During the summer of 1975, on the Mecklenburg's coastline, a sport boat w/ 4 persons aboard managed to make its way free to the high sea, thanks to the cover of dusk, escaping security forces from the GBK in the process.
Despite DDR's efforts, the sport boat managed to get to BGS's patrol boat. The East Germans asked to be brought onboard, as they wanted to go to the West.
One hour later, 2 GBK rushed after the Duderstadt and tried to stop her. However, the BGS patrol boat managed to escape, aided by already being in international waters near west Germany.
