Think about it this way. If the generator is 100% efficient, then to
generate 746 watts, one horsepower must be provided. Imagine a dinghy
with a one hp engine pulling your boat backwards and you get a sense
of practicality. In practice, two or three hp is probably closer to
what the effect might be.

So there is plainly an upper limit to the amount of power a towed
generator can realistically provide to a small sailboat.

Small sailboat? So, probably a 12 volt battery..
746 watts is 62 amps at 12 volts-far too much for your battery.
Certainly there is an upper limit to the power you can get, but there should
be no problem in getting quite enough to power up anything you have aboard a
small sailboat.
