- In addition to the above requirement, vessels 16 feet in length or longer must have one USCG–approved throwable device on board and readily accessible.
- Children under 13 years of age must wear a PFD whenever underway on a vessel less than 26 feet in length.
- Each person on a PWC or sailboard must wear an approved PFD.
- Anyone being towed on water skis or similar devices must wear an approved PFD. Ski belts are not approved PFDs.
