This report presents recommended metrics for evaluating the mitigation characteristics of marine shock isolation seats. A mitigation ratio based on shock response spectra is introduced. Acceleration data recorded during seakeeping trials of a high-speed craft are used to compare mitigation ratios of shock response spectra with ratios based only on peak accelerations. The recommended computational approach applies to evaluating seat isolation effectiveness using either high-speed craft seakeeping data or laboratory test data.
