Easily get an idea of which GreenStar system that is right for your boat. Simply choose a straight shaft or a sail drive, the weight of the boat and a desired amount of batteries. The tool below will suggest a system and also approximate run times with the chosen configuration.

The calculated runtime is an estimation. Run time in reality also depends on factors such as shape of the hull, keel and propeller.
Runtime calculations are based on the use of our Deep Cycle AGM 100 Ah 12 V batteries.
Our batteries are carefully chosen to meet our demands on performance and run times and are therefor always included in a GreenStar electric propulsion system.
