Boat capsized in ocean (5)

I believe the answer is:
canoe
'boat' is the definition.
(canoe is a kind of boat)
'capsized in ocean' is the wordplay.
'ocean' can be anagrammed to 'CANOE'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for canoe that I've seen before include "Small boat for paddling" , "Ocean (anag)" , "Small and light boat, pointed at both ends" , "River craft" , "Primitive boat" .)
