Guys, bottom line is this... listing due to body weight is a matter of physics. There is a direct porportional relationship between the mass of the vessel and the mass of any object placed within the vessel. The closer the two are in a mass versus mass relationship, the more the interfearance between the two absolutes will be.
Unfortunately guys, the way to minimize listing on any vessel is either decrease the mass of the Captain (if he's running solo) or get a vessel that exhibits more mass (i.e. bigger boat).
Unfortunately, for those of us with limited cash to increase the mass of our boats (size) the only option for us is to add ballast to the port side... or... lose weighat. The later is a bummer, counter productive to the American way of life, and to the known physical law of nature... "Bigger is better"! I say pay the arabs for gas and add 50# ballast to the port side.
This is the American way.... Hooo Rah!
