Small sailing boat (6)
I believe the answer is:
dinghy
'small sailing boat' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for dinghy that I've seen before include "Small boat propelled with oars" , "Small open boat, maybe a rubber inflatable" , "Small boat, may be a rubber inflatable" , "Light rowing boat" , "craft" .)
