Join Steffan as he sets sail around London, glides through historical monuments, and unearths long-forgotten secrets from beneath the waterway

Magic, to a sailor, is harnessing the wind—getting something for nothing—the surprise of a gust, the boon of a side-wind, and the trial of a headwind and best of all, the moment when a change in direction means turning away from the head seas and wind and spray in silence and warmth. In 1969, man flew to the moon and sailed around the world solo. In 2009, sailor and Londoner Steffan Meyric Hughes thought he'd try something a little closer to home and became the first to sail and row around London in a small boat. Along the way, he discovered the history of the great city's future and great secrets of the mysterious Thames: wrecks, bombs, and intrigue. Circle Line is the story of a unique journey on the forgotten waterways of one of the world's greatest capitals; an investigation into the way we live today; and a humorous, moving trip down memory lane.
