An improved, planning pontoon boat has first and second spaced apart, elongated pontoons which exhibit a bow end and a stern end relative to the boat. A lower surface of each of the pontoons exhibits two intersecting planar members which terminate adjacent to respective elongated lift pads for the purpose of providing improved planing characteristics for the pontoons. The lift pads are each formed of intersecting concave surfaces. The lift pads extend radially from the pontoons and are located adjacent to the intersection of the planar surfaces and an upper curved surface of the pontoon. An elongated keel extends along the bottom of each of the pontoons, in the region where the planar elements intersect. The keel extends parallel to the lift pads.
