Shipping forecast area south of the Republic of Ireland between Lundy and Shannon (7)

I believe the answer is:

fastnet

(Other definitions for fastnet that I've seen before include "Rock off Co. Cork" , "shipping forecast area" , "A sea area; a yacht race" , "area next to Lundy" .)

I've seen this clue in The Mirror.
