Wow, thanks everyone. fallard, you have shared some invaluable info. Those Island Packets at Island Yachts are beautiful boats. I'm liking the idea of chartering out of St. Thomas. Thanks again.
I looked at the Island Packets this year but I needed to travel Saturday with a Sunday morning briefing.....and they close on Sunday! So I went back to good old, cheap and cheerful, Conch Charters. May or may not be an issue for you.
