IMHO...

1) Use the friendly skipper
2) Have Moorings dock the boat at the end and possibly take it out
3) Dont skimp on the boat briefing and have others watching
4) Have a second in command..."I watch the boat and you watch the crew"
5) Have your own boat briefing...I go over my rules of the boat

Depending on when you go Moorings should be able to "round up" a skipper last minute. I take a boat out a Moorings 514PC bareboat 3-4x per year but always try to be mindful that for me it is still an "away game" and not my equipment. People get hurt or worse down there all time as you can read about on this board. I came close to losing someone in Feb '19.

I dont mean to scare you but if you have concerns talk to your captain and suggest he hop on this board for a while. The people on here are some of the most knowledgeable and helpful you will ever meet. At then end of the day having boated decades and being a licensed Captain down in the BVIs I am still a "credit card captain".
