摘要： A small watercraft system includes: a watercraft body; a watercraft body manipulation member through which a watercraft body manipulation command is input by an operator; a drive source that allows the watercraft body to plane; a steering device that allows the watercraft body to be steered; and a control device that controls the drive source and the steering device to operate the watercraft body. The control device determines whether a mode switching condition is satisfied, the mode switching condition including an operator's absence condition that the operator is absent from the watercraft body. Upon determining that the mode switching condition is satisfied, the control device executes an operator-absent manipulation mode in which the control device moves the watercraft body by controlling the drive source and the steering device based on an operator-absent manipulation command independent of the watercraft body manipulation command.
