  • Cushions: Cushions are intended to serve as both a flotation device and a boat seat. They are less stable than ring and horseshoe buoys but more comfortable to sit on.


What Is The Main Advantage Of A Type IV PFD?

When it comes to water safety, having the proper equipment may make or break you. A Personal Flotation Device is an essential piece of equipment that every boater should have on board (PFD). While there are various types of PFDs, a Type IV PFD has a distinct advantage that makes it an indispensable tool for any watercraft. This page will explain what a Type IV PFD is, its benefits, and which vessels must have one on board.

What Is a Type IV PFD?

A Type IV personal flotation device (PFD), often known as a throwable device, is a flotation device meant to be thrown to someone in difficulty in the water. It is not designed to be worn, but rather to offer temporary buoyancy until a rescue can be carried out. Type IV PFDs are available in a variety of shapes and sizes, including ring buoys, horseshoe buoys, and cushions. They are built of buoyant materials and are conspicuous in the water, making them easier to find in an emergency.

What Is the Advantage of a PFD?

Personal Flotation Devices (PFDs) have numerous benefits in terms of water safety. They are intended to keep the user floating and keep them from drowning. PFDs also offer thermal protection, which can aid in the prevention of hypothermia in cold water. They come in a variety of shapes and sizes to fit a variety of activities such as boating, fishing, and water sports.

What Vessels Must Have a Type IV PFD?

All recreational boats 16 feet or larger must have at least one Type IV PFD on board, according to the US Coast Guard. This is true for all recreational boats, including canoes, kayaks, and paddleboards. Depending on their size and intended use, commercial vessels such as fishing boats and passenger’s vessels must also have Type IV PFDs on board.


Type IV PFDs provide an important benefit in water safety by offering a solid and secure flotation device that can be thrown to a distressed person. They are simple to use, give buoyancy, are visible in the water, and are reasonably priced.

Ring buoys, horseshoe buoys, and cushions are the three primary varieties of Type IV PFDs. It is critical to note that a Type IV PFD cannot be used in place of other types of PFDs and should be replaced if it shows symptoms of wear or damage.

You can better prepare for an emergency and safeguard the safety of yourself and your passengers if you have a Type IV PFD on board.
