Inspired by the ongoing threat to UK oil tankers at the moment I decided to find out just how big a ship the Iranians could possibly hijack, which brought me to this page. The winner was always going to be a ULCC (Ultra Large Crude Carrier) also known as an oil tanker :p
The biggest is the Jahre Viking, formerly known as the Knock Nevis, pictured below:
|Tonnage:||260,941 GT (214,793 NT)|
|Length:||458.45 m (1,504 ft)|
|Beam:||68.8 m (226 ft)|
|Draught:||24.611 m (81 ft)|
|Speed:||16 knots (30 km/h; 18 mph)|
Also found this old clip of Jeremy Clarkson giving everybody a tour of this very same ship..
