As everyone has said, mooring is the name of the
game in most places on the BVI. Checkout BoatyBall.com since some of the more popular harbors use this to reserve balls (e.g.
Cooper and Great Harbor JVD). There are a few first-come-first-served balls but it might be less stressful to reserve.
Workout your bow crew hand signals for mooring and review how to use the lines to attach to a ball.
You will also need to use the dinghy but MM will show how. When we first chartered a cat, Moorings sent us out with a free
skipper to evaluate our competence. He was really good. We went to Peter Island and practiced mooring and
anchoring. He helped us to get team
work going. All in all a great experience that did not take that much time.
I would not suggest to try
Cooper Island on your first night. It's a great place and we always go there but it is crowded and sometimes (always?) the boat dances around at night and can hit the mooring ball. It's not been an issue for us, but might be alarming on the first night.
I would suggest Norman Island on the first night. It's a big harbor with lots of balls. There is a decent beach bar, you can snorkel right off the beach and see interesting things, the caves are well worth a snorkel for the number of
fish, and there is the Willy T. It should offer a calm nights sleep to help everyone acclimatize to sleeping on a boat. Norman does not use BoatyBall.
