Chapter 4: The Legal Requirements of Boating
Personal Flotation Devices (Life Jackets)

All vessels must be equipped with U.S. Coast Guard–approved life jackets called personal flotation devices or PFDs. The quantity and type depends on the length of your vessel and the number of people on board and/or being towed. Each PFD must be in good condition, the proper size for the intended wearer, and very importantly, must be readily accessible! Readily accessible means you must be able to put the PFD on in a reasonable amount of time in an emergency (vessel sinking, on fire, etc.). PFDs should not be stowed in plastic bags, in locked or closed compartments or have other gear stowed on top of them.

Vessel operators should ask everyone on their vessel to wear a PFD whenever on the water. PFDs can save lives, but only if they are worn!

PFD Requirements

All vessels 16 ft. in length or longer must carry one wearable U.S. Coast Guard–approved PFD for each person on board or being towed. Vessels less than 16 ft. in length must carry one wearable or one throwable USCG-approved PFD for each person on board or being towed. Under federal law, however, a wearable PFD is required for each person on board regardless of the length of the vessel.
All PFDs must be in good and serviceable condition and readily accessible. The PFDs must be of the proper size for the intended wearer. Sizing for PFDs is based on body weight and chest size.
In addition to the above requirements, vessels 16 ft. in length or longer must have one Type IV U.S. Coast Guard–approved PFD on board and readily accessible.
Children under 7 years of age must wear a Type I, II, III or V U.S. Coast Guard–approved PFD at all times while on board any watercraft unless the child is confined in a totally enclosed area of the vessel, such as the cabin area of a houseboat or day-cruiser.
Everyone on board a PWC must wear a Type I, II, III or V U.S. Coast Guard–approved PFD.
PFDs may not be stowed in closed or locked compartments.

PFD Descriptions	Illustrations
TYPE I: Offshore Life Jackets These vests are geared for rough or remote waters where rescue may take awhile. They provide the most buoyancy, are excellent for flotation, and will turn most unconscious persons face up in the water.
TYPE II: Near-Shore Vests These vests are good for calm waters when quick assistance or rescue is likely. Type II vests will turn some unconscious wearers face up in the water, but the turning is not as pronounced as with a Type I.
TYPE III: Flotation Aids These vests or full-sleeved jackets are good for calm waters when quick assistance or rescue is likely. They are not recommended for rough waters since they will not turn most unconscious persons face up. Type III PFDs are used for water sports such as water-skiing. Some Type III PFDs are designed to inflate when you enter the water.
TYPE IV: Throwable Devices/Not Wearable These cushions and ring buoys are designed to be thrown to someone in trouble. Since a Type IV PFD is not designed to be worn, it is neither for rough waters nor for persons who are unable to hold onto it.
TYPE V: Special-Use Devices These vests, deck suits, hybrid PFDs, and others are designed for specific activities such as windsurfing, kayaking, or water-skiing. Some Type V PFDs are designed to inflate when you enter the water. To be acceptable, Type V PFDs must be worn and used in accordance with their label.
