Integrated over the sailing craft, the total aerodynamic force (F T) is located at the centre of effort (CE), which is a function of the design and adjustment of the sails on a sailing craft. Similarly, the total hydrodynamic force ( F l ) is located at the centre of lateral resistance ( CLR ), which is a function of the design of the hull and ...
Sailing relies on the physics of sails as they derive power from the wind, generating both lift and drag. On a given course, the sails are set to an angle that optimizes the development of wind power, as determined by the apparent wind , which is the wind as sensed from a moving vessel.
A sailing craft running more downwind than a broad reach cannot attain a speed faster than the true wind. However, higher-performance sailing craft achieve a higher velocity made good downwind, by sailing on whatever broad reach is most efficient on that particular craft, and jibing as needed. The longer course is offset by the faster speed.
Spar (sailing) – pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include booms and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.
High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail.
Jibe – Basic sailing maneuver, where ship turns its stern through the wind Tacking (sailing) – A sailing maneuver Translation (physics) – Planar movement within a Euclidean space without rotation Pages displaying short descriptions of redirect targets
Sailing into the wind is a sailing expression that refers to a sail boat's ability to move forward despite being headed into (or very nearly into) the wind. A sailboat cannot make headway by sailing directly into the wind ( see "Discussion," below); the point of sail into the wind is called " close hauled ".
In sailing, apparent wind is the speed and direction of wind indicated by a wind instrument on a moving craft (on water, land or ice) in undisturbed air. It is composed of the combined speeds and directions of the craft and wind observed by a stationary wind instrument—the true wind. A true wind coming from the bow increases the apparent wind ...
