Watercraft information collecting system

A watercraft information collecting system comprising:

• an onboard system including a plurality of watercraft devices on a watercraft, an onboard network on the watercraft and connected to the plurality of watercraft devices, and a communication terminal communicable with the plurality of watercraft devices via the onboard network;
• and
• a server outside the watercraft and communicable with the communication terminal;
• wherein
• the communication terminal is configured or programmed to perform an information collection process to collect information about the plurality of watercraft devices, a use termination detection process to detect a termination of use of the onboard system, and an information transmission process to transmit the information collected by the information collection process to the server;
• and
• the server is configured or programmed to register the information transmitted from the communication terminal in a storage.

A communication terminal to be mounted on a watercraft and communicable with a server, the communication terminal comprising:

• a communication interface to be connected to an onboard network on the watercraft;
• a wireless communicator to communicate with the server;
• and
• a processor configured or programmed to function as:
• an information collector to collect information about watercraft devices on the watercraft and connected to the onboard network via the communication interface;
• a use termination detector to detect a termination of use of an onboard system;
• and
• an information transmitter to cause the wireless communicator to transmit the information collected by the information collector to the server.
