NSF supercomputer centers are collaborating towards a "metacenter.".    From Wordnik.com.  [Fccset Initiatives In The Fy 1994 Budget] Reference

For a vessel with a given displacement, the metacenter and center of gravity being known, it is easy to lay off in the form of a diagram its stability or power of righting for any given angle of heel.    From Wordnik.com.  [Scientific American Supplement, No. 385, May 19, 1883] Reference

The curve may be constructed in the following manner: Having found by calculation the position of the transverse metacenter, M, for a given displacement -- Figs. 1 and 2 -- the metacentric height, G M, is then determined either by calculations, or more correctly by experiment, by varying the position of weights of known magnitude, or by the stability indicator itself.    From Wordnik.com.  [Scientific American Supplement, No. 385, May 19, 1883] Reference
