International Regulations for Preventing Collisions at Sea also known as COLREGS – These cards show the view forward from the deck of various vessels (power, sailing and fishing) of developing traffic situations at sea. In each case the mariner has to decide the correct course of action to navigate their vessel through the hazard. The reverse of the card gives the proper course and also quotes the relevant collision rule.
There are 50 cards in the pack including the instruction card.
