Do a search on this site to see if you can find past posts. I inquired about it a year or so ago. Our group is planning on attempting the trip to St. Croix this winter. Will be curious to read responses to your post. There is a marina in St. Croix once you get there and there are some mooring balls in front of Dive Experience on the boardwalk. However, most of those are private. I would contact the marina to reserve a slip if you're planning on going over.
