45° 45° Draft Hinge Deep water Shallow water

The Leary Engineering Company  has proposed a ship hull with
hinges that allow it to open into a fl atter shape when entering
shallow water. A simplifi ed version is shown in
Fig. In deep water, the hull cross section would be
triangular, with large draft. In shallow water, the hinges
would open to an angle as high as θ = 45 ° . The dashed line indicates that the bow and stern would be closed. Make a
parametric study of this confi guration for various θ , assuming
a reasonable weight and center of gravity location.
Show how the draft, the metacentric height, and the ship’s
stability vary as the hinges are opened. Comment on the
effectiveness of this concept.
