The effectiveness of layers of elastomeric materials bonded to the undersurface of rigid plates in cushioning their impact on calm water was investigated under two-dimensional conditions. It was shown that an elastomeric layer of optimal modulus of elasticity could significantly reduce the slamming forces on flat bottoms falling vertically on a water surface. An elastomeric layer tended to increase the slamming force on wedge-shaped bottoms, but the magnitudes of maximum impact forces on wedge-shaped bottoms either with or without an elastomeric layer were considerably smaller than those values for the flat bottom under identical drop conditions and diminished sharply with increasing deadrise angle.
