Vast liner at sea breaks (9)

I believe the answer is:

intervals

'breaks' is the definition.

'vast liner at sea' is the wordplay.
'at sea' is an anagram indicator.
'vast'+'liner'='vastliner'
'vastliner' anagrammed gives 'INTERVALS'.

(Other definitions for intervals that I've seen before include "Intermissions" , "Periods of time between parts of a play" , "Times between acts" , "Net's viral (anag.)" , "Rests" .)

I've seen this clue in The Telegraph.
