Tough Boats

Travel Channel has already brought you the toughest trains operating around the world – now we turn our attention to Tough Boats! This series explores some of the most fascinating and hard-core boat journeys on the planet. We'll also look at the way boats have been forced to adapt in order to take on the ever-changing global terrain. From travelling down one of the remotest stretches of the Amazon in Peru, to searching for polar bears on a specially ice-strengthened vessel around the world's northernmost inhabited islands, Tough Boats travels where few boats have gone before!
