An influence of the three different ways of implementation ship's block coefficient δ (three geometrical models) on the stresses due to wave bending moment have been investigated. Two models have been applied and compared: beam one (description of the shape usingparameters) and FEM shell model (direct representation of the shape). The outcomes have been compared to Polish Register of Shipping (PRS) rules. The results show that the descriptions of wave bending moments and wave shear forces under the provisions of PRS rules are insufficient, because they do not take into account the impact of the distribution of buoyancy forces on hull stresses. Classification rules requires block coefficient δ in their formulas, but say nothing about ship's hull shape.
