ABSTRACT:
A shock mitigation system for a hydrofoil marine craft is provided, the shock mitigation system includes a pair of stacked lifting bodies, where an upper lifting body is used to provide initial lift for the craft. To mitigate the wave effects on the craft when operating at cruise speed, the distance between the upper lifting bodies and the waterline is proportionally related to the operational wave height. When operated within the selected operational parameters, the distance between the upper lifting bodies and waterline prevents the upper lifting bodies from becoming wetted and producing sudden increases in lift from wave impact.
