Abstract
A system for a marine vessel propelled by a propulsion device includes a controller operable in an automatic navigation mode in which the controller automatically controls a thrust of the propulsion device to propel the marine vessel through a body of water. A portable device is carried on an individual on the marine vessel. The controller enables a person overboard detection algorithm in response to enablement of the automatic navigation mode. The person overboard detection algorithm disables the automatic navigation mode in response to detecting a given status of the portable device.
Claims20
A system for a marine vessel propelled by a propulsion device, the system comprising:
- a controller operable in an automatic navigation mode in which the controller automatically controls a thrust of the propulsion device to propel the marine vessel through a body of water;
- and
- a portable device configured to be carried on an individual on the marine vessel;
- wherein the controller enables a person overboard detection algorithm in response to enablement of the automatic navigation mode;
- and
- wherein the person overboard detection algorithm disables the automatic navigation mode in response to detecting a given status of the portable device.
A method for controlling a propulsion device on a marine vessel, the method comprising:
- enabling an automatic navigation mode in which a thrust of the propulsion device is controlled automatically to propel the marine vessel through a body of water;
- enabling a person overboard detection algorithm in response to enablement of the automatic navigation mode;
- and
- disabling the automatic navigation mode in response to the person overboard detection algorithm determining that an individual on the marine vessel may have fallen overboard.
