Above board means on or above the deck, in plain view, and not hiding
anything below deck. Sea faring pirates would keep their crews below thereby
creating a false impression that an encounter with their ship was a casual
matter of chance and uh, friendly. A lot of people have a lot of ‘baggage’
below their deck so be careful who you let board your ship. Let the Dao keep
you sailing smooth with fair winds and following seas.
