Geez guys ... if you are going to discuss the minutia of hull speed and power per can of beer sold per crossing times the square root of the number of Ipads onboard, at least get your basics straight.

How can anyone discuss this stuff without even the most basic understanding of the numbers and terms they are using?

The figure of 2813 has absolutely nothing to do with the weight of the vessel. It is a regulatory number calculated with regard to internal volume.

Subtracting net from gross to come up with a ship's cargo weight is even more preposterous.

Displacement of Elwha is very close to 4000 tons, and the waterline length (the length that matters with regard to hull speed and such) is just under 360 feet. GIGO.

It takes less time to look it up than it does to post what should be very embarrassing nonsense.
