Here are some stability calculations and other numbers who Guy Lilljegren kindly has provided me with. There are three sets for center of gravity for 5, 10 and 15 centimeters above the waterline. Hopefully the center of gravity will come out at 10 centimeters above the waterline, but only the Gods know for shore. The numbers are really too small to reed but if you click on the pictures, first one time, them again, they get bigger and bigger.
