🔍 Key Concepts

• 46 CFR Subchapter T requirements for small passenger vessels • Material properties under fire and impact loads for through-hull fittings • Difference between brittle and ductile materials in critical seawater and hull penetrations

💭 Think About

• Which material in the list is most likely to fail suddenly and crack rather than bend under stress, impact, or rapid temperature change? • For a hole through the hull below the waterline, would regulations favor a material that is tough and ductile, or one that is hard but brittle? • Think about which materials are specifically discouraged or prohibited by Coast Guard rules for critical seawater/hull penetrations on inspected small passenger vessels.

✅ Before You Answer

• Check which material is known to be brittle and can fracture without much warning • Confirm which materials the Coast Guard considers acceptable for sea connections (e.g., bronze, steel of proper grade) • Verify in 46 CFR that the prohibited material is associated with through-hull fittings and sea connections, not just any piping use
