What is the main advantage of a Type IV PFD?

The main advantage of a Type IV Personal Flotation Device (PFD) is that it is designed to be thrown to someone in trouble. This type of PFD, often referred to as a throwable device, is typically a cushion or a life ring that can be easily tossed to a person in the water who is in need of assistance. The quick deployment and ease of throwing make it highly effective for emergency situations where immediate flotation support is necessary.

While Type IV PFDs can be used by people of various ages and do provide buoyancy, their primary purpose is not to be worn like regular life jackets but rather to serve as a rescue aid. This functionality distinguishes them from other types of PFDs, such as those designed for constant wear. Additionally, Type IV PFDs are not typically inflatable, which further highlights their unique role in boating safety compared to other types that may feature manual inflation capabilities.
