The sea area for a quick catch? (7)

I believe the answer is:

fastnet

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

'the sea area' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'quick catch?' is the wordplay.
'quick' becomes 'fast' (similar in meaning).
'catch?' becomes 'net' (net can mean to catch).
'fast'+'net'='FASTNET'

'for a' acts as a link.

Can you help me to learn more?

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

I've seen this clue in the Evening Standard.
