A navigational information displaying device sequentially acquires first geographic coordinates of a first ship traveling on the sea, and generates a first object indicative of the first ship at first indication coordinates in an image displayed on a display unit. The device generates a first window indicating the first object and moving in the image in association with movement of the first object or an indication viewpoint, accepts a specification of second indication coordinates in the image from a user, and generates a second window indicating the second indication coordinates. The device acquires second geographic coordinates corresponding to the second indication coordinates, and calculates navigational information including a distance between the first and second geographic coordinates. The device displays the first object, the first window, the second window, and the navigational information in the image, and controls the first and second windows to not overlap with each other.
