I probably should have limited the discussion to round bilge.
Anywho..it would seem intuitive that beam coupled with ballast down low give less roll but I'm not 100% certain that this is the case or that it is all of the case and that other factors also come into play.
Thinking of moored boats at our marina I've noticed quite beamy boats that seem to move around a lot more than narrower ones while our multi chined hull does not seem to be inherently more stable than a friends round bilge version of the same boat.
I'm thinking that the curve of the bilge (is that the correct expression ?) and buoyancy fore and aft may also have an impact, so that a wider stern might limit rolling while a very fine stern encourage it.
To that end would it follow that a typical IOR hull (fine bow, pinched in stern) be more of a roller than say a modern wide arsed jobby ?
