Sailor's on way out of the country (6)
I believe the answer is:
abroad
'out of the country' is the definition.
(I've seen this before)
'sailor's on way' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'on' means one lot of letters go next to another.
'way' becomes 'road' (road is a kind of way).
'ab'+'road'='ABROAD'
(Other definitions for abroad that I've seen before include "in the field" , "Europe, for example" , "At large - overseas" , "Stare lecherously at (someone)" , "Away in another country" .)
