Buoy Identification chart

The need for dependable aids to navigation can be traced to the beginnings of maritime commerce. Today, mariners in unfamiliar waters still welcome the sight of lighthouses, buoys, beacons, and other navigational aids as guideposts to safe harbor.

The IALA Bouyage System is a worldwide standard sea mark system used in navigation to mark the edge channels. These road signs on the water are made up of five buoy types- cardinal, lateral,isolated danger, special and safe water marks. These buoys and marks indicate where safe water lies and where you should navigate safely within a channel.
