I've seen listings for "Hobie 16 Jib Sheet Setup Sailboat Prindle Nacra". I'm not sure what Prindle Nacra refers to. It sounds like another type of catamaran.
As the previous poster stated, Prindle and Nacra are other brands of catamaran. Often when people are selling parts for these other boats on craigslist or ebay, they'll stick the word Hobie in the ad too. Because Hobie is a much larger company, most people searching for beach cats or beach cat parts will just put "Hobie" in the search engine (many people consider Hobie to be a generic term for beach cat).
In any case, jib parts from a Prindle or Nacra will most likely NOT work on your H16. For that matter, jib parts from other size Hobies will likely not work on your H16 either. The H16 jib system is unique.
