A deeper comprehension of hydrodynamic slamming, which can be done by studying the wedge water entry problem, serves to ensure better design and operational curves. In this work, two wedge models that are identical, with the exception of different bottom thicknesses, are vertically dropped into calm water. Pressure, full-field out-of-plane deflections, and strains on wedge bottoms, vertical acceleration, and vertical position are measured. Full-field deflections and strains are measured using stereoscopic-digital imagine correlation (S-DIC) and strain gauge. A nondimensional number, R, quantifying the relative stiffness of the structure with respect to the fluid load is revisited (Faltinsen (1999)). An experimental parametric study on the effect of R on the nondimensional hydrodynamic pressure and the maximum strain is presented.
