  • Hybrid marine propulsion system
    Patent number: 12221198
    Abstract: A hybrid propulsion system for a marine vessel is described. The hybrid propulsion system includes a shaft coupled to a propeller, a planetary gear system configured to operate in a first configuration and a second configuration, and a motor-generator. The motor-generator is configured to selectively rotate with and provide torque to the shaft through the planetary gear system in the first configuration and to rotate independently from the shaft in the second configuration. The shaft extends from the propeller through the planetary gear system and the motor-generator to a torque producing device for the marine vessel.
