Stunt 9: Benchmarking Stable Flight

The Stunt 9 by Michele Petrucci has not raced yet and it is not aimed neither to perform in a regatta. 
The goal is to provide rock solid stable flight for recreational & skilled sailors alike.
And that is what the this boats delivers.

But with the decision the US AClass Assoc has taken yesterday on eliminating Rule 8 (See previous post below),  T foils solutions might now have a place in US regattas, although active trimming like wands are definitely not allowed. Thus the chance to develop an Eagle 20HF T Kite foil without any active hardware trim, 

 relying only on design & sailors input.

This is not happening in the video above, the Cat is going like on rails, perfect flight with little or none sailors active trim as we need to exercise in the A-class and even the FP or F20.

Great achievement by Michele, currently on Stunt 9  production series.

A-Class: US Association votes to eliminate Rule 8

A-Class Rule 8:
8. 8.1 No part of each hull or hull appendages below the waterline shall be less than 0.75 meters from the centre line.
8.2 Movable and retractable hull appendages shall be inserted from the top or be capable of being fully retractable into the hull.//

Current A-Class Rules:

Report by Bailey White, US Class President posted at USACA fb page:

"Big day today. We had perfect racing conditions and an excellent class meeting for Canada and USA members. We have voted to suspend rule 8 which limits foiling technologies for our regattas for two years to learn more about foiling.
We have not modified any other rule. This is a change just for our two countries before we make a proposal to the world members.

The A-Class is the fastest growing and possibly largest foiling class of any kind in North America. This has happened in the last year alone and the growth in unprecedented. We have almost 50 foiling boats and have now voted today to allow boats to put foiling boards in from the bottom and eliminate all other restrictions to encourage all members to experience the incredible sensation of flying. Whether you have a new boat or an old boat, you will be able to inexpensively fly".

If you want to fly, join us!


Just yesterday I was talking with a well known A-Class & Moth sailor on how at this point with a no return to floating mode I had many sailors here thinking twice on joining the As, as they are all waiting on what just happened in the US fleet yesterday.

The spirit is "If you gonna Foil, Foil good" , thus many young talented sailors are looking to go Moth instead of A.
And I think is time to go in that direction, kudos to the US Assoc members on stepping up an acting according their will.

Bailey told me they are having so much fun, that they saw no point on keeping current foil aimed restriction.
This a really good reference for IACA , as the US Class might have the most varied type of A-Cat designs actually racing together, as there are lots of custom built boats and old design now sailing against the latest tech from Europe that arrived to US fleets last within last year.

Of course I don´t know if this will conflict in any manner with IACA, as in Italy they just formed anther Class to go full floating.

In the US Class reign, eliminating this rules means you can put a J board a la FP from the bottom of the hull, and there is no restriction on how far inboard the foil can go.

This will not make a J board A-Cat an instant winner, as the US Class will continue to race in 5knots (I hope) and there the TNZ /FP style Js are quite draggy as seen with the FP in mid to low wind range conditions, issue that can only be fixed with added sail power as reported with the F20FCS.

An if there is something the A-Cat lacks , is raw sail power in the low range. Thus today at least and in my view a TNZ/ J will struggle bad time in 5-6knots. 

Now in the mid range we might see a well refined foil perform. But that is something yet to be seen in a race.

Current DNA, Exploder & Scheurer design foiling packages will keep an edge in the overall as they are doing against the floaters now even in 5-6knot regattas as seen at last French Nats past weeks. Note that 'cassettes' foil cases boats are racing at this North Ams, and also raced at Takapuna. Current leaders at St Andrews Bay Yacht Club are racing Exploder, DNA, Exploder production foil setup.

Additionally we might not need to insert from bottom, just check Arno´s full foiling concept (one under current IACA official rules) published some weeks ago. I will surely go for a solution inserted from the top or a good way to keep foil leveled with bottom for our special coast launching conditions.

