Use the New Hampshire overview to choose between OUPV, Master 25, Master 50, and Master 100 before narrowing this credential checklist.

New Hampshire Master 50 GT candidates usually pursue inspected-vessel authority without needing the full 100 GT ceiling. The practical check is whether your sea-service letters show both the required Master-level days and vessel tonnage that supports a 50 GT limitation for work around Portsmouth, Hampton Beach, Lake Winnipesaukee.
A New Hampshire Master 50 GT application uses the same Master less-than-100 framework as Master 100, but the vessel-size history lands in the 50 GRT band. The route drives the sea-time baseline; the tonnage evidence decides the limit printed on the credential.
New Hampshire's narrow coastline and Lake Winnipesaukee tour-boat scene supports OUPV Inland and OUPV Near-Coastal. 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 50 GT in New Hampshire 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 New Hampshire as it is nationwide. For the full original-application checklist, start with how to get a captain’s license.
The credential is federal. A Master 50 GT applicant documents the Master less-than-100 route service, passes the required Master exam modules, clears medical/drug/TWIC screening, and shows vessel-tonnage evidence that supports the 50 GRT limit rather than a 25 GT limit.
Near-Coastal Master less than 100 GRT uses 720 deck-department days, with limited inland-water substitution. Great Lakes/Inland uses a 360-day baseline. The route and the vessel tonnage evidence are evaluated separately.
The NMC checklists show a 50 GRT limit from qualifying service on 26+ GRT or 17+ GRT vessels, with the exact day threshold depending on whether the requested route is Near-Coastal or Great Lakes/Inland.
