The height of the TS Kennedy from her the bottom of her hull to her highest, non-removeable point is 119 feet.
When you see a photo of the TS Kennedy at sea, the part of the hull that is below the waterline isn't visible.
The photo below shows the TS Kennedy in drydock.
So how high is 119 feet? Imagine 7 giraffes stacked up one on top of each other. The 7 giraffes would almost match the height of the TS Kennedy.
The giraffe is the tallest animal on Earth. An adult giraffe stands approximately 16.5 feet.
