Day ending often in scandal, where sailors may be found (7)
I believe the answer is:
frigate
'where sailors may be found' is the definition.
(frigate is a type of ship)
'day ending often in scandal' is the wordplay.
'day' becomes 'fri' (abbreviation for Friday).
'ending often in scandal' becomes 'gate' (Watergate etc).
'fri'+'gate'='FRIGATE'
(Other definitions for frigate that I've seen before include "Type of warship" , "Warship; -- bird" , "Naval escort vessel" , "US warship" , "Ship" .)
