From the other thread:
From Principles of Yacht Design, Lars Larsson and Rolf Eliasson, third edition, 2007, pp 95:
"A final point to mention is the balance between the forward and aft halves of the hull. Many modern yachts have very full stern sections, while the forward sections are very sharp. This may be good for the surfing abilities of the hull, but it is not good for the course stability when rolling. When the hull heels over, the centre of buoyancy moves much more sidewards in the stern than in the bow. The force required to move the volume of water sidewards comes from the hull, which by law of action and reaction is affected by the same force from the water, but in the opposite direction. The stern is thus affected much more than the bow, and the hull changes its course in the heeling direction. This happens, of course, both to starboard and port, and the hull becomes difficult to keep on course."
