The powers that be have determined I'm not allowed to go sailing unless I take my daughter with me, and she's still too young, so I might as well fill the next couple of years worth of sailing time with building a boat instead.

F16, F14... whatever, they are both more senior classes than the F12 and the proposed-and-now-dead concept F14-sloop / 430 would be, they can be on the horizon for 10 years time.
