I didn't write the TCC rules. I'm just trying to keep it alive. I wonder why at times especially with your fine helpful responses. Harpoonette and I have discussed just letting it die a good death. It's been around for probably close to 20 years now. The TCC has had it's up's and downs for sure.
I don't know the origins/reasoning behind the sail one boat, score one boat rule. but I am thinking that it is because some people have/had a good wardrobe of boats. So at this light air venue I'll sail my Thistle, Johnson 18, AC or MC scow and when I go to Seabrook and it is rough as a cob and heavy air I'll get out the Contender or whatever boat I have that handles chop better.
I've also been informed that there used to be a 24 hour rule is which all excuses as to why you didn't do well had to be registered when they had the Yahoo TCC group up and running.
