As you know, at the turn of the tide, the waters confined between the Faroe and Lofoten Islands rush out with irresistible violence. They form a vortex from which no ship has ever been able to escape. Monstrous waves race together from every point of the horizon. They form a whirlpool aptly called “the ocean’s navel,” whose attracting power extends a distance of fifteen kilometers. It can suck down not only ships but whales, and even polar bears from the northernmost regions.
