I just signed up at a yahoo groups for information unrelated to sailing. In doing so I made a new user that caused me to start from scratch. It’s changed since I made my sailing user. A whole gauntlet of junk mail now needs to be unchecked to avoid automatic sign-up. No worse I guess than most web places these days. MSN is still in my book the most annoying. The price of “free” I guess.The list that Dan refers to has several boats with sails showing 'SS'. Therefore, just go there and take a look.
PS: You will have to 'join' the Yahoo group, but there are no nasty ramifications if you do.
In case this approach keeps you guessing, you may have to consider the possibility that the sail and hull don't match
