Several zone members have done this, but the person with the most experience, I believe, is Joe Ayala (songman55). The only ships I performed on were smaller ones that returned to port the same day. It was a fun job, but the pay was lousy and getting your gear on/off the ship was a real struggle. Hopefully, Joe will enlighten you on this.
