Watt&Sea Hydrogenerators produce power with a water turbine housed in a computer-optimized hydrodynamic design. Once a sailboat has left the docks, is totally isolated from utility (grid) power. The production of energy on any boat is crucial to powering communications, navigation lighting and other energy consuming devices. Operating diesel engines and generators are costly, noisy and are environmentally unsanitary. The clean energy solution is the Watt&Sea Hydrogenerator, which easily deploys off the back of the cruising or racing vessel efficiently generating power for energy independence.
