This study was motivated by the desire to rapidly identify Types Alpha, Bravo, and Charlie slam events as defined in Riley, et al., (2010a), in an automated manner. Riley, et al. observed particular characteristics of vertical acceleration in the wave slam response of high-speed craft. These characteristic acceleration responses were identified as Alpha, Bravo, and Charlie based on free fall acceleration and longitudinal acceleration peaks as described in (2010a). A numerical code was developed to identify Alpha, Bravo, and Charlie events by searching for free fall occurrences and longitudinal acceleration peaks during a slam event. The specific procedure is as follows; note steps 1-5 follow the “Standard g” approach (Riley, et al, 2010b):.
