💭 Think About

• Ask yourself: Is the regulation focusing on doors/hatches that must be kept closed in emergencies, or on routes for people to escape? • Consider which exact wording would warn crew about closing a door or hatch, not using it as an exit. • Think about whether the Coast Guard is more likely to require a minimum size for visibility or a maximum size to limit markings.

✅ Before You Answer

• Verify the exact regulatory phrase used in 46 CFR for watertight doors and hatches on small passenger vessels. • Check whether the lettering requirement specifies minimum height ("at least") or maximum height ("not to exceed"). • Confirm that the required wording refers specifically to "watertight door" or "watertight hatch" and an action to take in an emergency.
