Well, I'll start:
1. Nanny Cay - Best marina showers in the BVI, possibly best in the Caribbean. Don't leave the dock without taking advantage of them.
2. Sail the boat kind of flat. Newbies are probably not comfortable with much heeling. It is usually a bit breezy down there.
3. Give the newbies instruction and responsibilities. Let them drive, too. They will appreciate it.
4. Depending on the season, don't wait all day to get to your mooring for the night. They can fill up by mid afternoon.
5. Check with Nick at Leverick Bay for TTOL special and make a reservation for a slip if you haven't already don so...and tell him Hi for me.
6. Go to Anegada and don't miss Cow Wreck Beach.
