Narrative:
Departure routing-confusion with nassau int'l controllers over departure route. Believed route was BR55. When ZMA informed route was BR57, we were several miles off course. ZMA amended my route to BR55 direct go bimini VOR after discovery of incorrect route. Communication with nassau controllers is difficult due to their abrupt attitude and language variation.

Title: SMT FLIES INCORRECT OCEANIC ROUTE DUE TO MISUNDERSTANDING OF FOREIGN CTLR'S CLRNC DELIVERY.
Narrative: DEP ROUTING-CONFUSION WITH NASSAU INT'L CTLRS OVER DEP ROUTE. BELIEVED ROUTE WAS BR55. WHEN ZMA INFORMED ROUTE WAS BR57, WE WERE SEVERAL MILES OFF COURSE. ZMA AMENDED MY ROUTE TO BR55 DIRECT GO BIMINI VOR AFTER DISCOVERY OF INCORRECT ROUTE. COM WITH NASSAU CTLRS IS DIFFICULT DUE TO THEIR ABRUPT ATTITUDE AND LANGUAGE VARIATION.
