chine walk

[Fr. Frank]

is it possible that the nose actually is not high enough and the boat is running too flat thereby causing the chime walk ?

The chine walk may be exaggerated by a nose high position, but probably not by a stern high or flatter planing pitch, unless only one side of the center deadrise angle has some serious hook in it, like 1/16" to 1/8" per foot in the aftermost 5' of the hull.

As the hull speed increases, it tries to find the point of least resistance, and rises up out of the water until only the aftermost center of the hull is the primary planing surface. The problem with that is the transitions, and the fact that a pure V is inherently unstable. It wants to fall off to one side or the other and plane on the smaller flat surface on one side of the V, rather than the whole V. A VDH hull running flatter, or nose lower, will be more stable than one running nose high, because it will plane on more than just the center angle.
