Heaving to

In sailing, heaving to (to heave to and to be hove to) is a way of slowing a sailing vessel's forward progress, as well as fixing the helm and sail positions so that the vessel does not have to be steered. It is commonly used for a "break"; this may be to wait for the tide before proceeding, or to wait out a strong or contrary wind. For a solo or shorthanded sailor it can provide time to go below deck, to attend to issues elsewhere on the boat or to take a meal break. Heaving to can make reefing a lot easier, especially in traditional vessels with several sails. It is also used as a storm tactic. A sailing vessel that is hove to is still, for the purposes of the collision regulations, on a defined tack. Therefore, unless other considerations dictate differently, it is helpful to heave to on the starboard tack, in order to be a "stand-on vessel", as per the regulations. The term is also used in the context of vessels under power and refers to bringing the vessel to a complete stop. For example, in waters over which the United States has jurisdiction the Coast Guard may, under 14 U.S.C. §522, demand that a boat "heave to" in order to enforce federal laws.
