Yes, the Nacra/Inter 20. You probably cannot see the angle from looking at the sterns, but a direct view of the bows makes it almost apparent. I got the "Four Degrees" quote from Tom Leobold when I crewed for him recently.

I'm almost anal when it comes to spelling/grammar- I read a lot of books so that helps me some. Then I come online to sailing, jeeping, and photography forums and everything goes to hell. Any errors from foreigners I can completely understand, but I come across a lot of native-English speaking adults who can't spell and have no clue how to properly use a comma
