Also asked, what is the advantage of a type 4 PFD?The advantage of the Type IV PFD is that since it is not worn like other PFDs, there are no size restrictions. This type of PFD is designed to be stored on the deck for easy deployment should someone fall overboard.Likewise, what is Type 2 life jacket? Type II: Near-shore Vests: Calm inland waters, where a quick rescue is likely, is the intent of these PFDs. They will turn some unconscious wearers to the face-up position but not all of them. Foam Type II’s are ‘bulky’ and not generally comfortable to wear while sailing, but less ‘bulky’ than foam Type I’s. Subsequently, question is, what is a Type 5 PFD? BUOYANCY: AT LEAST 15.5 LBS These PFDs are designed to keep the wearer in a vertical position, but it is the wearers’ responsibility to maneuver themselves into a face-up position. These types of PFDs are the most comfortable to wear, and popular for recreational boating and fishing.What PFD do I need?Most adults in a bathing suit need seven to 12 pounds of extra flotation to keep their head out of the water. The US Coast Guard specifies a minimum of 15-½ pounds flotation in an adult PFD. If you’re a swimmer and comfortable in the water, a jacket with 16-18 pounds of design flotation should be fine for you.
