Each PFD must be in good condition, readily available and the proper size for the intended wearer. In addition, boats 16 feet in length or longer must carry a Type IV throwable device. In South Carolina, any person under twelve years of age must wear a US Coast Guard approved Type I, II, III, or V PFD when on board a class “A” (less than 16 ft. long) boat.

Additional extinguishers are required in boats larger than 26 ft. Contact the SCDNR for complete regulations.
