All mariners need a comprehensive knowledge of the buoyage rules and should be able instantly to identify a mark at first sight. These Flip Cards show 32 different buoys and navigational marks in colour, with the meaning and position, together with the light characteristics on the back of the card. Both the Cardinal and IALA marks are featured, as well as the more recent preferred channel buoys.
This set shows buoys used in North America, Japan, Philippines and some other areas.
33 cards in the pack including the instruction card.
