The Dagger Rival, though short, might

satisfy you. It is fairly round with low wetted area. There are good used Rivals available in Dagger Royalex, or you can get Kaz of Millbrook to make one in S-glass and Kevlar. However, the Millbrook version will need at least occasional repairs, though not as drastic as what you're facing. I think designer Bob Foote is paddling a Dagger Rival in the "Drill Time" video.
You can watch for a Synergy, though mine is now almost 15 years old and possibly becoming a bit brittle. Still, the Royalex on mine has seemed outstanding.
The new Wenonah ww canoe, a relatively conservative design, might be tolerably fast.
Also, the Mohawk Shaman is from a Harold Deal design which raced in the combined class, where it had to be good at both slalom and whitewater.
