Club's new boat vandalised (5)
I believe the answer is:
baton
'club's' is the definition.
(I've seen this before)
'new boat vandalised' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'vandalised' is an anagram indicator.
'n'+'boat'='nboat'
'nboat' anagrammed gives 'BATON'.
(Other definitions for baton that I've seen before include "Police (or conductor's) stick" , "Conductor's rod" , "It's passed in a relay race" , "Club, stick" , "Piece of equipment" .)
