Which organization has mandated requirements for electrical systems in boats for propulsion?

The United States Coast Guard (USCG) has the authority to establish and enforce regulations that ensure the safety of vessels and their electrical systems, particularly in relation to propulsion. These regulations are part of the broader framework to ensure that commercial and recreational vessels meet safety standards. The USCG's requirements primarily focus on preventing accidents and ensuring that vessels are equipped with safe and reliable electrical systems for propulsion.

In the context of boating, the requirements set by the USCG can cover aspects such as wiring, circuit protection, and the installation of electrical equipment, all of which are critically important to the safe operation of a boat. This mandate is essential because a failure in the electrical system can lead to catastrophic failures while at sea.

Other organizations, like the National Marine Manufacturers Association and the American Boat and Yacht Council, also play vital roles in the maritime industry, but their focus is often on best practices, guidelines, and standards rather than regulatory enforcement. The Environmental Protection Agency has a different focus, dealing more with environmental regulations rather than specific safety standards for boat propulsion systems.
