Venetian canal boat (7)
I believe the answer is:
gondola
'venetian canal boat' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for gondola that I've seen before include "Boat on Venetian canals" , "Venetian taxi" , "Palmieris' craft" , "Venetian vessel" , "Supermarket display unit" .)
