Rudder handle (6)
I believe the answer is:
tiller
'rudder handle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tiller that I've seen before include "Bar used to turn rudder in small boat" , "Means of steering boat" , "Bar that manipulates rudder" , "Handle for turning rudder" , "Rudder's steering handle" .)
