Can one person rig the boat? Yes if you set up a rig to raise the mast.

Can one person sail boat with jib furled- or unfurled? Yes. Depending on wind speed one person can sail with the jib in either configuration. The nice thing about furling jibs is the ability to reduce power quickly.

Can one person right the boat? Probably. It'll take either a water bag setup or a power pole righting system.

How does it pitchpole compared to a 16? 16s are more succeptable to pitch poling. The 18 has more flotation forward and a higher bow which reduces the chance of pitch poling. That doesn't mean they won't. I've seen some pretty spectular 18 crashes.
