This has been talked before and I think that people has not come up with good reasons being a ISAF class. I would guess though that certifications tend to give people assurance that class is run "certified" way and maybe it would shut up some of our critics points even if it wouldn't change anything <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />. Also we could have World championships after that (again just a name of an event).
