ABSTRACT:
A pontoon boat comprising elongated flotation units of generally circular cross-section positioned in spaced-apart parallel relationship with each of the flotation units having planing fins extending longitudinally of the inboard and outboard sides of the flotation units near the bottom thereof to cause the pontoon boat to readily hydroplane. A wedge-shaped fin is provided on the underside of the outboard planing fins near the bow section to provide additional lift when turning at high speeds to improve control and stability on turns.
