Mark F,
Electric boating is all about efficiency to me, since electrons are a scarce resource out on the water. So I hear you asking, "how to go farther/faster on less".
I say more power (more sail), or less drag (clean hull, hull surfacing tech [ribblets, bubbles, or teflon anyone?], better propeller, lighter boat, hydrofoil).
But I've gone too far, since hydrofoils only benefit above 10 knots, which is out of bounds from your original question. But while on the subject, I personally hit 35 knots boat speed with < 25 knot winds on SF Bay when I had a Rave. See:
