Hydroplanes that lift out of the water to ride on 2 or 3 planing points have featured since Bluebird K7.

But this causes another problem because air between the water surface and the bottom of the hull compresses before it is ejected at the rear.

Managing Aerodynamic drag (the bits above the water) and hydrodynamic drag (the bits in the water) and especially the complex area between the two is hugely complicated if your goal is a craft that is controllable as well as fast.

Wings under Water – or hydrofoils – lift the boat above the surface, clear of any surface disturbances and reducing drag.
