Inducement to serve in unhappy ship (6)
I believe the answer is:
bounty
This clue is a double definition.
'inducement to serve' is the first definition.
'unhappy ship' is the second definition.

'in' is the link.
(Other definitions for bounty that I've seen before include "William Bligh's ship" , "One pursuing fugitives for a reward" , "blood money" , "Christian took responsibility for this" , "naval ship . . ." .)
