Abstract
A marine vessel maneuvering system includes a jet propulsion device to jet a water current out from a jetting port and obtain a propulsive force from a recoil of the jetted water current, a handle to change a direction of the jetting port, a reverse bucket to open and close the jetting port, and a controller configured or programmed to change the direction of the jetting port in accordance with a rotation angle of the handle. In a state in which the reverse bucket covers at least a portion of the jetting port and when the rotation angle of the handle exceeds a first threshold, the controller is configured or programmed to execute a turning assist control to reduce an amount by which the reverse bucket covers the jetting port.
Claims20
A marine vessel maneuvering system comprising:
- a jet propulsion device to jet a water current out from a jetting port and obtain a propulsive force from a recoil of the jetted water current;
- a handle to change a direction of the jetting port;
- a reverse bucket to open and close the jetting port;
- and
- a controller programmed to change the direction of the jetting port in accordance with a rotation angle of the handle;
- wherein in a state in which the reverse bucket covers at least a portion of the jetting port, the rotation angle of the handle exceeds a first threshold, and the marine vessel moves forward, the controller is programmed to execute a turning assist control to reduce an amount by which the reverse bucket covers the jetting port.
A marine vessel maneuvering system comprising:
- a jet propulsion device to jet a water current out from a jetting port and obtain a propulsive force from a recoil of the jetted water current;
- a handle to change a direction of the jetting port;
- a reverse bucket to open and close the jetting port;
- and
- a controller programmed to change the direction of the jetting port in accordance with a rotation angle of the handle;
- wherein
- in a state in which a marine vessel moves forward in a low-speed navigating mode and when the rotation angle of the handle exceeds a first threshold, the controller is programmed to reduce an amount by which the reverse bucket covers the jetting port.
A marine vessel maneuvering system comprising:
- a jet propulsion device to jet a water current out from a jetting port and obtain a propulsive force from a recoil of the jetted water current;
- a handle to change a direction of the jetting port;
- a controller programmed to change the direction of the jetting port in accordance with a rotation angle of the handle;
- and
- a power source corresponding to the jet propulsion device to generate the water current;
- wherein
- the propulsive force increases when a rotation number of a crankshaft of the power source increases;
- and
- when a marine vessel moves forward and the rotation angle of the handle exceeds a predetermined threshold, the controller is programmed to increase the rotation number of the crankshaft of the power source.
