Might get them on board to take ride around vineyard (4)
I believe the answer is:
navy
'might' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.

I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for navy that I've seen before include "Fleet of ships" , "Senior service" , "military arm" , "Ships-of-war" , "A dark blue; service" .)
