This report presents empirical equations for estimating curves of constant Asub 1100 and Asub 110 peak acceleration as a function of craft average speed and significant wave height for high-speed planning craft with nominal lengths less than 55 feet. When combined with safety, operational, structural, or propulsion system limit criteria, the equations are useful for creating operational envelopes or safe operating envelopes.
