Gordon Baker developed and tested Monitor in the 1950s.

Foiling monohull speed. The sailing boats beam is reduced to a minimum and the forward section was designed to be more aero-hydrodynamic this boat is truly built for speed. First tests of our one design foiling monohull spotted last week at Lake Garda Italy. One reason for the J24s popularity when it was widely introduced in 1977 is that the hull design was such that it regularly went faster than larger boats.

The GC32 is a 10m long by 6m wide foiling catamaran created through the collaboration of Laurent Lenne Dr Martin Fischer Head of Design at the Groupama Team France Americas Cup team and Premier Composite Technologies. 1950s Foiling Sailboat Monitor. As Team New Zealand launched its AC75 this morning the teams chief executive Grant Dalton talked about the boats intricate design - specifically how fast the foiling monohull can go.

Each team is limited to two full-sized 75-ft 23-m boats but may also build test craft up to 39 ft 12 m long for additional on-water testing. 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. Top speed was reported at over 30 knots with some reports claiming 40 knots.

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. Other factors are considered such as displacement and sail area but waterline length is where the boats base speed is established in a monohull. Monitor could get up on the foils in about 13 knots of wind and sail at about twice the true wind speed.

Hull shape will affect this though. British Moth and foiling aficionado Adam May got hold of an old Optimist and he. 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.

Fitted with T-foil rudders and J-shaped daggerboards the GC32 can reach speeds of up to 40 knots. The rules specify a monohull with soft sails but with canted T-wing hydrofoils on both sides. The boat holds the current speed record of 385 knots.
