Jet propulsion watercraft, jet propulsion watercraft control system, and method for maintaining jet propulsion watercraft in docked state

A jet propulsion watercraft control system comprising:

• a jet propulsion watercraft;
• and
• a remote control to remotely control the jet propulsion watercraft;
• wherein
• the jet propulsion watercraft includes:
• a hull;
• a water flow generator to generate a jet of water to provide a propulsive force to the hull;
• a water flow direction adjuster to adjust a direction of the jet of water from the water flow generator;
• and
• a controller configured or programmed to, when a docked state maintenance operation is performed to maintain the hull in a state docked at a pier, perform a docked state maintenance control to control the water flow generator to maintain generation of the jet of water from the water flow generator while controlling the water flow direction adjuster to maintain the direction of the jet of water from the water flow generator in a direction to cause the hull to be pressed against the pier.
