'cast loose' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'a raft-tide's going out' is the wordplay.
'going out' is an anagram indicator (out can mean wrong or inaccurate).
'raft'+'tides'='rafttides'
'rafttides' with letters rearranged gives 'SET ADRIFT'.

'in' is the link.
