Good explanation. Another way to think about it is with modern sails and hull design it's more like a wing. The sail above the water is the more obvious wing shape, and with some designs that use a centerboard or daggerboard that is like the other half of a wing turned on its side. With water having more drag than air, the centerboard is the continued wing shape under the water only shorter.

Equilibrium. Definitely a B movie. Call it a Matrix clone if you will, but that opening was an incredible experience in the theater.
