Minnesota Captain's License Requirements (2026)

What a “Minnesota captain's license” actually means#

It isn't a state license — it's the same federal USCG Merchant Mariner Credential with an OUPV or Master endorsement, used nationwide.

Credential issuer

Local route clue

Six-passenger operators on the Great Lakes around Lake Superior (Duluth) need the Great Lakes and Inland OUPV route (or a qualifying Near-Coastal endorsement), then compare Master 50/100 for larger inspected boats.

Which Rules of the Road apply on Minnesota water#

Minnesota holds both inland regimes at their extremes — Lake Superior at Duluth is Great Lakes water under 33 CFR 83.03(q), and the Mississippi headwaters below Minneapolis are Western Rivers under 83.03(n) — with no Part 80 line anywhere in the state. Lake of the Woods and the Boundary Waters raise a separate question, because 83.01(a) extends the Inland Rules to United States vessels on Canadian waters only for the GREAT LAKES, and says nothing about other border water; that is an OCMI question rather than an assumption to carry over. Mille Lacs is an ordinary inland lake. For a Duluth operator the practical item is 46 CFR 11.467(b), which excludes the Great Lakes from a plain inland OUPV endorsement.

33 CFR Part 80 draws no demarcation line in Minnesota. Its 106 sections cover the Atlantic, Gulf and Pacific coasts, Puerto Rico and the Virgin Islands, the Pacific islands and Alaska; a state with no coast has no section, which is itself the answer.

Great Lakes water (Lake Superior) needs no Part 80 line: 33 CFR 83.03(q) defines inland waters to include the waters of the Great Lakes on the United States side of the International Boundary. Under 46 CFR 11.467(b) a plain inland OUPV endorsement covers all inland waters except the Great Lakes.

Western Rivers (the upper Mississippi River) are defined at 33 CFR 83.03(n) and carry Inland Rules provisions the rest of inland water does not: 83.09(a)(ii), 83.14(d), 83.15(b) and the towing-light exception at 83.24(j).

This decides which rulebook you steer by, not where your credential may operate: the route limit is the 46 CFR Part 7 Boundary Line, and the two lines are not drawn in the same place. How the two lines differ · International Rules · Inland Rules

33 CFR Part 80 and the Part 83 definitions above read from eCFR on 12 Aug 2026. Any specific water is a determination for the cognizant Coast Guard Officer in Charge, Marine Inspection.

Credentials charter captains pursue in Minnesota

• OUPV Great Lakes & Inland (Six-Pack) — authorizes six-passenger work on the Great Lakes and inland waters after 12 months of service, including at least 3 months operating vessels on Great Lakes waters.
• OUPV Inland (Six-Pack) — operates uninspected <=6-passenger charter boats on inland waters other than the Great Lakes — bays, sounds, inland lakes, and rivers.
• Master 50 GT — mid-tier inspected-vessel master — typical for charter sport-fish operations under 50 gross tons.
