So the math is this: with the Cat, there is only one 1,500 lb hull in the water, and one being lifted, moment arm of 20 feet, or 30,000 ft. lbs. And with the tri , we have one hull at 1,000 lbs, with a 20 foot arm and one at 1,000 lbs with a 10' righting arm. So the tri has 1,000 x 10' (10,000 ft. lbs) plus 1,000 lbs. x 20' (20,000 ft. lbs) which also equals 30,000 ft. lbs, correct?

BUT....the lone 1,000 lb. tri hull still in the water is now supporting the 2,000lbs. of two hulls up, which should make it sink lower in the water, where as the single cat hull, is only supporting 1,500 lbs. which should make it float a little higher, correct? And do we assume the cat's hulls are a little bigger, since they each weigh 50% more than the tri hulls? And since we just decided the two are equal, why do they build the tri's wider than the cats? Or should I be asking why the cats aren't as wide as the tri's? Why is a 60' racing cat not 60' wide, like a racing tri?
