Todd, When you say 1 foot away or 5 1/2 feet away, what is it away from? I can not get your numbers to work, even allowing for rough approximations. Cheers, ...

Peter, What Todd has done is place a bathroom scale under the ama. Then, he has taken note of the weights when seated at different locations on the crossbeam....
The ama weight is part of the equation. The main hull is 12'' wide at sheer and keel. I'm 220lbs. From center line the ama is 9' away I was figuring from...

... I like this compromise, Tom. Makes a wholesome hull shape, with most of the sharpie's advantages left in. I agree with you regarding "chine runners,"...

Gary The Ama you describe is something like the one I am busy with, only minus a few of the clever pieces like valves. Two bulkheads divide the Ama into three...
