A vessel's displacement of course varies with how much stuff you load the hull with: it amounts basically to the total mass supported by the buoyancy of the submerged hull. In terms of the different conditions of loading defined in that Wikipedia article, I suppose that what i want is the difference between "loaded displacement" and "normal displacement" (or maybe "light displacement, though that would involve me in having to estimate the mass of the passengers, crew, and stores.
