Carbon RACING Hydrogenerator

  • Carbon Racing

    The Racing Carbon hydrogenerator has been tested for the first time during the Vendée Globe 2008. Continuously improved, this model is honoured to be chosen to outfit the 2017 Volvo Ocean Race fleet.

    The Racing Carbon hydrogenerator is designed for high or very high speed sailing boats. It is equipped with a controlled pitch propeller, functionning electronically with an hydraulic pump. The propeller pitch is setting automatically depending on the boat speed, ensuring a minimal drag and an optimal energy output. This model is functional for a speed range from 5 to 30 knots (Multihulls, Class40, Imoca…). The Racing Carbon hydrogenerator has satisfied the energy needs for 96 % of the 2016 Vendée Globe fleet.

    Variable pitch propeller

    The automatically controlled pitch propeller allows to use the hydrogenerator in a large range of speeds from 5 to 30 knots with a minimal drag.

    The feathered position of the blades facilitates the immersion.

    For specific performances, we can design custom blades.
