True or False: ABYC and USCG do not require double hose clamps on thru-hull fittings, but ISO "CE" standards do.

The statement is true because the American Boat and Yacht Council (ABYC) and the United States Coast Guard (USCG) do not mandate the use of double hose clamps specifically for thru-hull fittings in their standards and regulations. The requirements set by ABYC and USCG focus on safety and performance but do not stipulate the necessity of double clamps. In contrast, the International Organization for Standardization (ISO) "CE" standards do impose more stringent requirements, including the use of double hose clamps for better reliability and safety in securing the hoses to the thru-hull fittings. This difference in regulations highlights varying levels of safety practices across different standards and organizations, underscoring the importance of adhering to international best practices, especially when it comes to critical components like thru-hull fittings in marine applications.
