Trash sailing vessel (4)
I believe the answer is:
junk
This clue is a double definition.
'trash' is the first definition.
(junk is a kind of trash)
'sailing vessel' is the second definition.
(thesaurus)
(Other definitions for junk that I've seen before include "Clutter - Chinese boat" , "Sailing vessel; rubbish" , "scrapped?" , "ship" , "Schlock" .)
