Abstract: A marine vessel portable device registration system includes portable devices and a controller. A registered portable device transmits a specific wireless signal based on an input operation on a portable device operator. The controller is configured or programmed to receive the specific wireless signal from the registered portable device, and perform a control to authenticate and register an unregistered portable device as a new registered portable device based on having received a wireless signal from the unregistered portable device.

Abstract: An overboard detection system includes a fob to be carried by a user on a watercraft, an overboard sensor to detect a user overboard event when the user carrying the fob falls overboard, and a communicator on the watercraft to wirelessly communicate with the fob and to transmit a rescue intention notification indicating a rescue intention to the fob carried by the user involved in the overboard event. The fob includes a transmitter operable to provide the rescue intention notification to the overboard user upon reception of the rescue intention notification.

Abstract: A watercraft maneuvering system includes a watercraft maneuvering input on a watercraft operable by an operator of the watercraft so as to command generation of a propulsive force, a controller on the watercraft and configured or programmed to control operation of a propulsion system of the watercraft according to the operation of the watercraft maneuvering input, and a disembarkation sensor to detect disembarkation of the operator from the watercraft. The controller is configured or programmed to perform an operation state maintaining control operation to maintain the propulsion system in a propulsive force non-generation state when the disembarkation sensor detects that the operator has disembarked from the watercraft irrespective of the operation of the watercraft maneuvering input.

Abstract: A watercraft maneuvering system includes an overboard sensor to detect an operator overboard event when a watercraft operator falls overboard from a watercraft, and a controller provided on the watercraft and configured or programmed to control a propulsion system of the watercraft. The controller is configured or programmed to perform a fixed point holding control operation to control the propulsion system to maintain a fixed position of the watercraft when the overboard sensor detects the operator overboard event. The overboard sensor is provided on the watercraft, and includes a communicator that wirelessly communicates with an operator fob to be carried by the operator. The operator sensor may detect the operator overboard event based on a state of communication between the operator fob and the communicator.

Abstract: A marine vessel maneuvering apparatus performs maneuvering of a marine vessel by wireless communication, and includes an operator to move the marine vessel in an operating direction of the operator, a recorder to record location information of a place where fishing is performed using the marine vessel that is moved by operating the operator, and a controller connected to at least the recorder.

Abstract: A control system of a marine vessel includes a portable device and a receiving device. The portable device transmits a switch control signal to the receiving device based on an input operation. The control system of the marine vessel performs an authentication control process based on an authentication signal from the portable device, and controls opening or closing of a current path based on the switch control signal from the portable device.

Abstract: A marine propulsion device controller includes a main operator that starts engines of all propulsion devices collectively with a simple operation and increases the degree of freedom of layout on a panel on which the main operator is disposed. The main operator is provided in common for all of the propulsion devices. The main operator receives a first operation and a second operation consecutively after receiving the first operation. All remote control ECUs are activated in response to receiving the first operation. The main operator outputs a collective start command to simultaneously start all the engines of the propulsion devices in response to receiving the second operation. Each remote control ECU starts the corresponding engine based on the collective start command.
