Rowboat implements (4)
I believe the answer is:
oars
'rowboat implements' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oars that I've seen before include "Soar around the rowers" , "Implements to propel a boat" , "Rowing blades" , "Boating implements" , "Implements of propulsion on water" .)
