I don't read all these rating threads, because I don't understand them. But I do have questions:

How many ratings systems are currently in use by beach cats, and where is each used? For instance, is the Texel system used throughout Europe? Is the Portsmouth system used anywhere besides North America? What is used in Australia? South Africa? The Orient? The Caribbean?

Also, is there currently enough interaction (racingwise) among these various parts of the world to make it necessary or advisable to have the same rating system for cats worldwide?

Would it be easier to compare relative boat performance, as reported from different regions and continents, if we knew they were all using the same rating system?
