Away from the bow (3)
I believe the answer is:
aft
'away from the bow' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aft that I've seen before include "behind at sea" , "Towards the back on board" , "Towards rear (of ship)" , "To the rear on board" , "Farther back on board" .)
