Bones makes call tracking old vessel’s location (8)

I believe the answer is:
moorings
'bones makes' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'call tracking old vessel's location' is the wordplay.
I cannot really understand how this works, but
'call' could be 'ring' (telephone call) and 'ring' is found within the answer.
'old' could be 'o' (abbreviation) and 'o' is present in the answer.
The remaining letters 'mos' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for moorings that I've seen before include "Berths" , "Anchorage" , "where cats may be secured" .)
