The right prescription to "fix" the Tillman Battleship

What is needed to "fix" the Tillman Battleship design in Springsharp 3.0b1 is to increase the beam. That fixes all problems. Of course, it defeats the whole purpose, which was to produce the largest ship that could go through the Panama Canal. The recoil problem seems to be insoluable in Springsharp. This the Springsharp report with those changes:
