Yeah, I hear you Rolf, and you have a point... My spin on my HT is based on the Tornado spin shape, and other classes (F16, F18) probably have seen the same influence on sails from the Tornado.

But on the other hand, my Acat sail maker and my Acat mast maker dont have any involvement in T's and the guy who designed my hulls doesnt either.

At to take that point a bit farther, nobody adopted the Marstrom carbon snuffer tubes that the T guys use. Johnstone put one on his HT and one other guy bought one but thats it. No F16's or F18's use any of the snails or Carbon tube snuffers.

So how much more sail R&D could we expect out of the T's?

The T's still used centerboards, so they didnt offer any impact on gybing boards, Tfoil rudders or other foil ideas that might translate.

Did the Velocitek, or the new single strand kevlar rigging come from the T's? Other classes has carbon masts before the T's.
