BBC Jahre Viking Ship, Largest Man Made Moving Machine! Jeremy Clarkson's Extreme Machines 

I love how he points out that they are, in fact, not driving a car on land.

Imagine if the Olympic-class ships were bigger than this boat

This ship had many names Seawise Giant, Jahre Viking, Knock Nevis. She was scrapped in 2010.

This gigantic oil tanker had truly frightening dimensions: It was 458.45 meters long, 68.86 meters wide and when fully loaded it had a draft of 24.61 meters. These measures prevented it from passing through many canals, such as the Panama Canal or Suez Canal. It had a 50,000 horsepower engine, a 9-meter diameter propeller weighing 50 tons, the rudder blade was 11 meters long, 14 meters high weighed 250 tons and it had a 36-ton anchor. The anchor can still be seen outside the Hong Kong Maritime Museum

Im pretty sure this is the largest engine ever made and the biggest propeller ever made.

Imagine if the blue whale was that size

Which maritime company owe's this ship?

Who paid for this?
