Coast Guard Regulations (46 CFR) require...

🔍 Key Concepts

• 46 CFR requirements for watertight doors on cargo vessels (Subchapter I – Cargo and Miscellaneous Vessels) • Difference between design/installation requirements and testing/inspection requirements • How often critical safety equipment must be demonstrated or tested for the vessel to legally operate

💭 Think About

• Decide which choices describe a permanent design feature of the system, and which describe a recurring test or procedural requirement. • Ask yourself: when does the Coast Guard formally check and document that watertight doors work—during normal voyages, or during official inspections tied to the vessel’s certificate? • Consider whether 46 CFR generally mandates a specific type of power/control for all cargo‑vessel watertight doors, or focuses instead on their proper operation and regular verification.

✅ Before You Answer

• Check in 46 CFR whether cargo vessel watertight doors are required to be a specific power type (electric or hydraulic), or if different arrangements are allowed. • Verify when watertight doors must be operated and demonstrated to the Coast Guard: during inspections for certification vs. within a fixed number of hours after departure. • Confirm that the requirement you choose applies specifically to cargo vessels, not just passenger ships or special‑service vessels.
