Flip Cards - Rule of the Road

International Regulations for Preventing Collisions at Sea

also known as ‘Col Regs’ - 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 his/her vessel through the hazard. The reverse of the card gives the proper course and also quotes the relevant collision rule.
