Country is fine away from the coast (7)
I believe the answer is:
finland
'country' is the definition.
(I know that Finland is a country bordering the Baltic Sea)
'fine away from the coast' is the wordplay.
'fine' becomes 'f' (abbreviation).
'away from the coast' becomes 'inland' (inland means away from the coast).
'f'+'inland'='FINLAND'
'is' acts as a link.
(Other definitions for finland that I've seen before include "Northern country" , "Sibelius's country" , "European country, capital Helsinki" , "North European country" , "Scandinavian country" .)
