Safety, comfort and respect of the environment
Watt&Sea’s aim is to conceive, manufacture and market energy systems for marine use, to help reduce the impact on our planet and to bring more freedom, comfort and safety to the yachtsmen: this is the daily motivation for the team of Watt&Sea. The innovations of our hydro generators are the result of intensive work and research.
To provide its advantages to a large number of yachtsmen in the world is a strong mission and a challenge for the company and its team. At sea a sailing boat is like an autonomous cell of life: when released from the mooring, the boat is totally isolated. The production of energy on board then becomes crucial to guarantee navigation in full safety and freedom. Environmental issues and complex electrical equipments on board sailing boats requires better solutions to provide energy on board. Watt&Sea hydro generator bring the power of energy independence to cruising or racing, with respect for the environment.

Watt&Sea hydro generators

An old concept but a new performance: famous sailors Eric Tabarly and Philippe Poupon imagined and tested this concept well before Watt&Sea. The principle is simple: using the speed of the sailing boat to turn an immersed propeller and produce electricity: like a dynamo of a bicycle rubbing on the wheel, the propeller turns and produced electricity.
An innovation : Watt & Sea created a hydro generator interdependent of the boat, considerably improve its output, performances, reliability and industrializes it. On the Cruising model, the first amps are generated from 3 knots (a little less than 6 km/h).
