A sailing hydrofoil, hydrofoil sailboat, or hydrosail is a sailboat with wing-like foils mounted under the hull. As the craft increases its speed the hydrofoils lift the hull up and out of the water, greatly reducing wetted area, resulting in decreased drag and increased speed. A sailing hydrofoil can achieve speeds exceeding double and in some ...
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.
A human-powered hydrofoil is a small hydrofoil watercraft propelled entirely by the muscle power of its operator(s). [1] ... greatly reducing the drag force. [1]
She has been the resident drag queen for Propaganda and Fuel in Hull. [5] Miss Naomi Carter competed on series 5 of RuPaul's Drag Race UK. She was the first contestant of Gambian heritage to compete on any Drag Race franchise. [6] She had been doing drag for approximately five years, [7] and was cast after applying to be on the show three times ...
The JetCycle hydrofoil lets you glide over the water while reclining in a kayak-type boat. By pedaling, the JetCycle rises up to eliminate drag from the water, pushing you faster and easier than ...
The Moth is a small development class of sailing dinghy.Originally a small, fast home-built sailing boat designed to plane, since 2000 it has become an expensive and largely commercially produced boat designed to hydroplane on foils though many are still built at home, typically at much lower cost.
The hull (below the water) and the sailing rig (above the water) each have drag angle with respect to the medium flowing past them (water or air), they are λ and α m in the accompanying diagram. The sum of those two drag angles are equal to β, the angle between the apparent wind and the course sailed (β = λ + α m). This theorem applies ...
The Flyak has two hydrofoil fins below the surface of the water to create lift.At high speeds the entire hull is lifted 15 cm (5.9 in) from the water, reducing the drag and allows greater speeds – reportedly more than twice the speed of a conventional kayak.
