However I might deviate slightly from that contention and fit a rig to one

of our CS power cat designs. The only real advantages of this would occur if
youwanted to go a bit faster  than the sail boat hull was capable of.

If you are still determined to "boldly go where no man has gone before" you
could go where we went in 1992 and fit a wind turbine driving in the water
propellers [see web site- the "Revolution"]. However today I would go and

buy a reasonably substantial "off the shelf" wind turbine electric generator
and fit it to one of our CS hulled stock power cat designs. This would drive
a

couple of electric motors in the hulls.

Incidentally, despite what several physicists have to say on the internet,

the Revolution would proceed directly to windward.

PS: Malcolm, I also like your hull shape with an alternative 'wind
propulsion'
