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 31 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 the 'A' Region buoys which are found in most areas of the world but NOT in North America, Japan, Philippines and some other areas which use IALA System B just to confuse things.
