SYSTEM FOR AND METHOD OF CONTROLLING WATERCRAFT

A system for controlling a watercraft includes a data communication module, a device system, an electric power supply, and a controller. The data communication module is operable to perform wireless communication with an external computer. The device system includes at least one electric device. The electric power supply provides electric power to the data communication module and the device system. The controller is configured or programmed to switch between a first mode and a second mode. In the first mode, the controller provides electric power to the data communication module by the electric power supply during both activation and deactivation of the device system. In the second mode, the controller provides electric power to the data communication module by the electric power supply during the activation of the device system, but stops providing electric power to the data communication module by the electric power supply during the deactivation of the device system.
