Led onto the vessel, looked furious (4)
I believe the answer is:
scow
'led' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scow that I've seen before include "Vessel" , "Flat-bottomed boat for cows" , "Unpowered freight barge" , "Wide-beamed dinghy" , "Maybe lighter" .)
