Abstract
A boat includes a steering load detector arranged to calculate an output value of a steering motor necessary for steering an outboard motor in a traveling state, a motor output detector arranged to detect a possible output value that can be output by the steering motor, a prediction determination unit arranged to compare the necessary output value from the steering load detector with the possible output value from the motor output detector, and an electric power load control unit arranged to perform a control operation so as to increase a battery charge amount and/or to reduce the electric power load when the necessary output value is determined to be larger than the possible output value. As a result, the boat that can effectively perform steering when a motor output becomes small as a result of a reduced battery charge amount.
Claims5
A boat comprising:
- a boat propulsion unit mounted on a hull in a rotatable manner;
- a boat propulsion unit operation controller disposed in the hull to be steered by an operator;
- a steering motor to steer the boat propulsion unit based on steering control of the boat propulsion unit operation controller;
- a signal cable to electrically connect the steering motor and the boat propulsion unit operation controller;
- a steering load detector to calculate a necessary output value of the steering motor required to steer the boat propulsion unit in a traveling state;
- a motor output detector to detect a possible output value that can be output by the steering motor;
- a prediction determination unit to compare the necessary output value from the steering load detector with the possible output value from the motor output detector;
- and
- an electric power load controller to control a battery charge amount to be increased and/or to control an electric power load to be reduced when the necessary output value is determined to be larger than the possible output value by the prediction determination unit.
