Taipan does great as a uni-rig in our fleet. 2 up would be a bit dicey due to lack of volume. I wanted one for a year or so myself, thinking the same thing they are the cheap F16, but the reality is they don't exist.

Frankly I would dump both the N20's (don't get me wrong, great boat but dead class), get a F18 for two up work (350lb crew is perfect weight for an older Infusion), and find a Boyer Mk. IV A-Cat to sail solo. That would be the cheapest option, since a good used F16 is still $9K+.

I'm very curious to sail my F18 against the F16's at similar crew weights this summer, and jump on a F16 (Viper or Falcon) at our F18 crew weight (330-350lb) and see how she handles it, mostly because I like the ease of handling the F16 on the beach.
