Claim 2:
3. The watercraft according to claim 1, further comprising:
an acceleration operator movable in a range from a minimum output position to a maximum output position and to be operated when an output of the engine is to be changed; and
an acceleration operator position sensor to detect a position of the acceleration operator; wherein
the controller is configured or programmed to determine, based on a detection value of the acceleration operator position sensor, whether or not the acceleration operator is held within a constant speed traveling range between the maximum output position and the minimum output position, and determine, based on the detection value of the engine speed sensor, whether or not the water surface is smooth when it is determined that the acceleration operator is held within the constant speed traveling range.
