Olympics vehicle since 1936 (5)
I believe the answer is:
canoe
'olympics vehicle since 1936' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for canoe that I've seen before include "Small and light boat, pointed at both ends" , "Kayak-like boat" , "Simple boat" , "Light boat propelled with paddle" , "River craft" .)
