SAILING VESSELS

摘要

A sailing vessel having a mast upstanding from the hull and connected to be free to tilt on the hull about a longitudinal axis, and a keel depending the hull and also connected to be free to tilt on the hull about a longitudinal axis, the mast and keel being interconnected to cause rotation about the axes in the same sense, the keel having sufficient weight to hold the mast upright but allowing it to deflect leeward about the hull under wind pressure, the keel balancing the leeward deflection by tilt to windward without necessarily deflecting the hull. 1.
