Be right with ship that's German (8)
I believe the answer is:
berliner
'that's german' is the definition.
(someone from Berlin)
'be right with ship' is the wordplay.
'right' becomes 'r' (common abbreviation).
'with' means one lot of letters go next to another.
'ship' becomes 'liner' (liner is a kind of ship).
'be'+'r'+'liner'='BERLINER'
(Other definitions for berliner that I've seen before include "capital chap" , "Person from the German capital" , "'Ich bin ein . . . . . . . .' (JFK)" , "Citizen of Germany's capital" , "JF Kennedy said he was one, Marlene Dietrich was one" .)
