We will let it weigh 400 pounds including everything. So the basic platform generates 400 pounds times 8.5ft/2 = 1700ftlbs of righting moment and that turns into 1700/300 = 5.67 ftlbs of righting moment per sqft of sail area.
Bill,
How is it calculated that a Tornado Sport utilizes 24.3ftlbs per square foot of sail area?
