Platform for disembarking (7,5)
I believe the answer is:
landing stage
'platform for disembarking' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for landing stage that I've seen before include "Platform for disembarking" , "berth" , "on quayside - with 42a" , "where cargos unloaded" , "Place to board boat" .)
