Dangers in the open SEA - My favorites quotes from the famous Bowditch

"There are two major types of buoyage systems: the lateral system and the cardinal system. The lateral system is best suited for well-defined channels. The description of each buoy indicates the direction of danger relative to the course which is normally followed. In principle, the positions of marks in the lateral system are determined by the general direction taken by the
mariner when approaching port from seaward. These positions may also be determined with reference to the main stream of flood current.

The cardinal system is best suited for coasts with numerous isolated rocks, shoals, and islands, and for dangers in the open SEA. The characteristic of each buoy indicates the approximate true bearing of the danger it marks. Thus, an eastern quadrant buoy marks a danger which lies to the west of the buoy."
