WATERCRAFT MANEUVERING SYSTEM, AND WATERCRAFT INCLUDING THE WATERCRAFT MANEUVERING SYSTEM

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.

Description

Claims

1. A watercraft maneuvering system comprising: an operator fob usable by an operator of a watercraft;a watercraft maneuvering input on the watercraft operable by the operator 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; anda disembarkation sensor to detect disembarkation of the operator carrying the operator fob from the watercraft; whereinthe 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 carrying the operator fob has disembarked from the watercraft irrespective of the operation of the watercraft maneuvering input.

2. The watercraft maneuvering system according to claim 1, wherein the propulsion system includes an engine, a propeller to be driven by the engine, and a clutch provided in a power transmission path between the engine and the propeller; andthe propulsive force non-generation state of the propulsion system includes an operation state in which the clutch is in a disengaged state.

3. The watercraft maneuvering system according to claim 2, wherein the controller is configured or programmed to perform the operation state maintaining control operation if the disembarkation sensor detects that the operator carrying the operator fob has disembarked from the watercraft when the engine is in operation and the clutch is in the disengaged state.

4. The watercraft maneuvering system according to claim 1, wherein the disembarkation sensor includes a communicator to wirelessly communicate with the operator fob, and to detect whether or not the operator has disembarked from the watercraft based on a state of communication between the communicator and the operator fob.

5. The watercraft maneuvering system according to claim 1, further comprising: an overboard sensor to detect an operator overboard event when the operator falls overboard from the watercraft; whereinwhen the overboard sensor detects the operator overboard event, the controller is configured or programmed not to perform the operation state maintaining control operation but to perform a propulsive force nullifying control operation to nullify the propulsive force of the propulsion system.

6. The watercraft maneuvering system according to claim 5, wherein the disembarkation sensor and the overboard sensor share a communicator to wirelessly communicate with the operator fob, and are operable to distinguish between the operator overboard event and the disembarkation of the operator from the watercraft based on a state of communication between the communicator and the operator fob.

7. The watercraft maneuvering system according to claim 1, further comprising a cancellation switch to cancel the operation state maintaining control operation.

8. A watercraft maneuvering system comprising: a watercraft maneuvering input on a watercraft and operable by an operator of the watercraft to command generation of a propulsive force;a controller provided on the watercraft and configured or programmed to control operation of a propulsion system of the watercraft according to an operation of the watercraft maneuvering input; anda disembarkation sensor to detect disembarkation of the operator from the watercraft; whereinthe 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.

9. A watercraft comprising: a hull;a propulsion system provided on the hull; andthe watercraft maneuvering system according to claim 1.

10. A watercraft comprising: a hull;a propulsion system provided on the hull; andthe watercraft maneuvering system according to claim 8.
