Drying contour

Low Walet (LW) Linę, Chart Datum (CD)

Blue tint, in one o r morę shades, and tint ribbons, are shown to different limits according to the scalę and purpose of the chart and the naturę of the bathymetry.

On some charts, the standard set of contours is augmented by additional contours in order to delimit particular bathymetric features or for the benefit of particular categories ofshipping. However, in some instances where the provision of additional contours would be helpful, the survey data available does not permit it.

On charts showing depths in fathoms/feet, the following contours are used:
