We're now doing a regatta where they spilt me from the J's, but put me at the same rating as 32&36 footers. The J's are sailed badly so don't have a chance - but nor do I against boats that have waterline lengths 10 feet longer than mine. In reality it's probably the other boats that are wrong if I consider a J IRC is 0.888 in class legal trim and Chuckles was 0.844 - that feels sort of right...
Anyway - I'll do some more digging & get back to the club or there's going to be one less boat on the line - enthusiasm is depleted ...
Many thanks
