Dinghy or kayak (4)
I believe the answer is:
boat
This clue is a double definition.
'dinghy' is the first definition.
(I've seen this in another clue)
'kayak' is the second definition.

(Other definitions for boat that I've seen before include "Contest on the Thames" , "Floating vessel" , "Eg, coracle" , "See 1" , "See 18" .)
