Use the Missouri overview to choose between OUPV, Master 25, Master 50, and Master 100 before narrowing this credential checklist. Because the credential is federal, the national Master 25 ton guide carries the full requirement detail — Missouri only changes your nearest REC and local operating context.
Document the sea service required for Master 25 GT, usually 360 days depending on route and tonnage.
Complete the CG-719K physical, drug test, TWIC, CPR, and First Aid requirements.
Study Rules of the Road, Deck General, Deck Safety, and Navigation General. Master candidates also need Plotting and the broader General module.
Schedule the exam at REC St. Louis, MO, or use an approved school that administers the USCG exam.
Missouri Master 25 GT candidates are usually planning small inspected passenger-vessel work. The sea-service package still has to support a Master endorsement, but the tonnage history can be lighter than a 50 or 100 GT application.
For Missouri candidates, Master 25 GT is usually the result when the route service is valid but the vessel-size history does not support a 50 or 100 GRT limit. The application has to show both the route baseline and the tonnage evidence the NMC uses under 46 CFR 11.422.
REC St. Louis is the central inland REC. Lake of the Ozarks and Table Rock Lake guides pursue OUPV Inland. For exam prep, the federal question set does not change by state, but your likely route matters: inland candidates lean harder on Inland Rules and aids to navigation, while near-coastal candidates need COLREGs, navigation, weather, and chart-work discipline.
A Master 25 GT in Missouri is a federal Merchant Mariner Credential endorsement, so the steps after your sea time are the same in every state. First comes the written test — the USCG exam format and module breakdown shows exactly which subjects your route is tested on and the 90% Rules-of-the-Road and Chart-Plot pass marks before you book a Regional Examination Center seat.
Once issued, the credential runs on a five-year cycle under 46 CFR 10.227. When it comes due, the USCG license renewal process — forms, cost, and the medical certificate is identical in Missouri as it is nationwide.

The license is federal. State location affects your nearest REC and operating context, but the sea-time, exam, medical, drug-test, TWIC, and application requirements come from the Coast Guard.
Yes. The Coast Guard uses qualifying vessel tonnage to decide whether the endorsement is issued at the 25, 50, 100, or 200 GRT level.
Master is broader because it can cover inspected passenger vessels. OUPV is still enough for many six-passenger uninspected charters, so the right credential depends on the vessel and passenger count.
