Deserted port (4)

I believe the answer is:

left

I believe this is a double definition.

'deserted' is the first definition.
(I've seen this in another clue)

'port' is the second definition.
(port is the left side on a boat)

(Other definitions for left that I've seen before include "Possibly radical" , "political group" , "It's not right" , "Departed or bequeathed" , "The side of socialism" .)

I've seen this clue in The Irish Independent.
