25.5 is wider than Cherubini h25
The capsize screen converts displacement into volume, then takes the cube root of the volume (this is like converting the volume of displaced water into a cube shape, and measuring one of the edges). That edge or cube root is then compared to the beam. If the beam is more than twice the side of the cubis displacement, the boat is judged to have high form stability. That is, a wide boat resists turning over because it is wide. This allows more cabin room, and sometimes more sail area for a given displacement. That means a faster boat that you wouldn't want to take too far from the coast. That's because if the wider boat is rolled by a breaking wave higher than its beam, its more likely to stay inverted for a longer time. This is the trend of more modern boats. They are beamier, lighter, and more roomy. They will go faster in light air. That's what most of us want for our day sailing, and coastal cruising. The boats of the 70's of which the Cherubini designs are excellent examples tend to be more capable in rough weather, and probably a little slower in light air.
