A short month in a yacht basin (6)

I believe the answer is:

marina

'yacht basin' is the definition.
(I've seen this in another clue)

'a short month in a' is the wordplay.
'a short month' becomes 'Mar' (short for March; 'short' suggests an abbreviation).
'mar'+'in'+'a'='MARINA'

(Other definitions for marina that I've seen before include "Dock for pleasure craft" , "where yachts moor" , "Airman (anag)" , "seaside area" , "part of harbour?" .)

I've seen this clue in The Times.
