I'm not sure the A class is the king as much as people say any more, certainly from the handicap racing I did last year I would say that the A , F16 and F18 are all pretty equal. The F boats certainly have had a lot of sail and rig development these last few years whilst that gain was some years ago with the A's. One only has to look at the way the F18's handicap is dropping to see that this is backed up with results ( even Macca was whinging about this recently in one of his posts ).
