日本Britain, is an island. Surrounded by a cold and unforgiving sea. For centuries it protected us from attack. But to prosper and thrive, we would need to do more than hide behind her salt water shield. Britain needed brave men, willing to venture out into the unknown and she needed good boats to take them there. I've spent my life at sea. Now I'm going to take passage on six boats that together, tell the story of modern Britain. Built for exploration, war, fishing, industry and our very survival. These are the boats which built Britain, and changed the way we live - forever.
