The Outremer 4.zero is the first series cruising electric catamaran. Without fossil fuel on board (diesel or gas), it can be used without any CO2 emissions. Designed for long distance sailing, its ability to produce energy by the engines when the boat is sailing gives it autonomy without limits other than the weather. This innovation created for the preservation of the environment allows the sailor to navigate with favorable winds, thus reconnecting with nature and his boat, whilst maintaining the comfort and safety necessary for a family trip.
