What Is the OUPV (6-Pak) License?
The OUPV — Operator of Uninspected Passenger Vessels — is the entry-level USCG commercial captain credential. It authorizes you to be the master of a vessel carrying up to 6 paying passengers for hire. The "6-pak" nickname comes directly from that passenger limit.
This is the license you need to legally run fishing charters, sailing day trips, sunset cruises, kayak tours (if motorized), dive trips, or any commercial passenger operation on a vessel not required to be USCG-inspected. Without it, accepting money to take passengers on the water is a federal violation.
The good news: the OUPV is genuinely achievable for any experienced boater. I'll walk you through exactly what it takes.
Full Requirements List
1. Sea Service: 360 Days, 90 Underway
This is the biggest requirement and the one that takes the most calendar time. You need:
- 360 days of sea service on appropriate waters (the route you're applying for — inland or near coastal)
- At least 90 of those days must be underway (not just at the dock or anchor)
- Sea service can be on any vessel, any size — it doesn't have to be commercial
- At least 90 days must be within the past 3 years (recency requirement)
A "day" of sea service is 4 hours or more on the water. So if you spend an afternoon fishing for 5 hours, that counts as a day. You don't have to be underway all day — just 4 hours on the vessel in the water.
In my experience, this is where most aspiring captains undercount. Go back through your logs, receipts, marina records, and photos. You may have more documented time than you think. If you're a recreational boater who goes out most weekends, you might be closer than you realize.
The USCG will accept a variety of documentation for sea service — see the sea service documentation section below.
2. Age: Must Be at Least 18 Years Old
No exceptions. The OUPV minimum age is 18.
3. Valid USCG-Approved First Aid and CPR/AED Training
You must hold a current (not expired) CPR/AED and First Aid certification from a USCG-approved course. The American Red Cross and American Heart Association courses are universally accepted. Course must be current at the time you apply.
4. Drug Test
A negative drug test from a USCG-approved laboratory is required. Your physician's office typically cannot administer this — it must be a DOT-compliant facility. Test must be current within a year of your application.
5. Physical Examination (CG-719K)
A licensed physician must complete form CG-719K, the USCG Medical Evaluation Report. This is a straightforward physical — vision, hearing, blood pressure, general health. There's no extreme fitness requirement. The form is available on the USCG website.
Key standards to know: correctable vision to 20/40 or better; no untreated medical conditions that would impair your ability to safely operate a vessel. The exam is designed to catch serious conditions, not disqualify healthy people.
6. Transportation Worker Identification Credential (TWIC)
A TWIC card — issued by TSA — is required for access to secured maritime facilities and is part of the licensing process. Apply for this early, as it takes several weeks to process. You apply at a TWIC enrollment center; fees are approximately $125.
7. Fees
The current USCG credential issuance fee is approximately $140 for the initial credential (prices are subject to change; confirm with the NMC or your REC). There may be additional fees for credentials with multiple route endorsements.
8. Background Check
The USCG runs a background check as part of the licensing process. Certain criminal convictions can disqualify you; drug-related offenses are taken particularly seriously. If you have a record, consult the USCG suitability determination guidelines before investing time and money in the exam process.
How to Document Your Sea Service
This is where many applications stall. The USCG is specific about what documentation they accept, and unclear sea service records are the most common reason for application delays.
Acceptable forms of sea service documentation include:
- Vessel operator/owner letter: A signed letter on official letterhead (or with contact information) from the vessel owner or operator, stating your name, the vessel name and official number (if documented), dates of service, and that the time was spent on appropriate waters. This is the most common method.
- Personal logbook: A consistently maintained logbook with dates, vessel names, waters operated on, and hours underway. Must be signed or otherwise verifiable.
- Commercial sea service records: Pay stubs, employment records, or official vessel logs if you worked commercially.
- Military service records: DD-214 and related documentation for sea-based military service.
Start keeping a log now — even retroactively documenting past trips from memory, photos, and marina receipts. Be honest and accurate; fraudulent sea service claims are federal offenses.
The USCG accepts sea service on any type of vessel, any size, including recreational boats. Time on your friend's 22-foot center console counts. Time crewing on a sailing regatta counts. Time spent working on a commercial fishing boat counts.
What the Exam Is Like
The OUPV exam consists of 60 questions across 7 subject areas. You have 70 minutes to complete it. Most testing is done at a USCG Regional Examination Center (REC) near you.
The exam is administered on a computer at the REC. Questions are multiple-choice. You're provided with a calculator, parallel rulers or a plotter, dividers, and relevant nautical charts for the navigation questions. No cell phones, no notes.
The most important thing to know: Rules of the Road requires 90% to pass. All other sections require 70%. Many students are surprised by this when they sit down. Don't be caught off guard.
If you fail a section, you can retake it (there's a waiting period and additional fees). You don't have to retake sections you passed.
The REC Application Process
Here is the step-by-step sequence for submitting your application:
- Gather all documents: Sea service records, CG-719K physical form, CPR/First Aid certificates, drug test results, TWIC card, government-issued photo ID, and completed application forms (CG-719B and CG-719S).
- Apply online through the National Maritime Center (NMC) portal or submit in person at your nearest REC. Online submission is now available for most applications.
- Application review: The NMC reviews your application and notifies you if anything is missing. This can take several weeks.
- Receive exam authorization: Once approved, you'll receive a letter authorizing you to sit for the exam at a designated REC. The authorization is typically valid for 60 days.
- Schedule and take the exam at the REC.
- Receive your credential: If you pass all sections, your credential is mailed to you within a few weeks. You may receive a temporary letter of authority in the meantime.
Timeline: From Start to Finish
The honest timeline for most people is 3 to 6 months from when they start actively working on the application to when they have the credential in hand. Here's what drives the variance:
- Sea service: If you already have 360 documented days, this doesn't slow you down. If you're short, you're waiting for time on the water — the clock is the constraint.
- TWIC card processing: Plan 4-6 weeks minimum. Apply early.
- NMC review: Application review can take 4-8 weeks in the current processing queue.
- Exam scheduling: Depends on your nearest REC's availability.
- Study time: Most students need 6-10 weeks of consistent study to pass all sections, particularly COLREGS.
Start your TWIC and physical simultaneously with your sea service documentation. Don't do these steps sequentially if you can do them in parallel.
Tips From Experience
A few things I wish someone had told me before I started the process:
- Get your sea service documentation organized before anything else. Missing or unclear sea service is the most common source of delays. Don't assume the REC will accept informal records.
- Overdocument rather than underdocument. If you have 400 days of documented sea service, submit it all. The USCG will count what they count. Don't pre-filter your records.
- Study COLREGS first and most. It's the hardest section, has the highest passing threshold, and is the section most students fail. Start there.
- Talk to a licensed captain. If you know someone with the credential, ask them to walk you through their application process. The written guides help, but firsthand experience is invaluable.
- Use the USCG's own resources. The National Maritime Center website has official guides, application forms, and checklists. Use them alongside study materials.
The Exam Checklist
When your exam day comes, bring:
- Government-issued photo ID
- Your exam authorization letter from the NMC
- Nothing else (the REC provides all navigation tools)
Check out the full USCG exam checklist for a complete rundown of application documents, study materials, and what to bring on exam day. With proper preparation, the 6-pak license is well within reach for any experienced boater willing to put in the study time.
