Abstract A hydroplane boat adapted to have increased fore and aft and lateral stability at minimal planing speeds having a substantially V-shaped hull with a slot positioned at approximately amidships extending outwardly from the keel wherein at said speeds said slot becomes submerged and forming two distinct leading edges aft of the slot to thereby lift the stern and prevent the bow from rising to an unstable position. Mounted about the bow of the hull to the position of the slot is a sponson having a keel substantially parallel to the keel of the hull and a shelf portion positioned between the hull and the sponsons, the shelf portion extending to the stern of the boat whereby upon either sponson becoming submerged a strong lifting action is imparted to that side of the boat tending to right the boat.
