Abstract
A watercraft positional information managing system in which GPS-based positional information is prevented from being falsified includes a server and a watercraft. The watercraft includes a propulsion device and a communicator to communicate with the server. The communicator includes a position detector to detect positional information of the watercraft. The propulsion device includes an engine and a controller configured or programmed to control the engine. The controller is connected to the communicator and outputs data related to the engine to the communicator. The communicator transmits the data related to the engine and the positional information of the watercraft to the server. The server receives the data related to the engine and the positional information of the watercraft and determines whether or not the positional information of the watercraft is genuine based on the data related to the engine.
