Venetian boatman (9)
I believe the answer is:
gondolier
'venetian boatman' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for gondolier that I've seen before include "Venetian waterman" , "Venetian boater" , "Propeller of Venetian boat" , "One to move over water" , "Traditional boatman of Venice" .)
