'sailing' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'away for a look we hear' is the wordplay.
'away' becomes 'off' (synonyms).
'for' becomes 'to' (eg both can mean 'in the opinion of').
'a look' becomes 'see'.
'we hear' indicates a 'sounds like' (homophone) clue.
'see' sounds like 'sea'.
'off'+'to'+'sea'='OFF TO SEA'
