Lateral marks

Lateral Marks are used generally to mark the sides of well-defined, navigable channels. They are positioned in accordance with a Conventional Direction of Buoyage

Lateral marks indicate the port and starboard hand sides of the route to be followed. They are coloured red (port hand marks) and green (starboard hand marks).

General Direction of Buoyage

Around the British Isles the General Direction of Buoyage runs north along the west coast and through the Irish Sea, east through the English Channel and north through the North Sea (the opposite is true in IALA system B, for example in the USA).
