Boat's propeller from liner good at sea (9)

I believe the answer is:

gondolier

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

'boat's propeller' is the definition.
I know that 'boat' relates to this answer. I also know that both the answer and definition are singular nouns

'liner good at sea' is the wordplay.
'at sea' indicates an anagram.
'liner'+'good'='linergood'
'linergood' anagrammed gives 'GONDOLIER'.

'from' acts as a link.

Can you help me to learn more?

(Other definitions for gondolier that I've seen before include "Propeller of Venetian boat" , "One to move over water" , "Punter" , "Venetian boater" , "to leave Red Lion disorientated" .)

I've seen this clue in The Independent.
