Dennis,
That does look nice.
I'm partial to rigs on the leeward hull because I'd rather reduce my
windage as a hull flies instead of increasing it, and also to maximize
internal space in the windward hull. I'd also rather keep the windward
hull free of rig stress, particularly because of the wracking loads
that will be imposed by that long leeward hull.
However, once the boat is large enough, having the mast come through
the windward hull won't matter -- you'll have the room. You'll still
have to design for the rig and wave forces that now need to be
translated through the amas, but I imagine that can be done.
What you gain is a short leeward hull, which may make transporting
the boat easier, and also safer access to the rigs while sailing.
You can fit that on a trailer in 8.5'? Now THAT is impressive.
How is that done? By tilting the windward hull on its side and
storing the leeward hull in the "L" created by the windward hull and
the bridge deck? Would you design a trailer to do this, or rely on a
yard with a crane?
Also, how are you planning to deal with leeway resistance and
steering?
Regardless, it's great to see people pushing the envelope.

I'd like to do some races if I happen to land myself in a friendly island race. I don't have any intention of getting into races where competitors are getting points toward some championship or are willing to maliciously cut across my path to force a shunt. I wouldn't want to do any open ocean, multi-day races (TransPac, Bermuda, etc) I also want a con-da-frik'n-minium, so my weight will not be competitive. I ended up with a 60' (18.3m) lee hull. The accommodations drove the size more so than the outright speed. http://www.boatdesi gn.net/forums/ I enjoy the theoretical work using Michlet and now I'm tinkering with Flotilla thanks to Rick. Do I really think I'll see 30 knots? Nah! It doesn't even take into account rudder/daggerboard drag much less a dozen other things. I think I'd have the biggest Cheshire Cat grin you ever saw, if it touches 20. Beating a GunBoat in a race would be my biggest goal.multihulls/ search-prefect- proa-33468. html Dennis
