What age children must wear a USCG-approved PFD while underway on the open deck of a recreational vessel under 21 feet in Maryland?

In Maryland, children under the age of 13 must wear a U.S. Coast Guard-approved personal flotation device (PFD) while underway on the open deck of a recreational vessel that is less than 21 feet in length. This requirement applies when the vessel is moving and ensures the safety of young passengers. Parents and guardians are responsible for ensuring that children comply with this law.
