Part of the ship said to be holed (4)
I believe the answer is:
hold
'part of the ship' is the definition.
('hold' is part of 'ship')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for hold that I've seen before include "Nelson?" , "See 12" , "Contain" , "Maintain" , "Have or possess" .)
