Bypassing physical tank tests can result in catastrophic operational failures, as observed when container ships encounter extreme side-to-side parametric roll. When specific wave frequencies match a hull's natural roll cycle, the motion rapidly intensifies, snapping steel lashings and throwing millions of dollars in cargo overboard.
Physical scale testing also proved vital for the Navy's advanced Zumwalt-class destroyer, flagging critical stability risks caused by its inward-sloping tumblehome hull. While the warship later validated its design during rough-weather sea trials, the early prototype models provided essential data on unpredictable behaviors in following seas.
