[Public-list] Longitudinal Center of Gravity

Mike,
I looked at the lines plan on Roger's site and I think the 16' 1" measurement is the Lateral Center of Buoyancy. I'm looking for the Longitudinal Center of Gravity. There are two Centers of Gravity measurements the Verticle Center of Gravity and the Longitudinal Center of Gravity. The centers of gravity are what I am interested in to make the calculations to design the hoist to lift the boat out of the water. Jack probably determined what these centers of gravity measurements were. Do you think you can get these?
Thanks,
John
