Officer associated with a boxer, maybe (3,7)
I believe the answer is:
sea captain
'officer' is the definition.
(sea captain is a kind of officer)
'a boxer maybe' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
'maybe' could be 'i' (I've seen this in other clues) and 'i' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'associated with' is the link.
Can you help me to learn more?
(Another definition for sea captain that I've seen is " Cook was one".)
