Blue Technology designed the Liberty to maximize wind harvest, minimize frictional resistance from the air and sea, and eliminate the use of ballast water for stability. The result: a carbon fiber trimaran design emblematic of the sailboats competing in America’s Cup. The main power source of the Liberty is the wind. The average wind speed on the world’s oceans is around 7 m/s, which provides enough power for this ship to reach speeds of 18-22 knots. Since wind force is proportional to the cube of wind speed, wind speeds of 14 m/s increase the power output by a factor of eight. Traditionally, winds of this speed cannot be harnessed by sailboats due to stability concerns. The Liberty’s 55-meter wide trimaran hull, however, provides enough stability for the Liberty to safely operate even at very high windspeeds.
