A long way off a seafaring centre (4)

I believe the answer is:

afar

'a long way off' is the definition.
(I've seen this before)

'a seafaring centre' is the wordplay.
'centre' indicates the central letters.
The central letters of 'seafaring' are 'far'.
'a'+'far'='AFAR'

(Other definitions for afar that I've seen before include "quite some distance" , "Many miles away" , "long way back" , "Way-out" , "Not in this neighbourhood" .)

I've seen this clue in The Globe and Mail.
