“Planing” is Bunkum – Myths about Planing, Displacement and semi Planing

It always bugged me about how people said that some powerboats and fast sailing dinghies would “plane” to reach high speed. But multihulls reach higher speed, but they “don’t plane”. It’s illogical to have two different explanations. Also how a classical “displacement hull” go much faster on an ocean wave. Theory says it has a speed limit no matter the power you throw in. I worked out a reasonable explanation for all this but it shows “planing” does not exist.
