull. |
| B = B / T | A value near 2 minimizes friction resistance and slightly lower values minimize wave making. Reasonable values are from 1.5 to 2.8. Higher values increase load capacity. The deep-V bottomed boats have typically B between 1.1 and 1.4. B has also effect on boat displacement estimation. |
| T = B / B T = 0.57 | Here we put B = 1.9 to minimize boat resistance (for her size) and get the draft calculation for a canoe body T (Figure 1). |
| Midship coefficient – C | |
| C = A / T (x) B | We need to estimate a few coefficients of the canoe body. where A is the maximum cross section area of the hull (Figure 3). C depends on the shape of the midship section: a deep-V-section has C = 0.5 while an ellipse section has C = 0.785. Midship coefficient has a linear relation to displacement. In this example we use ellipse hull shape to minimize wetted surface, so C = 0.785 |
| Figure 3 |
| C =D / A × L | where D is the displacement volume (m ) of the boat. Prismatic coefficient has an influence on boat resistance. C is typically between 0.55 and 0.64. Lower values (< 0.57) are optimized to displacement speeds, and higher values (>0.60) to speeds over the hull speed (hull speed ). In this example we are seeking for an all round performance cat and set C := 0.59 |
| C = A / B × L | where A is water plane (horizontal) area. Typical value for water plane coefficient is C = 0.69 – 0.72. In our example C = 0.71 |
| m = 2 × B x L × T × C × C × 1025 m = 7136 | At last we can do our displacement estimation. In the next formula, 2 is for two hulls and 1025 is the density of sea water (kg/m3). Loaded displacement mass in kg’s |
| L = 6.3 | L near five, the catamaran is a heavy one and made from solid laminate. Near six, the catamaran has a modern sandwich construction. In a performance cruiser L is usually between 6.0 and 7.0. Higher values than seven are reserved for big racers and super high tech beasts. Use 6.0 to 6.5 as a target for L in a glass-sandwich built cruising catamaran. To adjust L and fully loaded displacement m , change the length/beam ratio of hull, L . |
| m = 0.7 × m m = 4995 | We can now estimate our empty boat displacement (kg): This value must be checked after weight calculation or prototype building of the boat. |
| m = 0.8 × m m = 5709 | The light loaded displacement mass (kg); this is the mass we will use in stability and performance prediction: |
| The beam of a sailing catamaran is a fundamental thing. Make it too narrow, and she can’t carry sails enough to be a decent sailboat. Make it too wide and you end up pitch-poling with too much sails on. The commonly accepted way is to design longitudinal and transversal metacenter heights equal. Here we use the height from buoyancy to metacenter (commonly named B ). The beam between hull centers is named B (Figure 4) and remember that the overall length of the hull is L . | |
| Figure 4 |
| Length/beam ratio of the catamaran – L | |
| L = L / B | If we set L = 2.2 , the longitudinal and transversal stability will come very near to the same value. You can design a sailing catamaran wider or narrower, if you like. Wider construction makes her heavier, narrower means that she carries less sail. |
| B = L / L B = 5.55 | Beam between hull centers (m) – B |
| BM = 2[(B × L x C / 12) +( L × B × C x (0.5B ) )] × (1025 / m ) BM = 20.7 | Transversal height from the center of buoyancy to metacenter, BM can be estimated |
BM = (2 × 0.92 x L × B x C ) / 12 x (1025 / m ) BM = 20.9 | Longitudinal height from the center of buoyancy to metacenter, BM can be estimated. Too low value of BM (well under 10) will make her sensitive to hobby-horsing |
| B = 1.4 × B | We still need to determine the beam of one hull B (Figure 4). If the hulls are asymmetric above waterline this is a sum of outer hull halves. B must be bigger than B of the hull. We’ll put here in our example: |
| B = B B B = 7.07 | Now we can calculate the beam of our catamaran B (Figure 4): |
| Z = 0.06 × L Z = 0.72 | Minimum wet deck clearance at fully loaded condition is defined here to be 6 % of L : |
| EU Size factor | |
| SF=1.75 x m SF = 82 x 10 | While the length/beam ratio of catamaran, L is between 2.2 and 3.2, a catamaran can be certified to A category if SF > 40 000 and to B category if SF > 15 000. |
| Engine Power Requirements | |
| P = 4 x (m /1025)P = 28 | The engine power needed for the catamaran is typically 4 kW/tonne and the motoring speed is near the hull speed. Installed power total in Kw |
| V = 2.44 V = 8.5 | Motoring speed (knots) |
| Vol = 1.2(R / V )(con x P ) Vol = 356 | motoring range in nautical miles R = 600, A diesel engine consume on half throttle approximately: con := 0.15 kg/kWh. The fuel tank of diesel with 20% of reserve is then |

