Which type of life jacket is not designed to turn an unconscious person face up?

Type III life jackets are designed specifically for comfort and freedom of movement, making them ideal for activities like recreational boating, fishing, or other water sports. While they provide flotation and are generally suitable for conscious individuals who can tread water and swim, they do not have the features necessary to reliably turn an unconscious person face up in the water. This is a crucial characteristic in life jacket design, as it enhances the chances of survival for someone who is unable to assist themselves.

In contrast, Type I jackets are specifically designed for maximum buoyancy and the capability to turn an unconscious person to a safe position. Type II jackets can also provide some turning ability, though they are less effective than Type I for that purpose. Type V life jackets are specialized jackets that may have varied designs but, depending on their intended use, can also provide adequate buoyancy and turning capability. Understanding the differences among these types is essential for ensuring safety on the water.
