A comparison study on the deck house shape of high speed planing crafts for air resistance reduction

ABSTRACT: Planing crafts were specifically designed to achieve relatively high speeds on the water. When a planing craft is running at high speed, dynamic pressure on the bottom makes the boat rise on the surface of the water. This reduces the area of the sinking surface of the boat to increase air...