Im working though these formuals to help in the conversion of a cat from diesel to electric. Range, Speed, effect of extra weight on the boat….. Im having a bit of trouble with the B_TR. First off what is it? You don’t call it out as to what it is anywhere that i could find. Second its listed as B TR = B WL / T c but then directly after that you have T c = B WL / B TR. these two equasion are circular….
Yes, I noted the same thing. I guess that TR means resistance.
I am new here and very intetested to continue the discussion! I believe that TR had to be looked at as in Btr (small letter = underscore). B = beam, t= draft and r (I believe) = ratio! As in Lbr, here it is Btr = Beam to draft ratio! This goes along with the further elaboration on the subject! Let me know if I am wrong! Regards PETER
I posted the author’s contact info. You have to contact him as he’s not going to answer here. – Rick
Thank you these formulas as I am planning a catamaran hull/ house boat. The planned length will be about thirty six ft. In length. This will help me in this new venture.
You have to ask the author. His link was above. https://www.facebook.com/terho.halme
I understood everything, accept nothing makes sense from Cm=Am/Tc*Bwl. Almost all equations from here on after is basically the answer to the dividend being divided into itself, which gives a constant answer of “1”. What am I missing? I contacted the original author on Facebook, but due to Facebook regulations, he’s bound never to receive it.
Hi Brian, B WL is the maximum hull breadth at the waterline and Tc is the maximum draft.
The equation B TW = B WL/Tc can be rearranged by multiplying both sides of the equation by Tc:
B TW * Tc = Tc * B WL / Tc
On the right hand side the Tc on the top is divided by the Tc on the bottom so the equal 1 and can both be crossed out.
Then divide both sides by B TW:
Cross out that B TW when it is on the top and the bottom and you get the new equation:
Tc = B WL/ B TW
Thank you all for this very useful article

Formula 16 Catamaran Class Rules
Formula16 Rules V3 2016
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. INDEX

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.

Latest Aussie Blade hits the water.

Lick the knife.
have attached a photo of Marcus sailing the first "Formula Catamarans Australia" Blade F16 to hit the water. The second boat which he will be sailing at the Global Challenge is already in the Netherlands.
I went over to Adelaide on the weekend and sailed this latest version of the Blade F16, I brought it home with me. Before you ask, this boat is fitted with all the standard gear as supplied by FCA, alloy wing mast etc., before I say any more I would like to make the following announcement.
"I will be acting as an agent for FCA, so the Blade will be available for Demos etc. I intend to participate in as many regattas as I can on the East Coast of OZ. I will be able to answer most queries regarding equipment, prices etc. soon. So look forward to answering any queries and having the boat available for Demos from the start of Sept. If you have a regatta on and want to see the Blade, just let me know when and where and I will see what I can do."
WOW! the FCA Blade is amazing in every way . The standard of finish and workmanship by the hull builder Tony Barrett is amazing, I had the pleasure of seeing a partialy built boat in the factory . I have been involved with many Fibreglass factories since first selling sailboards for Hawke Bros. in 83'and I can say without a doubt the finish and attention to quality internaly is the best I have ever seen . No drops of glue or filler or drips of resin anywhere and the strength of the structure and there is lots of it inside, looks bullet proof.
Then the fit out and assembly by Marcus again WOW! I have been frusrated by how long it has taken Marcus to get the first FCA Blade F16 on the water . But now I can see why, the attention to detail and the number of custom made fittings and simplicity of systems is nothing but professional and of the highest standard, no wonder it has taken time, now I can say it was worth waiting for . Don't get me wrong though, it was a rush at the end and some things still need finishing, but for the first sail on the first boat on the water it is well on the way.
The crews that go to Zandvoort and see the FCA Blade will be impressed I am sure.

we are on the east coast of Australia! when are you going to come along to our regatta's?
http://www.catsailor.org/phpBB2/viewforum.php?f=9
I heard you are coming up to the brass monkey next w/e and also the top gun regatta,
Is this correct.
nswmossie.com 1635
I wont make it to Brass Monkey, just to soon. Will be at Forster and Kurnell Top Gun if all goes to plan.
No plans for doing the big trip across Bass Stait at the moment. My large amounts of travel are because I can drive for no cost. Am afraid shipping to Tas adds cost I can't afford, unless I can make the wagon water tight?

Only took two years, but the rumor is that a blade f16 has landed in Tas. Unfortunately in the opposite end of the state... meh

Hi I am presantly looking at purchasing a new Blade from formula the biggest issue is transport which the person is trying to work out, I live in Townsville and a long way from Adelade, anyway a few questions, it gets very choppy up here how have you found it handles the chop, also how is hull bouncy as I am 90 kg and sailing it one up, If there is anyone out there that has one let me know how it handles, and if I get one and transport is fine I have a friend also looking at getting a F16. I was looking at the viper but heard they make the hulls over seas is this also correct

Vipers Hulls are made in Thailand.This should not sway your thoughts on the VERY well made boat. All AHPC gear is of a very high standard.
Tony Barret has a blade similar weight and he sails one up. He will also be building your Blade if you decide to get a New one.
Give him a call at the Fiberglass Factory
0883260877 I'm sure he will help with any details you need.

Danny - I cant believe you would make a statement like that. Once again you have fired your mouth off without thinking first. Tony manufactures the hulls, not the complete boat.
Not sure if the Razor has hit the water yet. But Russell finally got wet yesterday. I am very happy, only the port forward compartment had very minor water. Nothing broke although I only sailed cat rigged, main only. My out haul popped off the end of the boom, so I decided to head in.
I never felt really fast, but up wind I was comparable to the 5/8's and the Taipan, It pointed really, until the out haul problem.
A promising start.

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.
