It will be less detrimental on a narrow boat
The best example you can find of those type hulls are on the last America's cup mono-hull where on the last boats the hull has become more box like but where a hard chine was avoided. That was a desperate attempt to gain hull form stiffness on such a narrow boat (and it worked) but if they would not have been limited by max beam they would have just made a beamier boat.
