Hi I've been thinking about the way water flows around, or should I say up, along and down a displacement hull. This has lead me to a hull design idea based on the hull displacing water into a single wave as it passes. The cross section area at any point along the hull would be equal to the cross section of the displaced wave. Disigned properly, for a specific speed, the whole length of the hull would produce just one single wave length instead of the usual bow wave and stern wave. What I need for this is a formulae relating wave length, amplitude and velocity. Anyone know of one? I don't really know how this would work out, it's probably been done before, anyone know of that either?
