🔍 Key Concepts

• 46 CFR Part 10 – Rules about suspension and revocation of merchant mariner credentials • Difference between a license and a passport (travel ID vs. professional credential) • Scope of authority of an engineer’s license versus a master’s license

💭 Think About

• Which option clearly matches something you know the Coast Guard can do if a mariner is found negligent? • Look at each choice and ask: does this describe an engineer’s professional credential, or is it describing either a different document (like a passport) or a different type of license (like master)? • Think about normal renewal cycles for Coast Guard credentials: does 2 years sound right, or is there a more common longer period?

✅ Before You Answer

• Verify in 46 CFR that Coast Guard credentials can be acted on (suspended or revoked) for misconduct or negligence. • Confirm whether any Coast Guard license or MMC can legally substitute for a U.S. Passport for international travel. • Check that an engineer’s license does NOT automatically grant master authority over any tonnage or vessel type unless that authority is specifically endorsed.
