some of the bigger ones i have seen on ebay claim that they can be used that
way. some manufacturers build theirs purposely for this, and have a hybrid
mode too which looks interesting. the bigger ones i have seen go up to an
equivallent of 48hp, but they're not cheap and still require a seprate sahft
and prop. they list full specs on what sort of speeds you have to be
sailing at to get full current from them.

the hybrid drive looks the most interesting to me.

I have often wondered this too. I suspect that to optimize as a
generator, you'd want a different prop (bigger, lower pitch?)
