IMOCA 60 Malizia II The boat is designed by.

Foiling monohull speed. Despite this the desired low takeoff speed was a real challenge. Top speed was reported at over 30 knots with some reports claiming 40 knots. Despite this the desired low takeoff speed was a real challenge.

British Moth and foiling aficionado Adam May got hold of an old Optimist and he. What they created was a performance design using the latest technology for a monohull one-design class with a sleek hull that already sails fast in conventional mode without foils. With the AC75 the righting moment stays constant as you go through the windspeed range - so in the mid-windspeed range once you are foiling in 9-15kts of breeze there is definitely the potential to be quicker than an AC50.

Monitor could get up on the foils in about 13 knots of wind and sail at about twice the true wind speed. Laureano Marquinez explains. The emphasis was on safety and slow take-off speed so that this boat can foil even at low true wind speeds.

SYZ Co Swiss private banking group SYZ Co sponsored this foiling multihullwhich was launched in 2009 to capture the speed records on Lake Geneva as well as with the aim of winning races. At 40 knots cavitation would probably have set in. The rules specify a monohull with soft sails but with canted T-wing hydrofoils on both sides.

Later designs like the Melges 24 were even faster. The boat holds the current speed record of 385 knots. Gordon Baker developed and tested Monitor in the 1950s.

1950s Foiling Sailboat Monitor. Hull shape will affect this though. The team only had a few months to design Boat 1 so fully relied on simulation to compare the performance of different foils hulls and sail setups.
