What distinguishes a Type II life jacket?

A Type II life jacket, also commonly known as a near-shore buoyancy vest, is designed specifically to provide support for the wearer in the water. One of its key features is that it offers a level of buoyancy that helps to turn some unconscious wearers face up, making it easier for them to breathe and increasing their chances of survival in the water. This design is particularly beneficial in scenarios where individuals may find themselves unconscious or incapacitated, as it provides an added layer of safety.

The other choices do not accurately describe the characteristics of a Type II life jacket. For example, while it can be worn in open water, it is primarily intended for use in near-shore environments. Additionally, it is not a throwable device; those are typically categorized differently, like Type IV personal flotation devices. Lastly, although wearing a life jacket is recommended for safety, Type II jackets do not have a strict requirement for continuous wear; they can be used at designated times while on watercraft.
