In this report the data of the tests on scaled fuselages with dynamic pitch performed at CNR-INM (Institute of Marine Engineering), former CNR-INSEAN, on scaled fuselage models are presented. The report provides details on the test models, their design and built, on the experimental setup and the test data. The tests with dynamic pitch enable to estimate the unsteady pressures and loads acting on the fuselage as a consequence of an enforced pitch motion. The data allow to assess the capability of the computational tools to predict the changes in the loading associated with the dynamic pitch variation, which is the forcing terms of the equations of body motion. In turn, this is an important step to ensure an accurate reconstruction of the aircraft dynamics. Moreover, the effect of the interaction with waves during the ditching phase is analysed in both heading and following sea conditions
