Chaplains at sea making way for sailors (4,5)
I believe the answer is:
ship canal
'way for sailors' is the definition.
'chaplains at sea' is the wordplay.
'at sea' indicates anagramming the letters.
'chaplains' anagrammed gives 'SHIP-CANAL'.
'making' acts as a link.
(Other definitions for ship canal that I've seen before include "Manchester has one" , "crafty way?" , "course for sailors" , "Navigable waterway" .)
