Cruise ship damaged Nile River (5)
I believe the answer is:
liner
'cruise ship' is the definition.
(I've seen this before)
'damaged nile river' is the wordplay.
'damaged' indicates anagramming the letters.
'river' becomes 'r' (abbreviation).
'nile' with letters rearranged gives 'line'.
'line'+'r'='LINER'
(Other definitions for liner that I've seen before include "cruise vessel" , "cover for interior" , "Large passenger or cargo ship travelling on regular route" , "boat" , "Removable inner skin or large passenger ship" .)
