One who decorates mooring rope (7)
I believe the answer is:
painter
I believe this is a double definition.
'one who decorates' is the first definition.
(eg someone painting a house)
'mooring rope' is the second definition.
(rope for mooring a boat)
(Other definitions for painter that I've seen before include "Matisse, maybe" , "Bacon, perhaps" , "Eg, Rembrandt" , "Sutherland?" , "One who has a brush" .)
