The lightweight of the TS Kennedy is 12,892 tons.
A ship's lightweight is the actual weight of the ship without cargo, fuel, passengers, etc.
If you could empty the TS Kennedy and place her on a scale (which, of course, you can't), her weight would be 12,892 tons.
A white rhinoceros weighs approximately 2 tons. You'd need 6,446 white rhinoceroses to equal the lightweight of the TS Kennedy.
That's a lot of white rhinoceroses! The TS Kennedy is a heavy ship.
