Flotation Aid Type III has buoyancy similar to Type II but lacks which ability?

• A. Righting ability
• B. Buoyancy
• C. Visibility
• D. Durability

Answer: (A)

Buoyancy is not the only factor in flotation devices—the ability to orient a person in the water matters too. Type II near-shore vests are designed to help turn an unconscious wearer face-up, which improves airway clearance in rough or changing conditions. Type III flotation aids, while they provide similar buoyant support and are more comfortable for activities, do not guarantee that righting capability. So, the feature Type III lacks is the ability to turn or keep an unconscious wearer face-up. Visibility and durability aren’t the distinguishing factor here, since those can vary independently and aren’t what sets Type III apart in this context.
