Ship caught, run astern (5)
I believe the answer is:
craft
'ship' is the definition.
(I've seen this before)
'caught run astern' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'run' becomes 'r' (cricket abbreviation).
'astern' becomes 'aft' (I've seen this in other clues).
'c'+'r'+'aft'='CRAFT'
(Other definitions for craft that I've seen before include "Workmanship" , "Vessel for a skilled occupation" , "Boat; skill" , "SECOND PART OF 23" , "Vehicle for water or air" .)
