Boat detailed to get container for fruit (6)
I believe the answer is:
punnet
'container for fruit' is the definition.
(eg a punnet of strawberries)
I can't explain the rest of the clue.
(Other definitions for punnet that I've seen before include "Small basket for measuring fruit" , "Small basket for 13 Across (6)" , "Shallow fruit basket" , "Fruit 18 Down" , "Strawberry etc. container" .)
