A water area object detection system includes an imager (1a) configured to capture an image around a hull (101), and a controller configured or programmed to perform a control to detect a feature point (F) corresponding to an object (O) 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 (M) in which an object presence range (F1) 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 (1a) to the feature point (F) decreases, and set a size of the object presence range to a lower limit (r1) when the distance from the imager to the feature point is equal to or less than a predetermined distance (d1).
