Artist keeps a boat by the bank (7)
I believe the answer is:
painter
This clue is a double definition.
'artist' is the first definition.
(I know that painter is a type of artist)
'keeps a boat by the bank' is the second definition.
(I've seen this before)
(Other definitions for painter that I've seen before include "Sutherland?" , "Bacon, perhaps" , "One who has a brush" , "Artist - rope for boat" , "someone like Monet" .)
