Full Electric: Electric Motor with Energy Storage

This full electric propulsion system uses a single electric motor per drivetrain. It’s most suitable for short-trip vessels (e.g., ferries, pilot boats, inland waterways vessels, harbor vessels, small yachts, and fish-farming vessels) with sufficient shore time to charge batteries between excursions, and for those operating in restricted areas and zero-emission zones.
