Frigate's front (3)
I believe the answer is:
bow
'frigate's front' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bow that I've seen before include "Stoop" , "Bend in reverence or submission" , "Arc" , "Bend from the waist in deference" , "Front part of a ship" .)
