Ohio Captain's License Requirements (2026)

What a “Ohio 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

USCG National Maritime Center.

Nearest exam route

REC Toledo, OH.

Local route clue

Six-passenger operators on the Great Lakes around Lake Erie (Port Clinton, Sandusky, Marblehead) 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 Ohio water#

Ohio is a two-regime state with the REC in the middle of it. Lake Erie — Port Clinton, Sandusky, Marblehead, Cleveland — is Great Lakes water, inland by definition at 33 CFR 83.03(q) rather than by any Part 80 line, and carrying the 83.23(e) all-round white light option. The Ohio River along the southern border is Western Rivers water under 83.03(n), where 83.24(j)'s towing-light exception applies instead. Rules 9(a)(ii), 14(d) and 15(b) read the same on both. The credential consequence is the one that costs money: 46 CFR 11.467(b) excludes the Great Lakes from a plain inland OUPV endorsement, so the walleye and perch six-pack fleet out of Port Clinton needs the Great Lakes and inland route, and REC Toledo is the office that will say so.

33 CFR Part 80 draws no demarcation line in Ohio. 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 Erie) 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 Ohio 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 Ohio

• 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.
