Of course this is true. But the chat was detailing the fact that Taipans had fallen behind other boats that went to F16. My point was that IF the Taipan was a competitive boat in F16 form then have the best of both Worlds. Keep the 4.9 class but have the possiblity of factory upgrades to F16 by not going to a whole new platform for F16. The two things are not mutually exclusive. Then everyone gets the choice.
FYI AHPC does offer an F16 kit for the Taipan 4.9. With my boat, I could sail in either F16 or 4.9 OD, but it's not really relevant in the US since 4.9s are few in number.
