Tri-Plane Hull

This is a type of hull that uses three planing surfaces at one point in the length of the board. A plane is defined as a flat surface (no concave/convex) so a triplane takes the shape of a panel vee with a flat panel in the centre. The effect of this is a smaller surface area that comes in contact with the water and having sharp angles will help it transition from rail to rail. The smaller surface area hitting the water will allow the board to sink deeper into the wave to use more of its energy which will then transition into incredible trim and lift speed. For examples I have found the most defined tri planes on old wave jumpers (windsurfboards).
