1. Perhaps a mast-top winglet system would actually work in wave-piercing cats like A-class cats: Since pitching is not helpful to this concept, the wave-piercers seem to do it less.
2. Has anyone actually tried measuring pitching in wave piercers vs lets say- Marstrom conventional hull shapes?
This could be done from a digital video tape or a CD: at 1 second intervals, measure angle of mast rake for each boat. They should be sailing parallel to another to weather in appreciable waves for several minutes.
Put data on Excel sheet, (or by some magic maths which I do not possess)---determine which pitches less, and how much less!
