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

'canal boatman' is the definition.
'gondolier' can be an answer for 'boatman' (gondolier is a kind of boatman). I am unsure of the 'canal' bit.

'wreck good liner' is the wordplay.
'wreck' indicates an anagram.
'good'+'liner'='goodliner'
'goodliner' anagrammed gives 'GONDOLIER'.

'might' is the link.

Can you help me to learn more?
