Online Master Captain’s License Course
Earn a master captain’s license and take unlimited paying passengers, up to 200 miles offshore, on a vessel up to 100 GRT. The Certificate of Inspection (COI) of the vessel you operate determines the number of paying passengers you may take. Your sea service determines whether you earn a 25, 50 or 100 ton Master Captain’s License. The Scope or “Route Endorsement” of your license is based on the geographic location in which you gained your sea service and may be either Inland, Great Lakes & Inland or Near Coastal. A Near Coastal route endorsement allows the holder to operate up to 200 miles offshore and also covers “Subordinate Routes” such as the Great Lakes & Inland.
“Once I signed up with Diamond Marine I did some research on what options I had for training. I looked at in person schools and online training. I also talked to several Captains that are good friends. They all mentioned US Captain’s Training. I have to say it has been a great experience. The courses, content, videos and practice exams are very well done. Very happy with my experience and will highly recommend US Captain’s Training to anyone preparing for the exams. Thanks for all the effort and detail you put into your service!” ~ Kevin M. (Master 100 Course Student)

However, we recommend preparing your application and submitting it as soon as possible. The application evaluation process typically takes 4 to 6 weeks. You do NOT need to include your course completion certificate with your application. If your application is evaluated and approved for issuance, the USCG gives you one year to complete the course!
If you need help putting your application together, we have prepared the following resources:
