Points of sail and approximate apparent wind for a conventional sailboat on starboard tack. A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface. The principal points of sail roughly correspond to 45° segments of a circle, starting with 0° directly into the wind.
A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or ...
All sailing craft reach a constant forward velocity (V B) for a given true wind velocity (V T) and point of sail. The craft's point of sail affects its velocity for a given true wind velocity. Conventional sailing craft cannot derive power from the wind in a "no-go" zone that is approximately 40° to 50° away from the true wind, depending on ...
The top of a triangular sail, the head, is raised by a halyard, The forward lower corner of the sail, the tack, is shackled to a fixed point on the boat in a manner to allow pivoting about that point—either on a mast, e.g. for a mainsail, or on the deck, e.g. for a jib or staysail.
Literally, the word pinisi refers to a type of rigging (the configuration of masts, sails and ropes ('lines')) of Indonesian sailing vessels.A pinisi carries seven to eight sails on two masts, arranged like a gaff-ketch with what is called 'standing gaffs' — i.e., unlike most Western ships using such a rig, the two main sails are not opened by raising the spars they are attached to, but the ...
Since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. Tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and significantly delayed long voyages. The early European ...
