Boatman travelling old region (9)
I believe the answer is:
gondolier
'boatman' is the definition.
(gondolier is a kind of boatman)
'travelling old region' is the wordplay.
'travelling' is an anagram indicator.
'old'+'region'='oldregion'
'oldregion' with letters rearranged gives 'GONDOLIER'.
(Other definitions for gondolier that I've seen before include "Venetian boatman" , "Traditional boatman of Venice" , "One to move over water" , "Venetian boater" , "Venetian waterman" .)
