Cruise ship's tarry? Not good! (5)
I believe the answer is:
liner
'cruise ship's' is the definition.
(I've seen this before)
'tarry? not good' is the wordplay.
'tarry?' becomes 'linger' ('linger' can be a synonym of 'tarry').
'not' suggests deleting specific letters.
'good' becomes 'g' (abbreviation).
'linger' with 'g' taken away is 'LINER'.
(Other definitions for liner that I've seen before include "Craft" , "bin-bag?" , "Cosmetic; fine paintbrush" , "It covers bin's interior" , "Passenger ship - bin bag" .)
