Fastest sailing boat in the world with a speed record of 5136 knots.

Hydrofoil sailboat speed. Discussion in Hydrodynamics and Aerodynamics started by revintage Sep 23 2018. It is short so potential hull speed is low 8ft long. Did this basic calculator based on Ray Vellingas metric approximation L 406 X V2 X S X Cl.

The complexity of the hydrofoil boat arises from the fact that it sails. Our 8ft boat is absolutely sub optimal as a foil stabilised boat. Therefore the hull comes out of the water.

And several sailing foiler patents began appearing in the 1950s. As the boats speed increases the hydrofoils create lift. On a cold day in October 1991 a team from the Massachusetts Institute of Technology MIT led by physicist Mark Drela set a record for the fastest human-powered water craft.

Italian Enrico Forlanini began experimenting with foils in 1898. The generally accepted maximum before meeting the cavitation barrier is about 42 The recommended top speed of the Rave is 30 knots. Sensors The BAR team uses 190 sensors and four video cameras in order to monitor their boat.

Such an ultimate sailing craft might well be equipped with a ladder foil arrangement having a supercavitating foil as its bottom rung. This video beneath says quite a lot about how fast you can make a hydrofoil. Overview of comparison sailing the hydrofoiled boat against the larger Oz Goose This is not necessarily a question of speed though it is nice to get.

New theoretical limits imposed by cavitation over the hydrofoil wings bubbles over the wings. The record is 5136 knots which is 9512 kmh and that is insane for a sailing boat. Alexander Graham Bells HD-4 Hydrodrome flew on Bras d Or Lake at 70 mph in 1919.
