Yaw response of landing craft transiting the surf zone is a significant concern for U.S. military forces engaged in amphibious landing operations. However, this subject is not well understood and few investigations have been dedicated to its study. The present investigation used laboratory conditions to investigate and determine variables important to the yaw response of shallow-hulled landing craft. Using a sloped wave basin outfitted with wave gauges and a motion capture system, a unique dataset was obtained regarding the six degree of freedom motion of the landing craft model under a variety of wave conditions. The dataset was analyzed with both linear and nonlinear data analysis techniques. The results of these analyses illustrated variables significantly impacting shallow-hulled landing craft yaw response and were used to develop a statistical representation of landing craft utility (LCU) yaw response.
