Back turned on beach, briefly, in Scottish town (9)

I believe the answer is:

stranraer

I'm a little stuck... Click here to teach me more about this clue!

'scottish town' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for stranraer that I've seen before include "Scottish ferry terminal" , "Scottish town with ferries to N Ireland" , "Scottish ferry port" , "Scottish port for Belfast ferries" , "Scots port serving Northern Ireland" .)

I've seen this clue in The Times.
