Avred Fuchs Sails the North Atlantic Greenland to Germany looks to be a great documentary. I have only found Part 1 and Part 5 of the five part series online. I send a note to Mr. Fuchs himself to try and find where I might be able to purchase the entire film, but he has yet to respond.
From Free Documentary: Sailing Across the North Atlantic is a film about Arved Fuchs and his team on their most recent expedition across the North Atlantic begins on the 80-year-old sailing ship “Dagmar Aaen”, from Greenland’s west coast, via Newfoundland, Nova Scotia, Ireland and Scotland to the North German coast. It is a journey full of unforgettable experiences: unspoiled nature, rugged coasts, remote islands and extraordinary people who live with and off of the sea. For more than 30 years, German Arved Fuchs has undertaken ships expeditions to the most remote regions of our planet. He is mostly attracted to ice. There, on the west coast of Greenland, the cutter Dagmar Aaen, spent seven long winter months. This is where the five part series begins, which will come to an end after 12.000 nautical miles (ca. 22.000 kilometres) and more than four months later in the native North Sea.
