Bounty, a big ship (7)

I believe the answer is:

largess

'bounty' is the definition.
(I've seen this before)

'a big ship' is the wordplay.
'a big' becomes 'large' (I've seen this before).
'ship' becomes 'ss'.
'large'+'ss'='LARGESS'

(Other definitions for largess that I've seen before include "Generosity" , "Bounty" .)

I've seen this clue in The Times.
