Regarding flared bows with overhangs and pitching, I understand your point of view but wonder if there is a "sweet" spot, so to speak, where that style of boat will pitch excessively. Once the distance between waves is longer than the boat length then as the wave approaches wouldn't the entire boat just lift and ride up the wave face? At some point in building seas the waves must become like hills that the boat must go up, not like short wavelength bumps that cause pitching. That makes it the pitching sound like a problem on certain boats only when the wavelength and hull length work together to create the pitching moment. On my boat, their is certainly a point at which the boat pitches most but that is on relatively small waves that are very close together (powerboat wakes).
