I also know all three boats and would in a heartbeat go for a nice Nacra 5.2 in a heartbeat.That is, if you don't want to racein a Hobie fleet.

Great to single-hand and less chance to pitchpole that a H16 (I think this is my hang-up of which I'm deadly afraid, having gotten "killed" a few times in pitchpoling H16s and H18s).

Maintenance is also less on a Nacra 16, especially the simple rudder system. I think it's just more stable--also less chance of breakage. Older H16s have broken at the stanchions (or is it spelled "stantions"?).
