Carl-
I was actually thinking the "ideal" planing cat might be rather narrow beam between the hulls with wide racks for righting moment and the intent of the design to have flat surfaces when the boat is level utilizing BOTH hull sterns (and a possibly retractable flat "panel" that would drop down or extend down from the rear beam between the hulls??) to plane when conditions are good for planing but the ability to "fly" one of the hulls when planing conditions are poor (due to narrow inter hull beam, tall powerful rig, and ability to bring crew weight where needed- even to leeward!) and so when the hulls are canted (at that 12 degrees or whatever) the in water hull shape would more nearly approximate the current designs (long, narrow and circular)-
What do you think??
