Remember that sail/MV that J. Cousteau's son had?
It had 3 big poles for sails.

How about fixed wing Sailing vessels like that American cups cat,
Seems I remember seeing a few pictures of boats retro fitted with
surplus airplane wings. Anyone rremember seeing one? Pictures?

The other day one of thoses kite surfers were tearing up the lake,
running upwind quite fast. Wonder when the first kite sailing boat
will hit the market?

I have a surplus 75' canopy silk parachute I need to do something
with. I was planning on cutting it in 3 equal sections for down wind
chutes, but it would be cool if I could fly it on a teather. It was
made for dropping jeeps.

Can you think of any unique wind powered boats... besides the fake
windmill boat that you have ever seen?

They weren't "poles," they were Flettner rotors.

Yep.

I don't think a kite sail is going to work anywhere near as well on a
heavy boat. BTW most kite sailer sail on broad reaches. They don't go
upwind very well.

You could fly it on a tether, if you cut some vents in one side and
arrange so that it stays the same side up. Otherwise it will flop down
into the water. Maybe you could fly it from your mast head, is that high
enough to keep it from dragging?

I don't think parachute silk is going to make a very good sail. But hey,
it's paid for.

Are you saying there have never been windmill powered boats? If so,
you're quite wrong.

Thanks, I found a german sight with lots of information and pictures.

Wonder why it is not more widely used. Must not be cost effective.
