beam adds stability.

That might be true of small race boats that plane. The big ones do not plane and no displacement hull ever will. The wide bodied sailboats like Hunters and Catalinas are a nightmare in rough seas. The slam and pound rather than slice through the water.
Anyway, if you look at the stern of most mid-size and larger sailboats with true displacement hulls, look down near the waterline. the hull comes to a point. The underwater part of a ocean crossing or rough water sailboat has a canoe shape both fore and aft. Also a narrow beam with a heavy keel takes up less lateral space in the water than a wide beam and so, given the shape of a wave. the narrow beam will be stand more vertical - less surface contact is less likely to follow the contour of the wave.
