'moves' is the definition.
(whip is a kind of move)

'start work on a shipwreck' is the wordplay.
'start' suggests taking the first letters.
'on' says to put letters next to each other.
'a shipwreck' becomes 'hips' (anagram of 'ship').
The initial letter of 'work' is 'w'.
'w'+'hips'='WHIPS'

'fast to' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
