Knowledge & application of the IALA Buoyage System
Describe the purpose of the IALA Buoyage System
The IALA Maritime Buoyage System, often referred to as the MBS, is a guide to Marine Aids to Navigation (AtoN).
The purpose is to help all mariners navigating anywhere in the world to fix their position and avoid dangers without
fear of ambiguity. It is also to help competent maritime authorities to harmonize AtoN markings.

What are the purpose of Lateral Marks?
Lateral marks indicate the port and starboard hand sides of the route to be followed.
