Wobbly craft (5)
I believe the answer is:
canoe
'wobbly 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 "Narrow paddle boat" , "Kayak-like boat" , "Small and light boat, pointed at both ends" , "Light boat propelled by paddle(s)" , "Hunting vessel originating in Haiti" .)
