... series. The majority of the mentioned vessels had, or has, some sort of automatic control of the air cushion pressure. An un-stabilized SES Vessel will 'bounce' at its natural spring mass damper frequency, and also can excite its various acoustic modes requiring a Ride Control System (RCS) during transit...

... characteristics of lightweight lifting bodies in water. The results show that the in-water to in-air natural frequency ratios decrease rapidly as the structure becomes lighter, and the natural frequencies become mode and speed dependent due to changes in the fluid added mass, damping, and disturbing force terms...

..., the trends of the fluid damping and stiffness terms were both significantly different, which can lead to very different unsteady fluid loads, as well as different system resonance frequencies and damping characteristics.
