It isn't really required to do this. Under IOR a method was developed
for estimating a yachts stability from small changes in trim angle
when moving a weight a certain longitudinal distance. They are still
pretty good estimators of stability, particularly if you yacht wasn't
designed to fool them. Again, L&E discuss the methods and work and
example.
