What is placed on the underside of an inflatable liferaft to help prevent it from being skidded by the wind or overturned?

Correct Answer: Option D — Ballast bags

Inflatable liferafts utilize water pockets, or ballast bags, suspended underneath the buoyancy chambers. These pockets rapidly fill upon deployment to enhance lateral stability, effectively preventing the liferaft from capsizing in heavy seas or skidding excessively across the water surface under high winds.
