The right question should be "Why are navigation aids reversed in US?" The navigation lights and marks are prescribed across the world by the International Association of Lighthouse Authorities (IALA). In 1977 IALA endorsed two maritime buoyage systems putting an end to the 30 odd systems existing at that time. Region A - IALA A covers all of Europe and most of the rest of the world, whereas region B - IALA B covers only the Americas, Japan, the Philippines and Korea. Fortunately, the differences between these two systems are few. The most striking difference is the direction of buoyage. The reason for IALA B is that some Western and Asian countries did not accept the recommended uniform system IALA A.
If country A attacks country B, then A's allies also attack country B, and B's allies all come to the defense of B.
Region A-apex
Region B
This depends what kinda of cans you are talking about? Are you referring to IALA-B, International Association of Lighthouse Authorities Region B Buoyage system (United States) ?Can buoys for navigation in this region are almost always green & numbered odd. There maybe yellow cans or white, which are special purpose buoys. These either mark a danger area, no wake or special instructions. Yellow buoys may have a unique special purpose.The opposite of green cans is red nun buoys, which are even numbered. Also you may find Cans or nuns marked with both red and green bands which makes them preferred channel markers.

Making the blank tile to the letter "G" would give you the word: Buoyage: a group of buoys.
