Life jacket rules
All vessels must be equipped with USCG-approved personal flotation devices (PFDs), also known as life jackets. The quantity and type depend on the length of your vessel and the number of people on board and/or being towed. Michigan life jacket laws include the following:
- All vessels must be equipped with a PFD for each person on board or being towed.
- A vessel that is less than 16 feet long, or is a canoe or kayak, must have either a wearable PFD (Type I, II, or III) or a throwable PFD (Type IV) for each person on board.
- All children under 6 years of age must wear a USCG-approved Type I or II PFD when riding on the open deck of any vessel while underway.
- The USCG requires that all vessels have at least one Type I, II or III PFD that is USCG-approved, wearable and of the proper size for each person on board or being towed. Sizing for PFDs is based on body weight and chest size.
- In addition to the above requirements, one USCG-approved throwable device must be on board vessels 16 feet or longer and be readily accessible.
- Each person riding on a PWC or being towed behind a PWC or other vessel must wear a USCG-approved Type I, II or III personal flotation device. Inflatable PFDs are not allowed on PWC or while being towed behind PWC or other vessels.
- All PFDs must be in good and serviceable condition and must be readily accessible.
