OUPV Inland (Six-Pack) Requirements in Maine

Q: Do Maine captains need a state license or a USCG license?

Passenger-for-hire authority is federal. A state may regulate businesses, fishing guides, or local permits, but the captain credential itself is issued by the USCG.

Q: What is the fastest OUPV path?

Start with sea-service letters, the CG-719K medical exam, drug-test compliance, TWIC, CPR/First Aid, and Rules of the Road study. Missing paperwork usually slows the application more than the exam.

Q: Should I choose Inland or Near-Coastal?

Choose Inland for protected or inland waters inside the COLREGs demarcation lines. Choose Near-Coastal when your work requires offshore authority and qualifying ocean or near-coastal sea time.

Maine does not issue this credential. The license is federal, evaluated by the USCG National Maritime Center, and examined through a Regional Examination Center or approved course.

How OUPV Inland sea service is evaluated in Maine

Under 46 CFR 11.467, an OUPV Inland applicant needs 12 months (about 360 days) of vessel-operation experience. The inland endorsement covers Maine six-passenger charters on inland waters inside the COLREGs demarcation lines and excludes the Great Lakes and waters more than the near-coastal limit offshore.

Total service

360 days (12 months)

Recency

90 days within 3 years

Route limit

Inside demarcation lines

What counts as a day

Under 46 CFR 11.211 a creditable day is generally 8 hours of watchstanding or day-working. Great Lakes service counts day-for-day; inland-waters service outside the Great Lakes is creditable day-for-day for up to 50% of the total requirement, and towing or ATB/ITB service counts on a two-for-one basis up to 50%.

Recency rule

46 CFR 11.201(c) requires at least 3 months (90 days) of the qualifying service to fall within the 3 years immediately before you apply, so older sea time alone will not satisfy the NMC evaluator.

Local operating context

Maine's charter fleet runs heavy on lobster-day and tour boats; OUPV Near-Coastal is standard. Some Bar Harbor operations pursue Master 100 for the larger windjammers and overnight charters. 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.
