The objective of the test was to generate a planing hull data set that could be used in the development of Computational Fluid Dynamics (CFD) based design tools for high-speed planing craft. To accomplish this objective, a detailed set of experimental data was obtained on the model in both the fixed trim and free-to-sink-and-trim conditions. The experimental data includes six-component force and moment data with the model fixed in pitch to the carriage over a matrix of different keel lengths, drafts, and pitch angles, through an equivalent full scale speed range of 25-50 knots. The model was run free-to-sink-and-trim to obtain force measurements over a test matrix of varying displacements and longitudinal centers of gravity (LCG), In this condition, the model was tested over a speed range corresponding to 5-50 knots full scale. The fixed and free data was obtained in calm water and regular head-sea waves. Extensive video documentation of the flow around the hull forms was obtained in conjunction with the measurements obtained on the model.
