Huge ship with the last bounty (8)
I believe the answer is:
largesse
'bounty' is the definition.
(I've seen this before)
'huge ship with the last' is the wordplay.
'huge' becomes 'large' (similar in meaning).
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'with' means one lot of letters go next to another.
'last' indicates one should take the final letters.
The final letter of 'the' is 'e'.
'large'+'ss'+'e'='LARGESSE'
(Other definitions for largesse that I've seen before include "Les rages at the distribution of gifts" , "Bounty, gift" , "Generosity in bestowing gifts" , "Generous offering" , "Generosity in giving gifts" .)
