Refuse boat (4)
I believe the answer is:
junk
I believe this clue is a double definition.
'refuse' is the first definition.
(I've seen this in another clue)
'boat' is the second definition.
(type of Asian ship)
(Other definitions for junk that I've seen before include "ship" , "Abandon" , "Transport" , "Clutter - Chinese boat" , "Schlock" .)
