Yes...exactly those F18's mentioned vary quiet a bit & these days It seems the rig development is the only thing separating the later designs.

Going off topic, but it would be really interesting to see a F18 worlds with the current top 80 teams on identical F18s (Hobie 16 worlds style). Sure there would be the usual guys at the front, but there would be some interesting reults right thru the order..... <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
