Abstract: A watercraft includes a hull, an engine to generate power to propel the hull, an engine speed sensor to detect the rotation speed of the engine, and an ON/OFF sensor to be turned on and off according to a vertical acceleration of the hull. The watercraft further includes a controller configured or programmed to determine, based on at least one of a detection value of the ON/OFF sensor and a detection value of the engine speed sensor, whether or not a water surface is smooth.

Abstract: A small marine vessel includes a hull and an outboard motor attached to the hull to be rotatable about a first axis extending along a front-rear direction of the hull and to be movable in an up-down direction of the hull so as to more actively contribute to the maneuverability of the small marine vessel.

Abstract: A marine vessel to improve a transmission characteristic of a rescue signal when the marine vessel is capsized includes a transmission source to transmit a rescue signal to a vicinity above a water surface both when the marine vessel is not capsized and when the marine vessel is capsized.

Abstract: A marine vessel to transmit a rescue signal includes a hull, a propulsion force generator to generate a propulsion force to propel the hull, and a controller. In the marine vessel, the controller is configured or programmed to acquire vessel speed information regarding a vessel speed of the hull, and determine whether or not rescue is necessary based on the vessel speed information in a case where operation of the propulsion force generator is stopped.

Abstract: An information processing method includes displaying a water-based map on a display unit, accepting an operation by an administrator, storing a selected tile by the administrator in a storage unit as a particular tile from among a plurality of tiles resulting from division of an area on the water-based map into a mesh pattern, detecting a present location of a ship at a predetermined time interval, and notifying an alert when the ship enters a water area corresponding to the particular tile.

Abstract: A marine vessel includes a vessel body including a navigation light, an imager provided in a vicinity of or adjacent to the navigation light, and a light shield provided between the navigation light and the imager so as to block light from the navigation light to the imager.

Abstract: A marine vessel maneuvering system includes an engine and a controller configured or programmed to control a marine vessel. The controller is configured or programmed to set a control of the engine for each destination based on at least one of information indicating the destination acquired incident to a setting operation of the destination by a distributor or information indicating the destination acquired from a ground-based or sea-based base station at the destination.

Abstract: A marine vessel display device includes an imager that images surroundings of a vessel body, an image processor that generates a bird's-eye view image based on images captured by the imager, a display provided in the vessel body and that displays the bird's-eye view image, and a controller. The controller is configured or programmed to perform a control to switch an image displayed on the display from the bird's-eye view image to an object image obtained by imaging in a direction toward an object from the vessel body based on object information.

Abstract: A watercraft includes a hull, a wave detector to detect wave conditions on a water surface, a trim adjuster to adjust a trim angle of the watercraft, and a controller. The controller is configured or programmed to determine, based on a detection value of the wave detector, whether or not the water surface is smooth and, if it is determined that the water surface is not smooth, control the trim adjuster to increase the trim angle.

Abstract: An imaging device that reduces differences between a bird's eye image and an actually measured distance includes imaging cameras mounted on a ship to capture peripheral images of the ship and combines the peripheral images captured by the imaging cameras to create the bird's eye image as a composite image. The imaging device includes an auxiliary camera adjacent to at least one of the imaging cameras, and a distance calculator that calculates a distance in a lateral direction using the auxiliary camera and the at least one of the imaging cameras adjacent to the auxiliary camera.

Abstract: An imaging system for a ship includes cameras mounted on the ship and spaced apart at a predetermined interval, and a controller that combines peripheral images of the ship captured by the respective cameras to create a simulated bird's eye image. Adjacent ones of the cameras are located at positions and angles so that the peripheral images include a common portion of the ship. The controller performs a calibration process to adjust areas of the peripheral images to be used for the bird's eye image based on a calibration index located at a portion of the ship and included in the common peripheral images.

Abstract: A marine vessel includes a hull including a cabin, an imager that images a field-of-view shielded region, which is a region in which a marine vessel operator's field of view is obstructed when the marine vessel operator located on an operation seat provided inside the cabin looks around an outside of the marine vessel in a horizontal direction, and a display provided at a position visible from the operation seat and that displays a field-of-view complement image, which is an image of the field-of-view shielded region captured by the imager.
