But I just did a Google lookup and found quite a few references ... she was built in 1863 at the Isle of Mann, was restored in the 1970s and is now berthed in San Diego harbor, where she is billed as the "world's oldest active iron-hull sailing ship"
one site calls her a "square rigger"
another said she was originally a "full-rigged" (royals and double topsails) ship, and later re-rigged as a barque

more detailed history
about the ship's ghosts, interior pics
more story and pictures
fun story about the ship's building and launch describes her as very slow but comfortable for passengers ... they also say that the 140 year old ship is "still capable of coping with sea conditions that would send today's modern SeaCats and SuperSeaCats scurrying for shelter."
