I know Russ has been at it a long time having brought his J/30 halfway across the country. Like most of us he supports his club, the class and has made efforts to organize a fleet. I just don't think a 'throw down' is consistent with the compromises needed to encourage one-design racing.
Yes I do think a Kevlar/carbon mainsail is faster. Officially PHRF doesn't 'rate' sailcloth. But effectively they do through one-design ratings (ODR). Boats that do not comply with class rules usually do things to make their boats go faster. There are six ODR Hobie 33's racing in or near North Cape YC. I know you are going to tell me they all use Kevlar, but is there anything they doing differently that has made their fleet more successful?
