Equipped with contra-rotating propeller system, the ISHIN-II will have a diesel engine and electric propulsion motor. The propellers will be aligned front to back and fitted with propeller boss cap fins.
The propellers will rotate in opposite directions to distribute the load of propelling the ship. The energy generated from front propeller rotation is absorbed by the rear propeller to increase efficiency. The system has been installed on over 1,700 vessels.
