Stick duck in boat (5)
I believe the answer is:
canoe
'boat' is the definition.
(canoeing is a kind of boating)
'stick duck in' is the wordplay.
'stick' becomes 'cane' (cane is a kind of stick).
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'in' is an insertion indicator.
'cane' going around 'o' is 'CANOE'.
(Other definitions for canoe that I've seen before include "River craft" , "Narrow paddle boat" , "A dugout" , "Boat that's paddled" , "Small and light boat, pointed at both ends" .)
