Royal Caribbean Cruise Line changed their name a few years ago to Royal Caribbean International. They since have come out with new racks of chips that for the most part say Royal Caribbean International and have the trademark symbol. In still other cases they have come out with completely new chips on many of the ships. It is near impossible to catch up with all the changes. I am sure there are textured and smooth variations with several chips too. I can't be bothered with those type of variations. I am currently working on a web site that should be an update to our book. There will about 300-400 more chips that were not in our book. I continue to number new chips as they come out even if I don't have them yet. If you need to know what number has been assigned to any new wet chips let me know. In some cases I may not know of the chip but I can still assign a number to it for you.
