Abstract: A positional sensor detects a current position and a current bearing of a boat body and outputs position information indicating the current position and the current bearing. A controller receives the position information. The controller determines a first target position of the boat body and a target bearing in the first target position. The controller calculates a bearing difference between the current bearing and the target bearing. The controller determines an offset amount of the first target position in response to the bearing difference or an outside disturbance. The controller determines a position spaced away by the offset amount from the first target position on a side toward the current position as a second target position. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the second target position.

Abstract: A first sensor detects first environment information indicating a shape of a shore arrival location and a positional relationship between the shore arrival location and a boat body. A second sensor, different from the first sensor, detects second environment information indicating the shape of the shore arrival location and the positional relationship between the shore arrival location and the boat body. A controller is communicatively connected to the first sensor and the second sensor. When the distance from the boat body to the shore arrival location is greater than a predetermined distance threshold, the controller generates, based on the first environment information, an instruction signal to control a propulsion device to as to cause the boat body to arrive at the shore arrival location. When the distance from the boat body to the shore arrival location is equal to or less than the distance threshold, the controller generates an instruction signal based on the second environment information.

Abstract: A sensor that detects a shape of a surrounding environment of a boat and a positional relationship between the surrounding environment and the boat body outputs environment information indicating the shape of the surrounding environment and the positional relationship. A display displays an environment map indicating the surrounding environment. An input accepts an input of a shore arrival target position of the boat body on the environment map and outputs target position information indicating the shore arrival target position. A controller receives the environment information and the target position information, determines a possible shore arrival space of the boat body in the surrounding environment based on the environment information, and corrects the shore arrival target position based on the possible shore arrival space. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the shore at the corrected shore arrival target position.
