Light craft (5)
I believe the answer is:
canoe
'light craft' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for canoe that I've seen before include "Kayak-like boat" , "Boat (that can be dug out!)" , "Small and light boat, pointed at both ends" , "Primitive boat" , "Light boat propelled with paddle" .)
