About this exam
The U.S. Coast Guard Merchant Mariner Credential Deck General Examination is a knowledge test for applicants pursuing a deck officer endorsement on a merchant mariner credential. It is not a competitive hiring exam: the National Maritime Center evaluates an applicant’s eligibility, including documented sea service, and specifies which examination modules are required. The Deck General module assesses practical knowledge used in vessel operations. Military mariners and veterans may apply, but whether military sea time counts depends on the endorsement requirements and the NMC’s review of the applicant’s records.
Deck General review commonly includes vessel construction and stability, deck operations, cargo handling, safety, and pollution prevention. The full exam package for a deck endorsement may also require separate modules such as Rules of the Road, Navigation General, or chart and piloting topics; check the approval to test for your specific requirements. Preparation is more than memorizing definitions: candidates need to understand procedures, apply concepts to operating situations, and read questions carefully. Use current Coast Guard references and focus study time on topics where practice reveals gaps.
How to prepare for the Coast Guard Deck General exam
- Start with your NMC approval to test and the current examination reference materials. Confirm the exact modules and required topics for your endorsement rather than assuming every deck applicant takes the same package.
- Review Deck General subjects systematically, including vessel construction, stability, cargo operations, safety, and pollution prevention. For any separately required navigation modules, study the relevant Rules of the Road, charts and publications, piloting, and compass concepts.
- Use timed multiple-choice practice to build accuracy under exam conditions. After each session, review why an answer is correct, revisit the underlying reference, and keep a short list of recurring errors such as misreading a condition or confusing similar procedures.
