Gulf of Bothnia#
Sampo Ajos, Finnland , a massively built icebreaker, was built in 1960 in Helsinki and for nearly thirty years it kept the northern part of the Gulf of Bothnia open for shipping in winter. The home port of Sampo is Ajos in Kemi. During the summer time Sampo stays in its home port but during the wintertime it makes tourist cruises in the Gulf of Bothnia.
