Cardinal Marks are used for permanent wreck marking whereby North, East, South and West Cardinal buoys are placed around the wreck.

Cardinal marks are named after the four quadrants of compass i.e. North, South, East, and West. These are buoys placed mid sea and indicate that safe water lies to the named side of the mark.

A navigator will be safe if the vessel passes north of a north mark, south of a south mark, east of an east mark and west of a west mark.

This app has been developed as a quick reference guide. The mobile can be placed horizontally or held vertically for the heading to follow up.
