That particular Moth may not have been the best in the world, however neither was the F18 (myself) or the 18.

Straight line speed on the upwind and the VMGs on the down wind..... The F18 was quicker than the foiling Moth and 18 Skiff......Noticeably. The 18 had slightly better VMG downwind only in the realy light stuff when we were forced to go wild. That is straight line speed baring mistakes.

When Rowan (World Champ at the time) beat some A Class cats in Vic a few years ago around the cans..... Where were the Worlds best A sailors such as Gashby. Compare apples with apples. I have beaten Marstrom Tornadoes on my F18 but would be a fool to say the F18 is quicker than a Tornado.

Once again, those comments are Bladerider marketing BS and should be taken that way.
