What You Need to Know Before Starting
A captain's license is issued by the U.S. Coast Guard and lets you operate a vessel for hire — carrying passengers, running a charter, or working commercially on the water. The license you need depends on the size of the boat and how far from shore you operate. Most people start with an Operator of Uninspected Passenger Vessel (OUPV) license, also called a 6-pack license because it covers boats carrying up to six paying passengers. If you want to captain larger vessels or go further offshore, you'll need a Master license instead.
The Coast Guard doesn't run the training itself — you take courses from third-party schools, then sit for the Coast Guard exam. The whole process typically takes two to four months, depending on whether you already have sea time and how quickly you can schedule your test. You'll need to pass a written exam, a physical exam, and a drug test, and you'll need documented sea time on the water before you can sit for the written test.
Key Takeaways
- You must complete sea time on the water — usually 360 hours for a 6-pack license — before you can take the Coast Guard written exam.
- Third-party training schools teach the material and issue a course completion certificate, which you need to bring to the exam.
- The Coast Guard written exam covers navigation, safety, rules of the road, and vessel operation, and you take it at a testing center in your area.
- You'll also need a physical exam from a Coast Guard-approved medical examiner and a passing drug test before your license is issued.
- The entire process from training to license in hand usually takes two to four months, but sea time requirements can extend that if you don't already have hours on the water.
Documenting Your Sea Time on the Water
Before you can sit for the Coast Guard exam, you must log a specific number of hours operating a vessel. For an OUPV (6-pack) license, you need 360 hours of sea time in the past five years. For a Master license, the requirement is higher — 720 hours for near-coastal or 1,460 hours for ocean service. Sea time means you were actively commanding or helping operate the vessel, not just a passenger aboard.
You'll need someone to sign off on your sea time — typically the boat owner or captain you worked under. The Coast Guard provides a Sea Service Record form that your supervisor fills out and signs. You can read this from the Coast Guard's official website or get it from your training school. Keep detailed notes of dates, hours, and the vessel name as you go, because the form needs to match your records. If you're working toward your license while employed on a boat, your employer can sign off on your hours as you accumulate them.
If you don't have 360 hours yet, you can still start training and take the exam once you do. Many people work on charter boats or fishing vessels part-time to build their hours while taking courses. Some training schools offer partnerships with local boat operators who can help you log time.
Choosing and Completing a Training Course
The Coast Guard requires you to complete a OUPV or Master course from an approved training provider before you sit for the exam. These are not Coast Guard courses — they're run by private schools, maritime academies, and some community colleges. The course covers navigation, rules of the road, safety procedures, vessel systems, and emergency response. Most OUPV courses run three to five days in person, though some schools offer online modules combined with in-person sessions.
When you finish the course, the school issues a course completion certificate. This is not your license — it's proof you took the training. You'll bring this certificate to the Coast Guard testing center when you sit for the exam. The certificate is usually valid for two years, so you have time to schedule your test after training.
Training costs vary widely, from around $500 to $1,500 depending on the school and whether the course is online, in-person, or hybrid. Some schools bundle sea time documentation help or study materials into the price. Before you enroll, confirm the school is Coast Guard-approved and ask whether they provide practice exams or study guides — these help significantly on test day.
Taking the Coast Guard Written Exam
The Coast Guard administers the written exam through Pearson VUE testing centers, which are located in most cities. You schedule your exam online through the Coast Guard's National Maritime Center website. The exam for an OUPV license has 80 questions and you have five hours to complete it. You need a score of at least 70 percent to pass.
The exam covers navigation and chart reading, rules of the road (collision avoidance), vessel safety and emergency procedures, and general seamanship. You can bring a calculator and dividers for chart work, but no other materials. Study guides and practice exams are available from your training school or from the Coast Guard's website. Many people take the practice exam multiple times before sitting for the real test.
When you arrive at the testing center, bring your course completion certificate, a government-issued photo ID, and your sea service documentation. The testing center will verify your sea time before you sit down. If you don't pass on your first attempt, you can retake the exam, but you'll pay the testing fee again — usually around $150 to $200.
Getting Your Medical Exam and Drug Test
After you pass the written exam, you need to complete a Coast Guard medical exam with an approved examiner. This is not a full physical — it's a brief evaluation to confirm you don't have conditions that would make you unsafe to operate a vessel. The examiner checks your vision, hearing, and general health, and asks about any medications or medical history. You can find approved examiners through the Coast Guard's website by searching your state.
You'll also need to pass a drug test before your license is issued. This is typically a urine test administered by a certified lab. Your training school or the Coast Guard's website can direct you to a testing facility in your area. The test screens for common drugs and usually costs $30 to $50.
Both the medical exam and drug test are valid for a set period — usually one year — so schedule them after you've passed your written exam. Once you have all three (written exam pass, medical clearance, and drug test result), you submit them to the Coast Guard's National Maritime Center, either by mail or through their online system. Processing typically takes two to four weeks.
Submitting Your process and Receiving Your License
Once you've passed the written exam, completed your medical exam, and passed your drug test, you're ready to submit your official license process to the Coast Guard's National Maritime Center. You can do this online through their website or by mail. The online system is faster — you upload your documents and pay the license fee (around $150 for an OUPV license) in one step.
The Coast Guard will review your process and documents. If everything is in order, they'll issue your license and mail it to you. This processing step usually takes two to four weeks. Your license is valid for five years, after which you'll need to renew it. Renewal requires updating your medical exam and drug test, but you don't have to retake the written exam.
Once your license arrives, you can legally captain a vessel for hire. Keep your license on you whenever you're operating a commercial vessel — the Coast Guard or state water patrol can ask to see it during an inspection.
Frequently Asked Questions
Can I use my sea time from years ago, or does it have to be recent?
Sea time must be within the past five years. Hours you logged more than five years ago don't count toward your requirement. If you're returning to the water after a long break, you'll need to build your hours again before you can sit for the exam.
What if I don't have anyone to sign off on my sea time?
You need documented sea time signed by someone who supervised you on the vessel. If you're building hours now, ask your current employer or boat captain to sign your sea service record as you go. If you worked on a boat years ago and can't reach the owner, contact the Coast Guard's National Maritime Center — they may accept alternative documentation in some cases.
Do I need to take the exam in my home state?
No. You can take the Coast Guard exam at any Pearson VUE testing center in any state. Your license is issued by the federal Coast Guard, not by a state, so it's valid nationwide. Schedule your exam wherever is most convenient for you.
What's the difference between a 6-pack license and a Master license?
A 6-pack (OUPV) license lets you carry up to six paying passengers on vessels under 100 gross tons, usually within 100 miles of shore. A Master license covers larger vessels and longer distances. If you only plan to run small charters, a 6-pack is sufficient and requires fewer sea hours. A Master license is needed for larger commercial operations.
How much does the whole process cost?
Training courses range from $500 to $1,500, the written exam costs $150 to $200, the medical exam is $50 to $150, the drug test is $30 to $50, and the license fee is around $150. Total cost is typically $800 to $2,000, depending on your training choice and location. This doesn't include the cost of building your sea time, which depends on your employment situation.
