The use of analytical results to characterize the bottom slamming and deck wetness of a United States Coast Guard Medium Endurance Cutter WMEC in head seas is justified on the basis of correlation with a prior experiment and of a hypothesis to the effect that dynamic swell-up and incident wave distortion can be neglected for purposes of computing slamming probabilities. Slamming and deck wetness are then analyzed in the context of the wave environment for two WMEC operational regions. This analysis indicates that the WMEC will be limited by slamming in wave conditions which are expected to occur at least one percent of the time in both regions considered. It also shows that the operation of the ship may be limited by deck wetness at low speeds in rarely-occurring long waves.
