The two double-hulled boats displaced 2,730 tons on the surface and 3,900 underwater on a length of .
Each boat displaces 3,051 tonnes when surfaced, and 3,353 tonnes when submerged.
Fully outfitted and fueled, the boats could displace much more.
Provided that the boat displaces 1,000 pounds of water before the whole thing is submerged, the boat floats.
The boat displaced 42 tons, was 25 meters long and had 12mm of armor on its "citadel" protecting the engines and other vitals.
A floating boat displaces its weight in water.
The boat displaces a total of 410 pounds.
If the boat can displace more Newtons (or pounds) of water than the boat weighs, then the boat can float.
Because a boat displaces its own weight in water, the system should be balanced, and a small amount of energy is required to start the boats moving.
When any boat displaces a weight of water equal to its own weight, it floats.
