Drinks provided for men on board (8)
I believe the answer is:
draughts
I believe this is a double definition.
'drinks' is the first definition.
(I know this)
'for men on board' is the second definition.
(I've seen this before)
'provided' acts as a link.
(Other definitions for draughts that I've seen before include "Lots of fish caught" , "medical doses" , "Checkerboard game for two players" , "Board game for two" , "Half of 1D [GAME OR BIRD]" .)
