You consider information from someone with zero knowledge in stability or structural design to be useful? More experienced boat design people would consider that laughably gullible!
Surviving 16 days pounding in up to 12 ft surf on a Baja lee shore, pounding across 300 yards of Fijian coral reef, T-boning a steel barge at hull speed, colliding with a freighter in Gibraltar, decades of ocean cruising in all conditions, without a single structural failure at sea, and a single season passage thru the NW passage, all with no structural damage whatever, is far more accurate that any calculations you could ever come up with.
Yet those who claim that such boats are not structurally strong enough , buy and cruise in boats which would have broken up in minutes in the same conditions, proving that they are definitely not the sharpest tools in the shed!
Perhaps it is time you gave NASA a call, and informed them that they can get rid of their wind tunnels and structural testing to destruction, as your computer is more accurate.
The stability curve of my boats is posted on the origami boats site. Have someone who can read English, interpret the last sentence for you.
