A projection or addition to the side or bottom of the boat to help stabilize or provide lift. For straight-out speed on the water, not much can match a three-point hydro. In fact the majority of today's high speed boat records have been set by hydros. The two sponsons or "runners" provide stability at high speeds, while air rushing under the tunnel provides lift and a cushion of air. Little, if any, of the aft end of the boat is in the water. At speed the boat will ride on the two sponsons and the propeller. PICKLEFORK is a three-point hydroplane.
