Just for you, Grumpf

Nice but...

I'd like a flared 'chisel' deck with some volume to stop nose dives and
provide platform for me to swivel my pole in light weather when I can't
make downwind 'angle' speeds.

Either a stepped hull (since we're in dvelopment territory here) or a chine
design I shall have to give you, borrowed from a revolutionary in its day
powerboat I once raced in the seventies, it was 15% more efficient by
sweeping the chine ends in which provided a step of sorts and reduced
the wetted area the faster it went. Proved a bit to efficient for the engine
we had back then, but that's another story, i reckon sail power would
work really well, it also self levelled.

Anyone reading this may recall the Bo Oldenburg design it featured on
Tomorrows world in 1975, we built one in Kevlar (First boat ever built
anywhere in the world in the damn stuff, blunted five diamond cutters
and fell in half the first wave we took because the kevlar weave supplied
by Dupont was so watertight it didn't accept the resin, you can thank me
for Kevlar S Glass and the other variations that were to come later.)

Thanks for that peaky, nice looker, but wouldn't suit our water, that's
what i like about the Blaze hull, it'll take a good sea, you can see that just
by looking at it, it also has a potentially really fast parabolic rocker which
would release well if the nose got a good kite lifting it I reckon..

Yes that's my current thinking as well, but there may be other alternatives in
the near future and there was just one other avenue I haven't explored yet
based on the Solution. I haven't spoken to them yet but I'd reasoned it might
be worth posing the question as soon as my busy period finishes which
should be by close of business today.

You've claimed to have sailed an Iso, haven't you? Blaze's hull shape is pretty much that, but smaller. Close enough to get a feel for what you reckon, I'd have thought?

Thanks. To be honest, it is just placed by eye in these drawings - I only spent about an hour knocking it up.  I will do some more proper design on it over the weekend, and see where the board ends up then.

I think there is a large number of people who don't want to trapeze helm at all - either because it is a skill too far, or the water is too restricted, because they like the pain of hiking. 

Originally posted by RS400atC The board looks a long way forward to me.

I assumed that was to do with the fact it swings back and if the start point is
too far back the tip inteferes with the rudder when it's pivoted back.
