A water area object detection system includes a first imager to image an object around a hull, a second imager provided on the hull such that an imaging direction of the second imager is the same or substantially the same as an imaging direction of the first imager and operable to image the object around the hull, and a controller configured or programmed to perform a control to create a water area map around the hull based on images captured by the first imager and the second imager. The second imager is spaced apart in an upward-downward direction of the hull from the first imager, and the first imager is spaced apart in the imaging direction from the second imager so as not to overlap the second imager in the upward-downward direction perpendicular to the imaging direction.

A water area object detection system includes an imager to capture an image around a hull, and a controller configured or programmed to perform a control to detect a feature point corresponding to an object in the image together with a distance to the feature point based on the image captured by the imager to create a water area map in which an object presence range including a likelihood that the object is present is set around the feature point. The controller is configured or programmed to reduce the object presence range as the distance from the imager to the feature point decreases, and set a size of the object presence range to a lower limit when the distance from the imager to the feature point is equal to or less than a predetermined distance.

Systems, assemblies, and methods for conveniently operating marine devices associated with a watercraft are provided herein. An example system includes a controller, a sensor module, and a marine device. The controller is configured to receive a user input indicating a desired action via the sensor module and transmit a signal to the marine device to cause the marine device to operate in a particular manner. The sensor module may include one or more motion sensors, and the controller may be configured to filter unintentional movement from the raw motion data sensed by the sensor module, such as due to movement of the watercraft floating on the surface of the water. Thus, the system may enable convenient and intuitive control over various marine devices associated with the watercraft.

[Problem] To provide a collision damage reduction system for watercrafts, which system is usable even when a user watercraft stops or is moving at slow speed.

[Solution] A collision damage reduction system for watercrafts comprises: an information acquiring device for acquiring information on a user watercraft 2 and a target watercraft 11; a turning device for turning the user watercraft 2 to change a front-rear direction thereof; and a control device configured to acquire the information from the information acquiring device, and control the turning device based on the acquired information. When detecting a risk of collision between the user watercraft 2 and the target watercraft 11, the control device controls the turning device such that the turning device turns the user watercraft 2 to a state in which the front-rear direction thereof is parallel to a moving direction of the target watercraft 11.
