When increasing the ENC scale, presentation of Own Ship will change from a double circle with an arrow to a defined symbol or shape. The S-52 Standard stipulates that the mariner should be allowed to select whether Own Ship is displayed in true scale or as a symbol or shape, and that the selection may be made manually or automatically.
Own Ship presented in true scale on the largest scale display gives the possibility of high navigational accuracy when transiting small rivers and river bends; also for narrow channels e.g. docks, locks or bridges.
