It’s almost self-evident that more deadrise aft — a sharper hull — is going to ride softer. I say “almost” because other elements come into play. One of these is the width of the chine. If a boat has wide chines, it’s likely to slap more in a chop than another boat with equivalent deadrise and narrower chines. Then there’s the angle of the chines. Some are “flat,” that is, they protrude horizontally from the V of the hull panels. This is in contrast to reversed chines, which angle out from the hull at a downward angle. Again, all things being equal, of two boats with the same width chines, the one with reversed chines will likely be able to maintain a higher speed before pounding.
