Huge Hovercraft

S1, E6: The Canadian Coast Guard, which protects the beachfront city of Vancouver, is in desperate need of a new breed of rescue vehicle. The solution is the AP1-88 Hovercraft, a 100-foot marine machine. The challenge is it's still being assembled in Southampton in a factory 9,000 miles away. Follow a team of engineers as they attempt to build and haul it across the Atlantic Ocean, through the Panama Canal, and up the West Coast of the U.S. and Canada without incident.
