    Transat Jacques Vabre

    On the start line of the Transat Jacques Vabre on the 27th of October 2019 most of the boats are relying on their Watt&Sea hydrogenerator to optimize their energy production. Good luck to each skipper !
  • Mini Transat departure in La Rochelle

    Mini Transat departure in La Rochelle

    Marie Gendron (Mini 930 "SNCF-Cassiopeia ») and Vincent Lancien (Mini 679 « Roll my chicken ») trusted us at the Mini Transat departure in La Rochelle and both left equipped with a 300W Watt&Sea custom hydrogenerator. The result is more than positive, since they have completed a first leg full of energy ! So much so that on the pontoons of Las Palmas de Gran Canaria, several competitors in energy debt on this first leg, are struggling to equip their boat with a Watt&Sea hydrogenerator before the second start on November 2 !
