Hey Stephen, those yardsticks are a little "misleading". although the Taipans have been racing for many years and their yardstick represent THEIR current comparative performance against boats such as A class, Formula 18's Tornado's and 5.8 Nacra's, there are a lot of cats on that list who's ratings have been "stuck in time" and bear no relationship to current performance (if in fact all of them were even still racing)
One comparison that you have neglected is the comparison of the CURRENT Yachting Victoria yardstick rating for the F14, which at 77 compares very favourably to the 76.5 and the 73.5 for the Taipan. (If I were sailing a Taipan I would definitely want it set up as an F16, if for no other reason than to “get the F14’s off my back”)
