Heres a new rendering of my new favourite bi-foiler the KissKut.

Here are the numbers:

LOA 4.5 m=14.7'
Beam 4.5m=14.7'
SA=9sq.m=97 sq.ft
weight est.=40kg=88lb.
Price-an amazing(!) $42,000US no peoples foiler if this price is accurate.

I see some problems with veel heel-if anybody else does and can articulate it I'd sure like to know. Appears I have the wing angle slightly too low-that means max veel heel would be greater than this while maintaining the same clearance between buoyancy pod and water as between hull and water. I still don't like the twin vertical struts or the 7'(est) long main foil. A couple of things are immediately obvious: there is too much mainfoil area* and along with the twin struts that results in a drastic increase in wetted surface with veal heel when keeping the leeward tip the proper distance below the surface.

* estimated 3.5 sq. ft.; foil loading with 320lb crew=93lb/sq.ft. Moth foil loading=160lb.per sq.ft. approx. This foil could be shortened to approx. 4' with a 6" chord. and ha
ve the same foil loading as a Moth and that is with TWO people on board KissKut. That would help everything... but it would be even better when jumped with manual control and dual midship wands.

Some mothies think it won't work. To that I say horsepetunias
