Marine vessel control system, marine vessel propulsion system, and marine vessel

A marine vessel propulsion system comprising:

• at least one marine vessel propulsion device;
• a control unit including a main output section arranged to output marine vessel maneuvering control information including starting information of the at least one marine vessel propulsion device, and a sub output section arranged to output backup information including the starting information of the at least one marine vessel propulsion device;
• a first communication bus connected to the at least one marine vessel propulsion device and the control unit, and arranged to transmit the marine vessel maneuvering control information, output from the main output section, to the at least one marine vessel propulsion device;
• a second communication bus connected to the at least one marine vessel propulsion device and the control unit, and arranged to transmit the backup information, output from the sub output section, to the at least one marine vessel propulsion device;
• and
• an auxiliary device connected to the second communication bus, and arranged to execute communication, related to auxiliary information other than the marine vessel maneuvering control information, with at least one of the at least one marine vessel propulsion device and the control unit via the second communication bus.

A marine vessel comprising:

• a hull;
• at least one marine vessel propulsion device attached to the hull;
• a control unit including a main output section arranged to output marine vessel maneuvering control information including starting information of the at least one marine vessel propulsion device, and a sub output section arranged to output backup information including the starting information of the at least one marine vessel propulsion device;
• a first communication bus connected to the at least one marine vessel propulsion device and the control unit, and arranged to transmit the marine vessel maneuvering control information, output from the main output section, to the at least one marine vessel propulsion device;
• a second communication bus connected to the at least one marine vessel propulsion device and the control unit, and arranged to transmit the backup information, output from the sub output section, to the at least one marine vessel propulsion device;
• and
• an auxiliary device connected to the second communication bus, and arranged to execute communication, related to auxiliary information other than the marine vessel maneuvering control information, with at least one of the at least one marine vessel propulsion device and the control unit via the second communication bus.
