For the ONR Environment and Ship Motions Forecasting ESMF Future Naval Capabilities FNC Program, an understanding of the accuracy of linear ship motions prediction methods is of interest. An experiment was performed in the Maneuvering and Seakeeping MASK basin at the Naval Surface Warfare Center, Carderock Division NSWCCD to measure model-scale ship motion and waves, at moderate speeds, of the RV Melville. Comparisons were then made between the model experiment results and linear, frequency-domain predictions using the USN Standard Motions Program SMP95. This report details the comparison between these results and discusses differences observed and provides an assessment of the limitations of linear, frequency-domain prediction methods for the environmental conditions of interest to the ESMF FNC program.
