Abstract
A boat includes a propulsion device that generates, by driving of an engine, a propulsive force to propel a boat body, a trim changer that changes a trim angle of the boat body, a trim actuator that drives the trim changer, and a controller configured or programmed to control operation of the trim actuator based on a value corresponding to a change in a boat speed.
Claims20
A boat comprising:
- an engine;
- a propulsion device to generate, by driving of the engine, a propulsive force to propel a boat body;
- a trim changer to change a trim angle of the boat body, the trim changer being changeable in incremental levels to a predetermined number of set orientations;
- a trim actuator to drive the trim changer;
- and
- a controller configured or programmed to control an operation of the trim actuator based on a value corresponding to a change in a boat speed per unit time to change the trim changer, in the incremental levels, to one of the predetermined number of set orientations.
A trim angle control method for a boat including a trim changer that changes a trim angle of a boat body and a trim actuator that drives the trim changer, the trim changer being changeable in incremental levels to a predetermined number of set orientations, the method comprising:
- acquiring a value corresponding to a change in a boat speed per unit time;
- and
- changing, in the incremental levels, the trim changer to one of the predetermined number of set orientations by controlling operation of the trim actuator based on the value corresponding to the change in the boat speed per unit time.
