Web29 apr 2015 · Negative damping can occur when the keel of a vessel is close to the seafloor or when vessels are close to each other. In that cases, the water gets "pushed" against the opposing surfaces. This "spring effect" can be captured as negative damping. So there may be the possibility, that your negative damping is real. Cheers.
