Good in nude displaying craft (5)
I believe the answer is:
barge
'craft' is the definition.
(barge is a kind of craft)
'good in nude' is the wordplay.
'good' becomes 'g' (abbreviation).
'in' means one lot of letters goes inside another.
'nude' becomes 'bare' (synonyms).
'g' put within 'bare' is 'BARGE'.
'displaying' is the link.
(Other definitions for barge that I've seen before include "Sort of board" , "Canal-boat" , "Narrow boat" , "Move roughly; boat" , "Push - boat" .)
