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.
iQFoil is a windsurfing class selected by World Sailing to replace the RS:X for the 2024 Summer Olympics. [2] The discipline has similarities to Formula Windsurfing, however a notable difference is that sailors only use one sail. The sail size is 9m² for the men and 8m² for the women. [3]
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.
Windfoiling (or foil windsurfing) is a surface water sport that is the hydrofoiling evolution of windsurfing, as well as typical sailing boats and sailing hydrofoils. It uses similar equipment to windsurfing with a normal or slightly evolved rig on a normal or specialist foil board.
Unlike fixed mast sail a boat, windsurfing is rudderless and uses the universal joint to allow steering the board with the sail alone. Jibing is done at full speed (a so-called "carve jibe", "power jibe" or "planing jibe"), whereby the rider turns downwind by leaning the sail forward, sheeting and applying pressure to the inside rail.
Jim Drake's wing invention 1982. The history of wing foiling, or simply "winging" begins with the invention of pre-hydrofoil technology wing surfing dating back to 1981, when aeronautical engineer Jim Drake, who also invented windsurfing, [4] and Uli Stanciu, European windsurfing pioneer, together invented and patented the world's first wing.

Windsurfer rig – When sailors of windsurfers jibe, they use techniques like the carve jibe and the duck jibe or sail back winded then push the leech through the eye of the wind as in an upwind 360 or after ducking the sail to back winded. The carve jibe allows the sail to pivot away from the wind as the board is turned with the wind passing ...
18ft Skiff in Kiel Harbor. 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.
