True wind (V T) is the same everywhere in the diagram, whereas boat velocity (V B) and apparent wind (V A) vary with point of sail. Forces on sails result from movement of air that interacts with sails and gives them motive power for sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and sail-powered land vehicles.
Diagram contrasting course made good to windward by tacking a schooner versus a square-rigged ship. Sailing vessels cannot sail directly into the wind. Instead, square-riggers must sail a course that is between 60° and 70° away from the wind direction [76] and fore-and aft vessels can typically sail no closer than 45°. [77]
A ship that depended on the wind for its motive power could not hope to ram. A sailing vessel could not ram unless it was running before a good breeze. In a light wind, the charge would be ineffective, and it could not be made at all from leeward. It could still board, and the Spanish did for long make it their main object to run their bow over ...
A polar diagram, or polar plot, is a graph that shows a sailboat's potential speed over a range of wind speeds and relative wind angles. [1] It normally consists of the right side of a line chart with the radius representing the yacht speed and the angle representing the wind direction blowing from top to bottom. Several lines are normally ...
Shore power or shore supply is the provision of shoreside electrical power to a ship at berth while its main and auxiliary engines are shut down. [1] While the term denotes shore as opposed to off-shore, it is sometimes applied to aircraft or land-based vehicles (such as campers, heavy trucks with sleeping compartments and tour buses), which may plug into grid power when parked for idle reduction.

Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
