Ocean-tossed paddle boat (5)
I believe the answer is:
canoe
'paddle boat' is the definition.
(I've seen this in another clue)
'ocean-tossed' is the wordplay.
'tossed' indicates an anagram.
'ocean' is an anagram of 'CANOE'.
(Other definitions for canoe that I've seen before include "Narrow paddle boat" , "Kayak, for instance" , "Primitive boat" , "Simple boat" , "Small boat for paddling" .)
