🔍 Key Concepts

• 46 CFR Subchapter W – Lifesaving/Navigation and related voyage preparation requirements • Difference between what is good seamanship vs. what is explicitly required by regulation before entering U.S. waters • Which items in the options are required on a specific schedule or timing (e.g., within a certain number of hours)

💭 Think About

• Look at each choice and ask: Is this something I must do by law immediately before or prior to entering U.S. waters, or is it just a general good practice? • Decide which option has a clear regulatory timing requirement attached to it (for example, "no more than X hours before" a certain event). • Think about which of these actions would most directly affect immediate safety of navigation at the moment you are about to enter confined or coastal waters.

✅ Before You Answer

• Verify which action is tied to a specific time window before entering U.S. waters in 46 CFR. • Check which options are ongoing requirements (must always be maintained) versus those that must be done shortly before arrival. • Confirm which option relates to testing critical control systems used to keep the vessel on course and under command.
