German in ship chasing British monarch (8)
I believe the answer is:
berliner
'german' is the definition.
(Berliner is an example)
'ship chasing british monarch' is the wordplay.
'ship' becomes 'liner' (liner is a kind of ship).
'chasing' says to put letters next to each other.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'monarch' becomes 'er' (abbreviation for Elizabeth Regina).
'b'+'er'='ber'
'liner' after 'ber' is 'BERLINER'.
'in' acts as a link.
(Other definitions for berliner that I've seen before include "capital chap" , "Citizen of Germany's capital" , "German capitalist" , "European citizen < in trio" , "'Ich bin ein . . . . . . . .' (JFK)" .)
