What regulation requires that boating safety equipment be maintained in working order?

The regulation that requires boating safety equipment to be maintained in working order is primarily governed by the U.S. Coast Guard's federal boating regulations, specifically 33 CFR Part 175. These regulations mandate that vessels carry specific safety equipment, such as life jackets and fire extinguishers, and that this equipment be in good working condition. Additionally, state laws may have their own requirements that align with or expand upon federal regulations. Ensuring that safety equipment is functional is crucial for the safety of all aboard.
