I saw it on the WPNSA slip last weekend and wondered if it was anything to do with you Grumpf.

Still, well done for getting it out there. It was a little bit breezy.

You owe me a 10er.

In case anyone wondered, it sank, at least the forward compartments of the
nose section filled with water while i was trying to get it on the plane in
what was the best part of thirty knots..

I kind of skimped on the kite bladders in the tow forward sections, had sort
of figured they'd be planing out of the water for the most part anyhow..

Whatever, back to the drawing board, just further proof Cat's are useless..

A pair of waterskis held rigidly together is exactly what it is.

Way back, I used to waterski race. At one time from a limited power source,
and we always found that a pair of skis were always faster than one mono,
and the mono always had more drag, widening the footprint spreads the
load I guess. Unforunately at 50 mph+ a pair of skis were uncontrollable in
chop, no-one could stay up on a pair at very high speed, the stance on a
mono is more stable.

So that and the fact cat powerboats were always faster than mono, we all
know cats are faster than mono dinghies and no-ones ever built a fast cat
windsurf board and there you go..

GRF - what's the thinking behind why it should be quicker than a single hulled board? 

It reminds me a bit of a pair of waterskis held rigidly together, with a fin poking down...

I have a very light 9.5 mtr rig, which is bigger than a moth.

I will also use my variable luff curve invention from a couple of years back, a 7 mtr I managed to get through the
course in a 48 knot wind, but the board I was using back then was slow.
There's a bit about it here
it's good for 31.5 knots on an old dog of a board.

Anyway we can talk all we like, the proofs in the pudding, but it'll be fun using stuff I've built myself, I'm usually
totally useless at making things, i can design them, but make them happen.. no chance.

looks like it would be quite interesting to watch
good luck with it Graeme, remember to get some video of it moving.

Ross: seeing as it will take a windsurf rig im sure it will be able to carry a silly amount of sail area, right down to the damn right small in a blow

How much sail is it going to be carrying?

The weed fin was an idea I'd had a while back to reduce drag, I was going
originally without a fin, then I had this idea for a fin'wheel' then given so
much experimentation best to prove one thing at a time.

Weed fins are foiled at that angle so you're not dragging the foil by
sweeping it back.

Straps and pads not in place yet, wanted to sail it first, get a feel for
where I'll need to put them..

No need to steer it really, speed sailors just blast down a straight course,
get off the other end, turn their board around and sail back, no need to
even gybe.
