Aboard naval vessel, men worried by loud noise threatening mutiny (13)

'aboard naval vessel men worried by loud noise threatening mutiny' is the definition.
I can't tell whether this defines the answer.

'aboard naval vessel men worried by loud noise' is the wordplay.
I cannot quite see how this works, but
'aboard' could be 'in' (eg in a vehicle) and 'in' is found in the answer.
'vessel' could be 'sub' (submarine is a type of vessel) and 'sub' is located in the answer.
'men' could be 'or' (military abbreviation for other ranks) and 'or' is found within the answer.
'worried' could be 'ate' (something worrying may eat someone up) and 'ate' is found within the answer.
'noise' could be 'din' (din can mean a loud noise or disturbance) and 'din' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
