alan we race on lake erie phrf and have wind most of the time in the 0-5 or 15-25 we never get off easy the waves are steep and close. we never use the vang up wind(if you are trying to twist the vang will pull the top batten in and stall the sail)number one is used to 15 true and the number 2 is the smallest we will use,the 2(#3 IF LIGHT CREW AND/OR 25+TRUE) is the most underused sail in the J30 FLEET or so it seemes from the postings.