This local rule change (I don´t know how IACA can react with US Class)  will not allow active trim a la Stunt 9 , but now for instance you can fit (at US regattas) a Kite refined T foil a la Eagle 20HF (checking you are inside the 2,30 width limit).

Practice Race Images by Walter Cooper / North Americans official web --
Matt Struble leads the 2015 North Americans at Panama City, FL with 3 bullet under his belt. Racing Ben Moon's Ronstan Exploder, Matt has being able (after much work on the boat as I've been told) to grab the pace of a foiling A for the first time. But Matt knows 1 thing or two about racing & technical details, he is 2013 NA Champ sailing with his own built design.

Second place for 2014 North Americans Champ, Bruce Mahoney, with a DNA 2015 latest tech, Bruce scored three seconds behind Matt. Still much to go but Bailey White, Class president & currently in third place (3,3,4)  and also with Exploder told me he was impressed on how Matt adapted to a new boat and foiling mode so fast , he is faster and pointing better foiling downwind than the rest of the fleet.

Honoring Olympic & Multihull Sailor Charles 'Carlito' Favre

Charles Favre sadly passed away last Thursday while sailing an A-Cat. I saw condolences for from several sailors, and realized he was a beloved friend by his peers, and he got plenty, just analyzing the boats he sailed : Olympic 470 & Tornado, X40s, D35s, M2s and A-Class among others.

I didn´t knew him as I know other sailors in Europe, but I do remember him from 2014 Bordeaux A-Class Europeans, Why? Because he was always smiling and was the most cordial sailor to us newbies/rookies of the Arg team.

On some mails I exchanged with people who knew him  I told exactly that to Arno earlier today before getting Kris Jonsson words minutes ago.
Reading how Kris describes his friend Charles, confirms the impression I had from him.

There is a good picture from that event taken by Paula Kopulowicz on Favre getting inside Waterhouse & Landy at the upwind mark at Bordeaux Europeans 2014.
First image left: At helm onboard Tilt M2 by Loris von Siebenthal. 2nd Pic: Sailing A-Class , image by Gianluca Mini.

I received several requests to publish on his passing but I wanted someone who knew him well to write some lines to honor 'Carlito' as he was also known. Sandro Caviezel & Charles Bueche contacted Kris Jonsson.

Charles passed away sailing an A-Cat, and we don´t know the cause yet. But the Multihull and sailing community will remember him on the several projects embarked through his good sailing Life. This is our humble way to honor him.
Sail On Charles.

Below words by his fellow A-Cat sailor & friend Kris Jonsson:   "Charles Favre left us unexpectedly last week on Thursday. Our thoughts are with him and his family. We still can't accept that he is no longer with us here. He was a great sailor and friend who we admired for his passion, kindness and desire to evolve, learn and win. It will take time to digest.

He was out practicing on his new A Class, one of three new boats we recently received. We had spent a good deal of the past week-end together preparing the boats. We were all very excited about the new boats and eager to get on the water. While I had to travel during the week he had already been out on Wednesday trying it out. I got a happy email in the morning from him explaining the previous day of sailing. This was Charles' third A Class having sailed already on two earlier generations.

There were several boats on the water during the afternoon on Thursday but when the others went ashore early evening Charles decided to do one more tack over towards the other side before reaching back to Corsier. I recall many times where one of us would stay out a bit longer to take advantage of the conditions to get another run and then to find our friends back ashore after a good day of sailing. This was not the case Thursday unfortunately.

Charles was found shortly thereafter next to his capsized boat off Corsier Port, on his back unconscious still hooked in to his trapeze, and later passed away.. The exact cause of the accident is not known. The guys did an exemplary job rescuing him by boat, trying to save him followed by transportation in helicopter to the University hospital - but It was too late. Charles left us and his family, far too early.

When I speak to Charles' friends that grew up together there are endless stories about friendship, regattas and championships. I was fortunate enough to get to know him over the past years, first during the D35 series during after sail recaps at Madame L'Huillier's cabin and then later when we started sailing A Class together a few years back.

