Ship's company sounded cocky? (4)
I believe the answer is:
crew
I believe this is a double definition.
'ship's company' is the first definition.
(I've seen this in another clue)
'sounded cocky?' is the second definition.
(ie made a cock's crow)
(Other definitions for crew that I've seen before include "group of sportsmen" , "was triumphant" , "emulated cocks" , "Sailor complement of ship" , "Was exultant" .)
