Actually there are still a considerable number of 5.2s around. I know of several in FL and there's a significant local fleet in the midwest somewhere. It was a very well respected boat in it's time. At Spring Fever, there were four preregistered (although none of them except me showed up due to the bad short term weather forcast).

Regarding the rigging, except for a few nuances, all catamarans are rigged in a similar fashion. Keep the questions coming - we'll keep answering!
