Steve Hill has started the hull plug for an I-400 mold and hopes to finish it this summer. The plans show a fatter hull than the OOP Battlers version, especially forward of amidships. After my experiments with a B/C hull deepened by 1/2" Steve and I concluded the new hull should be 1" deeper than the plans to give more volume and a deeper location for a lead keel. Hopefully this will solve the stability problem. Bob
