The principle of buoyancy, which is used by LifeJackets, states that the weight of an object displaces the same volume of water as its displacement. This means that a person's weight in water generates a buoyancy force equal to the person's weight when in the water.
A LifeJacket, on the other hand, is constructed from a lightweight form that weighs significantly less than the typical human. Wearing a LifeJacket decreases the total weight that must be displaced by the water, allowing the wearer to float more easily than they would without one.
Even in dangerous seas, it is crucial to wear a properly fitting life jacket that will prevent injuries from impacts and keep the wearer as safe as possible until additional help arrives.
