Wings are class legal as long as they measure. Build one and see how it goes. As you may be aware some have been built but have yet to show enough all round speed to place highly in a championship event. I suspect a wing would have ended up in the pool at the tiki bar at Islamorada!!!!!

Willy,

I would bet yours is "Wild Turkey" not sure of the spelling, it was probably in the mid 80'

Yup It's Wild Turkey,
A lovely boat.
Built by the Patient Lady Crew, lead by Terry Richards, Skip Banks and Brad Johannson.
She was designed by Brad but had more Patient Lady DNA than he probably would have liked.
His hull form was a bit more NACRA like than the Hubbard/ MacLane shapes.
She was owned for a long time by Craig Richardson in California.
I don't know where she ended up, might still be in a race car box in his driveway.

Nacra did something 18sq ish back in the day. Skip the Nacra 36 bit.

Sighted in the Video: Simon McKeon, ( sailing) Graeme Fraser ( pulling the platform upright) and Lindsey Cunningham ( thinking really hard) .
Wing is practically identical to the Wild Turkey wing.
Pieter Den Hartog was probably the lead builder. He was around the Norwalk shop before leaving for Hawaii.
I still have the mold for his Div II sailboard under the shed.

Steve,

Which D2 sailboard mold? Just curious. I used to love those boards.

Sorry for the hijack but it sounds like I'm being greedy, hanging on to three Div 2s - a mid '80s custom with track and fully retracting CB, early '80s TC Win by Georg Lechner, and the Lechner A390 that took the bronze at the Barcelona Olympics. The design progression is interesting to see. and one of those things that looks obvious after you have seen it!

Cool to hear that Wild Turkey is still OK; I remember the Wooden Boat article on the wing.

sounds like a great amount of fun from the good old days but the original question was what was the outcome of discussions at the A Class A G M where the future of wing sails was on the agenda

Have to make a correction to the Wild Turkey discussion. The boat was owned by Craig Riley. We raced against each other on many occasions and he is still my carbon supplier today.

the Wild Turkey photo was taken at the Monterrey Multihull Classic which was a pretty big race in the mid 80's. He could point like crazy and didn't have much trouble beating the tornados to the weather mark, but he was new to the boat and had not yet learned a fast downwind technique. in those days putting the boards down and flying the hull downwind was a fairly new concept and i don't remember seeing him do that.
the 18 square class had 2 divisions and he was in the light division i believe as were all the Johansen boats. i think windsurfing may have had a hand in the loss of interest in the class. that and the introduction of the spi. to beach cats.

Pieter designed and built his own board, it was very boat like with a bow and elliptical sections throughout.
He built a high temperature mold just before he lefty for lotus land.
So the sky is the limit on technology that could be wasted on this thing.
If anyone wants to do anything with this; his web site is:

John: Right it was Craig Riley. Craig Richardson is someone else I know who is also a very cool guy, but not with the catamaran cred. Do you know if Turkey is still in his possession?

Do I vaguely remember it being for sale in the Multihull Magazine classifieds 5, 6, 7 or so years ago?

just had a wicked idea. I'm building an Oppikat for the grommets, ordered the laser cut bulkheads last week. Would be the bees knees and the talk of the Yacht club bar to stick a wing on it…. Yeah, I know, stupid idea, but so is building an 8' long training catamaran.

well, to my knowledge the German guy never reported back on the performance of his winged A cat, and this thread is all over the map so…a wing on a 9" cat?? i thought about it for the 9"8" that i built, but the reality is that there was already a free windsurf rig to use. once rigged and sailed, the rig's all up light weight and efficiency of the camber inducers kind of makes me think that a wing would not make up for it's weight at such a small scale. please prove me wrong and i'll make one too, but first i'll need to get my foils created and installed to get the boat foiling.
now for my question; Apparently there are trimarans with banana boards and "T" foils that can fully foil. is there any reason why a beach cat wouldn't foil with that set up? maybe with winglets at the end of the daggerboards. if the answer is yes then it could be applied to say an 18 square, an illegal "A", my 9'8"/3m, or any small cat for those that like to tinker.

The discussion was that as we already know wings are class legal as long as they measure. There was no move to change the rules to ban them. It was decided to monitor progress in their development to see if anyone actually got any good results in major championships and then consider if there were any issues which required addressing.
So business as usual in a development class. There are many things tried, some succeed and many fail. But the joy is that we all keep trying.

Not at all hard to do.
Made easier by the fact that the thing is small enough....
Think surfboard and you are half way there.
Hot wire, flotation billet and a bit of glass and
The kids can paddle it around when they aren't sailing.
It might even be cheaper than buying a mast and sail!

I would hand shape or hot wire out the airfoils, and laminate glass skins on them.
Probably two element wing with area split 50-50 between flap and main wing.
So small you don't need anything other than boom height control arm to control camber.
