초록
Planing crafts were specifically designed to achieve relatively high speeds on the water. When a planingcraft is running at high speed, dynamic pressure on the bottom makes the boat rise on the surface of the water. Thisreduces the area of the sinking surface of the boat to increase air resistance. Air resistance means the resistance thatoccurs when the hull and deck house over the surface of the water come in contact with the air current. In this paper, wecarried out a CFD numerical analysis to find optimal deck houses that decreased air-resistance on the water whenplaning crafts are running at high speed. We finally developed the deck house shape of high-speed planing crafts thatoptimally decreased air resistance.
Abstract
Planing crafts were specifically designed to achieve relatively high speeds on the water.

Air resistance means the resistance thatoccurs when the hull and deck house over the surface of the water come in contact with the air current. In this paper, wecarried out a CFD numerical analysis to find optimal deck houses that decreased air-resistance on the water whenplaning crafts are running at high speed. We finally developed the deck house shape of high-speed planing crafts thatoptimally decreased air resistance.
