50 ton captain license requirements in New Hampshire

New Hampshire Master 50 GT candidates usually pursue inspected-vessel authority without needing the full 100 GT ceiling.

How the 50 ton limit is assigned in New Hampshire

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.

Great Lakes/Inland
360 service days
Near Coastal
720 service days
Tonnage limit
17+ or 26+ GRT history

Route baseline

Great Lakes/Inland uses a 360-day baseline, while Near-Coastal uses 720 deck-department days on ocean, near-coastal, or Great Lakes waters, with up to 360 inland-water days allowed as substitute service.

50 GRT tonnage evidence

The current NMC checklists show 50 GRT supported by service on 17+ or 26+ GRT vessels, with the day threshold depending on route. If the documented vessels are smaller, the NMC can issue 25 GT instead.

50 ton Master evidence checklist for New Hampshire

  • Pick the route before counting days: For Portsmouth and Hampton Beach, most inspected charter applicants should test whether their work needs the Near-Coastal route first. Near-Coastal Master less than 100 GRT uses 720 deck-department days, while Great Lakes/Inland uses a 360-day baseline.
  • Prove the 50 GRT limit: The NMC checklists tie 50 GRT to documented vessel size. Near-Coastal can use 180 days on vessels of 26 GRT or above, or 360 days on vessels of 17 GRT or above. Great Lakes/Inland can use 90 days on 26+ GRT vessels, or 180 days on 17+ GRT vessels.
  • Avoid a 25 GT downgrade: If the service days support a Master endorsement but the vessel letters do not clear the 17/26 GRT thresholds, the evaluator can still issue a 25 GT limit. Check the tonnage on each sea-service letter before choosing a course, exam route, or upgrade plan.

Local operating context

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.

Questions candidates ask before applying

What are the 50 ton captain license requirements in New Hampshire?

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.

How much sea time does Master 50 require?

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.

What vessel size history supports Master 50?

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.
