Wow, you got a first mate. How many were in your group/ on your boat!
There were 12. Two (Blue Angle) DMs and a Captain and First Mate. This was not a B.A.D.A.S.S. boat, it was hired (?) to handle our group due to transmission issues (?) with their big boat.
I have, not always, but often enough had a captain and deck hand or mate plus DM, so I cannot agree with some who say never.
