1. A maritime route display device configured for use on a ship, comprising:
a display device; a Global Positioning System (GPS) sensor; a non-volatile memory device; and a processor configured to:
acquire a position and a direction of the ship at least from the GPS sensor;store positional information of a beacon or a channel buoy on the non-volatile memory device;store a route defined by a plurality of operator-specified waypoints on the non-volatile memory device;display a straight line representation of the entire route that includes the plurality of operator-specified waypoints located at intervals along the straight line in proportion to actual relative distances between the waypoints in a vertical axis of the display device;determine positional relations of the ship and the one or more targets with respect to the route in left-and-right directions of the route, the one or more targets including the beacon or the channel buoy;display the ship and one or more targets in a horizontal axis of the display device with respect to the straight line representation of the entire route according to the determined positional relations of the ship and one or more targets with respect to the route; andcontrol a display position of the ship and the one or more targets with respect to the straight line representation of the entire route.
