Send soprano in (4)
I believe the answer is:
'send' is the definition.
(to send overseas)
'soprano in' is the wordplay.
'soprano' becomes 's' (musical abbreviation).
'in' becomes 'hip' (both can mean fashionable).
(Other definitions for ship that I've seen before include "Large craft" , "Take on" , "eg QE2" , "Transport as on sea-going vessel" , "Navigable vessel" .)
