Electric powered ferry has been designed to accommodate the requirements of an electric drive system. As a catamaran with two slim hulls, it offers less resistance in the water than a conventional vessel. The vessel’s shape itself was designed to minimize resistance in the water. In order to reduce the ferry’s weight, the designers have made the hulls much lighter than usual, using aluminum instead of conventionally-used steel. Furthermore, the hulls are made of aluminum instead of steel, which is conventionally used. Rather than a diesel engine, the ferry is equipped with electric motors to drive the ship's two screws. The 10-metric-ton battery powers two electric motors, and can be recharged in only 10 minutes. The batteries will recharge the ferry during its turnaround and then themselves, using the power from the local grid.
