Re: Can planing hulls exceed hull speed upwind?

Both multihulls and and some sportboats are capable of acting as semi-displacement boats upwind. In other words, they are designed to miimize the size of their bow and quarter waves and so can achieve speeds which exceed their theoretical hull speed. But besides hull speed is not an absolute brick wall, it is only a point where dynamic drag rises very steeply.
