Hydrofoil sailboat top speed. And several sailing foiler patents began appearing in the 1950s. In 2009 Hydroptere broke the outright world speed record by hitting 5286 knots and subsequently setting a nautical mile record of 5017 knots. The best hydrofoils reach about 22 USS Tucumcari about 183 some hovercraft about 263 SES Corsair about 2254 the demonstrator craft Thunder Child II with 26176 at top speed and 24117 at 45 knots cruising speed and the Alpha Yacht with 28765 to name a few examples.

Alexander Graham Bells HD-4 Hydrodrome flew on Bras d Or Lake at 70 mph in 1919. With the introduction of the hydrofoil speed demons have a new tool in their arsenal to play with and new world records to break. Such a section is shown in Fig.

New theoretical limits imposed by cavitation over the hydrofoil wings bubbles over the wings. Pick up your outboard Hydrofoil here. Speed Hydrofoils can enable speeds of up to 100kph three times that of the wind.

Stable flight attitude allows pushing hard so in good condtions iFLY reaches high boat speed beyond 30 knots in a controllable way. As the boats speed increases the hydrofoils create lift. The speed at which cavitation begins lies in the 40 knots plus range for most hydrofoils and so does not concern us other than for a large sailing speed record machine.

This is not necessarily a question of speed though it is nice to get. The boat holds the current speed record of 385 knots. At a certain speed the lift produced by the hydrofoils equals the sum of of the boat and cargo weights.

ONE OF THE THINGS YOU HAVE TO EXPERIENCE TO FEEL IT. In 1906 his 1-ton 60 hp foiler reached 425 mph. DID YOU KNOW The first hydrofoil was built in 1906 by Italian Enrico Forlanini enabling him to.
