Caught by State Coastal Patrol Boat (6)
I believe the answer is:
cutter
'patrol boat' is the definition.
(I've seen this in another clue)
'caught by state coastal' is the wordplay.
I cannot really understand how this works, but
'caught' could be 'c' (cricket abbreviation) and 'c' is found within the answer.
'state' could be 'utter' (both can mean to say) and 'utter' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cutter that I've seen before include "Vessel (but not a clipper!)" , "Slicing tool of fast sailing ship" , "Sailing boat - knife, perhaps" , "One working with Ruby possibly" , "A scissors, say, or a small ship" .)
