Canoe (5)
I believe the answer is:
kayak
'canoe' is the definition.
(I know that kayak is a type of canoe)
This is all the clue.
(Other definitions for kayak that I've seen before include "Boat used by 23 Across" , "Type of canoe" , "Lightweight canoe" , "Palindromic canoe used by eskimos" , "A palindromic canoe for eskimo" .)
