Ship finds course right behind converted canoe (5,5)
I believe the answer is:
ocean liner
'ship' is the definition.
(ocean liner is a kind of ship)
'course right behind converted canoe' is the wordplay.
'course' becomes 'line' (synonyms).
'right' becomes 'r' (abbreviation).
'behind' is a charade indicator (letters next to each other).
'converted' is an anagram indicator.
'canoe' anagrammed gives 'ocean'.
'line'+'r'='liner'
'liner' put after 'ocean' is 'OCEAN-LINER'.
'finds' acts as a link.
(Other definitions for ocean liner that I've seen before include "Queen Mary, for example" , "Cruise ship" , "Craft" .)
