The form of the hull bottom is designed considerably flat for the need of taking the ground. The model test results show that the resistance and propulsion performances of the hull form are satisfactory.

In theoretical analysis, Orthotropic plate theory was used for the hull bottom structure based on the elementary plate theory. The stiffness coefficients were derived.
