Wise Men peer for moving ship (11)
I believe the answer is:
minesweeper
'ship' is the definition.
(minesweeper is a kind of ship)
'wise men peer for moving' is the wordplay.
'for moving' indicates anagramming the letters.
'wise'+'men'+'peer'='wisemenpeer'
'wisemenpeer' anagrammed gives 'MINESWEEPER'.
(Other definitions for minesweeper that I've seen before include "Warship" , "In the main, clearer" , "Naval vessel" , "PC game" , "One removing bombs" .)
