Re: fastest kayak?

See CLC's, and two other posts. Your definition is almost correct.

In fact, "hull speed" is simply the speed at which bow and stern waves constructively interfere.

It is true enough to say that the incremental power to achieve an incremental increase in speed goes up sharply as you approach hull speed. But that ignores the other half of the equation, that in an ultralight fast boat (ie, a boat whose planing speed is higher than its hull speed) the incremental power goes DOWN after you pass hull speed! (At least until viscous drag takes over, or planing occurs. Remember that viscous drag is increasing very rapidly with speed.)
