I can't find anything about it but the concept drawings.

I haven't heard a word but it looks nice.

Cool! I wonder when JC will be bringing one in?


I'm boatless.

Is it me or are the new F16's (Nacra, now this) getting flatter across the bottom? I guess if you can get it up on a full hull plane going downwind, it would be faster, but what about the trade off, going upwind?

When a boat heels a flat bottomed hard chined shape becomes a vee. Said shape should go to weather better...I think...maybe..

Well, why no chines on anything else then? I think the roundness is to reduce overall wetted surface, upwind and down, but it's a compromise, as is the flat bottom.

Prolly a little bit of fashion consciousness and I think it would be hard to get out of the mold. Having a hull "locked" in the mold is not good.

I'm reminded of a youtube video I saw once but now cannot find, of a catamaran that was basically two surfboards for hulls. The designer claimed that it was much faster than the wave piercing designs that are currently in vogue.

It was impressive but they needed...a Spinnaker!

I'm still waiting for someone to join two foiling Moths toghether and have a poor man's foiling cat!

That's been done too. I saw a video (again, I can't find it now) of an A-Cat that had foils on the daggerboards and a foil on a single rudder in the back. The thing didn't heal at all because of the forward foils (or maybe because the wind was light?)

Dave Carlson made up a Cheetalope A cat with an in verted A type foil I believe.

Check this out: http://www.fastsail.com/catcobbler/ and http://www.fastsail.com/catcobbler/afoil4.html

I would think it would not be too hard for one of the more creative A cat builders to put in some sort of angled dagger board slots, front and rear, where you could slide in 4 regular dagger boards, one at each corner, at say a 45 degree angle, which at speed would lift both hulls up evenly, by the four corners (where the daggers would be, or around the beam mount areas), and use standard rudders (although deeper) to steer it.


The biggest problem I see is trying to use T foils, where it's a pain in the butt to put them in/take them out, when trying to launch the boat, like the old Hobie Tri Foilers, not to mention the 'weed catching' ability of a T foil.

That's a cool boat, but in the second video, you see how many guys it takes to launch it, and at about 4:35 into the video, you see what happens when it encounters weeds!

So how about just going for a bike ride around the lake, when there's no wind?
