Thanks, the logo looks very nice but I agree w/Mary that it should not have periods in between the letters.
I, like Fred, think also that the shirts should have some sort of visual reference to catamaran sailing.
Anyway, you must be saying this is Monday morning quaterbacking and you are right ! it is very difficult to come out with a logo and it takes a lot of creativity to do it so I thank you for it.
