Extreme 40
The Extreme 40 is a class of sailing catamaran created by TornadoSport and designed by Yves Loday. 40 feet long and constructed of carbon fibre. They have a top speed of about 40 knots (~46 mph, 74 km/h) and can sail at about 35 knots in 20-25 knots of wind. [1] The first extreme 40 was launched in 2005. They are sailed in the Extreme Sailing Series, formerly known as the iShares Cup. Extreme 40's are essentially a scaled up version of the Tornado sailboat used in The Olympics. [2]
