Navigation resistance of the ship?
Author：
Ship sailing resistance refers to the force acting on the hull to prevent the movement of the ship when the ship is sailing. Including air resistance and water resistance. In general civil ships, the air resistance is only 2% to 4% of the total resistance. Water resistance consists of two parts, one is the additional resistance of the rudder, shaft and keel that protrudes beyond the hull; the other is the resistance of the hull itself, that is, the naked resistance. The additional resistance generally only accounts for 3%~10% of the total resistance