Many memories stand out, one of my favorites being coming from windy and cold November conditions on the A Class jumping straight in to Schneiter's outside jacuzzi and sharing on the water experiences with jokes and smiles - shared passion. He was such an enthusiastic and positive person, fun to be around, and as we know he could also be quite serious on the water at times with a certain temperament!

He had a long career in sailing including the 84' Olympics in Los Angeles in 470 and then the 92' Olympics in Barcelona on Tornado and many victories on the lake and abroad. He raced with numerous teams and boats on the lake through the years. He was tactician on the yellow Alinghi when it all started, he was with Cardis' D35 team and with team TILT on various boats. Highly appreciated he was regularly invited back by the teams he had sailed with for the occasional regatta.

The father of three children and the father figure to another three, our thoughts go to his family - he will be immensely missed by us. We will remember him and keep being inspired by him. "

Funeral was done on Wednesday 20 and it was very emotional.-

F18 Worlds 2015 @Kiel: Record Entries confirmed

Image Jasper van Staveren -  Kiel registered entries confirms beyond final nrs that is going to be one of the major F18 Worlds ever.
For  2016 Worlds the local Class & the organizing Club, Yacht Club Argentino, are already working locally and with the IF18CA to start promoting the event. Club official 2016 FB page at
On Kiel, German Class Chair Jens Uwe Tonne comments on the success of the 2015 Worlds:
Press Release IF18CA. Full report at " Kieler Yacht-Club is heading for a new World Record. The Formula 18 World Championship (11-18 July 2015) has already registered 194 entries from 24 countries at the end of April. 

The maximum available slots of 200 catamarans is close from being reached. This has already exceeded the previous record of 185 crews that participated at a previous World Cup in Kiel-Schilksee. The Formula 18 catamaran class is more active than ever for this edition of the F18 Worlds and will give an even bigger push for the future.

“We would be very delighted if there are really going to be 200 teams at our Worlds. But it’s already clear that this will be a great event”, says the German chairman Jens Uwe Tonne. The cause of this strong growth can easily being explained from his point of view. “Germany itself has a large and active fleet with over 55 boats. But it’s also the ‘Call for Kiel’. The famous Kieler Woche is favorite among sailors worldwide and easily to reach by a big fleet of Scandinavian crews.”...

Artemis AC45 'T' @Bermuda

All Images Artemis Racing. Pics For those design fanatics who follow the web. A nice view of Artemis 'Turbo' mods, Click images for HQ. BAR calls theirs just 'F'.  
What a beauty this new AC45 is, getting close to perfection. All functional modifications that brings great refined looks also.
We pointed out them already, but here you can see them better, like beam/case more forward, aero mods, cockpit flare , wheel, grinders etc, and the bowsprit cut like new AC48 Rules. Compare with BAR & Groupama on previous posts.

The question now is are we going to see new foils a la 'Kite' , like the Eagle 20HF?

When Oracle AC72 was launched I referred at it as "Alienware", and beyond the cliche comparison to Starwars,  take a look at Nathan's helmet,..  (I cant believe how good production Designers of that saga were, as their creations still look updated & modern aftet 30 yrs?)

Hey  Remi, you need to launch a new model asap!

BAR Launchs their AC45 'F'

Image BAR - This shot is revealing on the height the AC boys are flying. If the Nacra F20 felt too high imagine a ride not on the AC45 but the AC72? The platforms are bigger & different, thus the feeling might not be the same, still flight 'altitude' is one to respect.

While Oracle / Artemis are on the Turbo versions , BAR & Groupama are in the 'pre historic age' first 45 foiling steps. Nevertheless it might interesting to know  how the new Aero and  beam/case placement mods affects final performance on a matchup between OR/AR AC45 'Turbo'  vs the spartan BAR/Groupama version.

