Abstract
A marine vessel having a propeller that provides propulsive force to the marine vessel, and a course control system. The course control system includes a course changing mechanism that changes a course of the marine vessel, and a controller configured or programmed to detect a sudden movement of the marine vessel originating from broaching caused by a following wave of the marine vessel, and upon detecting the sudden movement of the marine vessel originating from the broaching, control a rotation rate of the propeller and/or cause the course changing mechanism to change the course of the marine vessel.
Claims20
A course control system for a marine vessel having a propeller that provides propulsive force to the marine vessel, the course control system comprising:
- a course changing mechanism that changes a course of the marine vessel;
- and
- a controller configured or programmed to:
- detect a sudden movement of the marine vessel originating from broaching caused by a following wave of the marine vessel, and
- upon detecting the sudden movement of the marine vessel originating from the broaching, control a rotation rate of the propeller and/or cause the course changing mechanism to change the course of the marine vessel.
A marine vessel comprising:
- a propeller that provides propulsive force to the marine vessel;
- and
- a course control system including:
- a course changing mechanism that changes a course of the marine vessel;
- and
- a controller configured or programmed to:
- detect a sudden movement of the marine vessel originating from broaching caused by a following wave of the marine vessel, and
- upon detecting the sudden movement of the marine vessel originating from the broaching, control a rotation rate of the propeller and/or cause the course changing mechanism to change the course of the marine vessel.
A course control system for a marine vessel, comprising:
- a controller configured or programmed to:
- detect whether or not broaching has occurred or preconditions of occurrence of the broaching are satisfied based on a length between perpendiculars of a hull of the marine vessel, and a wavelength, a wave height, and a traveling direction of a following wave.
