You are signing on a crew. Which person is...

🔍 Key Concepts

• Merchant Mariner’s Document (MMD) endorsement structure for unlicensed ratings • Difference between rating categories (deck, engine, steward’s departments) and specific job titles on board • How certain officer-type positions (like Purser) are credentialed (certificate of registry vs. rating endorsement)

💭 Think About

• Look at which choices are endorsed by a department/rating and which are endorsed only by a job title • Ask yourself: does the Coast Guard normally endorse MMDs with broad department language (e.g., ‘deck department’, ‘steward’s dept.’) or with a single shipboard job title? • Consider how a Purser is usually documented compared with other unlicensed ratings—would you expect to see the work authority on the MMD itself or on another document?

✅ Before You Answer

• Verify which options show a department/rating-type endorsement versus only a specific job title (like ‘Bosun’). • Check whether a Purser’s authority would typically be shown directly as an endorsement on the MMD or by a reference like ‘See certificate of registry’. • Ask: which endorsement format looks least like a standard Coast Guard rating endorsement you’ve seen in the CFR tables for unlicensed ratings?
