Wood and metal off the boat (6)
I believe the answer is:
ashore
'off the boat' is the definition.
(I've seen this before)
'wood and metal' is the wordplay.
'wood' becomes 'ash' (ash is a kind of wood).
'and' is a charade indicator (letters next to each other).
'metal' becomes 'ore' (I have seen 'Raw metal ' mean 'ore' so perhaps 'metal' could also mean 'ore').
'ash'+'ore'='ASHORE'
(Other definitions for ashore that I've seen before include "Returned to land" , "Home for the sailor" , "Hoarse (anag)" , "Toward land from the sea" , "Hoarse being no longer at sea" .)