AC45 & A-Class Training @Bermuda

Nice shot from Bermuda byOracle Team USA. I think that is Nathan Outterdige on a DNA. The A was the missing 'link' in previous Bermuda Oracle toys image.
At current state of development I need to repeat that the As are most indicated flying toys to develop an scaled solution.

With all the resources available, we might expect a quantum leap as the one seen at Takapuna Worlds with New Zealand squad foiling DNA R&D.

But remember Jakub Kopylowicz from Exploder delivered a weapon the low & midrange for Nathan on his own development. So having  unlimited resources is not always the ultimate source of innovations, but it surely helps!  Just ask Oracle at AC34..

Foiling Beachcats on the Run: Eagle 20HF reaches 36.8knots

Image: Michael Ehlers  from past weeks sessionS --. 
When I told you a new Formula Foiling Class was coming it was no joke or wishful thinking. 
Although getting airborne and even final speed does not grant you the meanings to win Course of Long Distance races (Hydroptere, White Dragons, Stunt9  etc) as we've been preaching for long time with the new era of beachcat foilers , this is really an impressive nr from the new Eagle 20HF

Above T wing setup being used at the speed session.
The Flying Phantom was the first efficient foiling racing beachcat then followed by the Nacra F20.

Now If this Eagle HF20 system a la Kite/Windsurf foiling kit can be refined to match FP/ Nacra F20 pointing abilities we will see a new paradigm in foil design.
At least it has demonstrated,  based on reports, that without a complicated Hydroptere foiling kit it has achieved maybe a speed record for small cats.

What was again the speed achieved by the Moth some time ago?? And this is quite near the GC32s one too.

The Eagle 20HF has reached 36.8knots as reported by the yard through Michael Ehlers.
"Hi Martin
In Germany finally the sailing season started and the conditions improved.
Here an update regarding the 20 HF:
"36.8 knots / 68.15 km/h!..... "Is this a new record for 18-20foot double trapeze multihulls?"

Nacra F20 Power in the Low & Midrange: Matchup vs FP II, 8-12knots.

Image from Feb in BA, Cruz & Mariano foiling in 5-6knots. Update: Pete Melvin's coments on the F20 light weather performance at the end of the post.
Summer long gone here in BA, but we are lucky on being able to sail the whole year,  also climate has been really good last months,  till past 2  weeks when we 'suffered' a 'cold' front ,  of course nothing like Northen Europe Cold..

On Sunday we had light winds with only some F18 training, on Sat we went out will all the toys: 2 Nacra F20s, the FP & 4 As & an F18.
I was on the A training so I watched the informal match ups from time to time, but far away to report  first hand. It was 12kntos decreasing to a light 9-8knots when we all came back.

Once in land again, I talked with crews.
The Nacra F20 confirmed what we've saying for a while on size/power logic,  in the low range is all for the F20 upwind & downwind.
12knots  good foiling conditions the Nacra boys reported a total massacre and the FP guys confirmed than in 8-9knots there is nothing to do, but maintained they were doing par or better on 12knots...

As you can see.... there are always different opinions on the same situation. As when I published the first informal test video (discussions were on my pointst of view on the whole day, video simple shows facts)
In fact those sessions accelerated the new Spi design for the F20, Which was been used yesterday,  and the crews report a much better downwind foiling ride. 

Before the first test, the F20 here didn´t even used spi.
Although Fer van West was fully focused on foiling with spi when he came here for the Clinics

On yesterday's informals tests reality marks that the F20 has a real noticeable edge in lower

Nacra 15 is selected as Youth ISAF Multihull

Nacra 15 has been selected by SAF as new ISAF Youth Multihull as just being informed by Nacra in their FB page. --  I didn´t supported Nacra this time around as with the 17 but you need to recognize their work, in fact they are the only ones pushing forward for all range of Classes: From Youths now with the 15, to the F18 and F20 foilers and was pushing for the F16, not anymore of course.
