Trailering support device and method, and marine vessel including trailering support device

A trailering system comprising:

• a marine vessel including a hull;
• and
• a trailering support device to load the hull onto a trailer, the trailering support device including:
• one or more controllers configured or programmed to function as:
• a first acquisition unit to acquire characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull;
• a second acquisition unit to acquire relative position information between the trailer and the hull;
• a detector to detect the steering angle of the hull;
• a generation unit to predict future movement of the hull based on the characteristic information acquired by the first acquisition unit, the relative position information acquired by the second acquisition unit, and the steering angle detected by the detector, and to generate a predicted trajectory;
• and
• a control unit to provide notification of a positional relationship between the hull and the trailer and provide notification of the predicted trajectory generated by the generation unit.

A trailering support method for loading a hull onto a trailer, the trailering support method executable by a computer and comprising:

• acquiring characteristic information indicating a relationship between a steering angle of the hull and a turning radius of the hull;
• acquiring relative position information between the trailer and the hull;
• detecting the steering angle of the hull;
• predicting future movement of the hull based on the acquired characteristic information, the acquired relative position information, and the detected steering angle, and generating a predicted trajectory;
• and
• providing notification of a positional relationship between the hull and the trailer, and providing notification of the generated predicted trajectory.
