This course is for those who wish to upgrade their existing OUPV License (Six-pack) to a 25-ton, 50-ton, or 100-ton Master Captain's License . The Master's License is required to operate an inspected vessel that carries seven or more paying passengers. In order to carry seven or more passengers "under sail," a Sailing Endorsement is also required.
Course Subjects Include:
Fire Prevention and Appliances
Lifesaving and Survival at Sea
This course satisfies the examination requirement for the 25-ton, 50-ton or 100-ton Master License. The tonnage level of a Master's license issued will be based on the size vessel on which you have your sea service experience. Students who successfully complete the course will be awarded a certificate that will be accepted in lieu of the standard Coast Guard examination!
For this license, a day of sea service is defined as at least 4 hours underway on any given calendar day and can be counted back to your 15th birthday. You do not have to know the exact dates - just the number of days each year.
License Operating Area
This license can be issued for the Great Lakes, U.S. Inland Waters or U.S. Near Coastal waters (depending on where you gained your experience).
Included with each Mariners Learning System™ course is 24/7 access to our online instructors.

The 25/50/100 Ton Master Upgrade course provides an opportunity for the holder of an OUPV (Captain's) license to raise their grade to a Master-level license. The 25/50/100 Ton Master Upgrade allows the holder to operate inspected vessels as well as uninspected vessels. The 25/50/100 Ton Master License is required by the USCG for any inspected vessel certified to carry more than six paying passengers. Such vessels would include headboats, assistance towboats, large passenger capacity tour boats, etc.
What are the USCG Requirements for the 100 GT Master Upgrade?
There are three different Master Upgrade Licenses for which a mariner may qualify. Both the amount of sea service time and the sizes of the vessels you have been on will influence the license you are eligible to be issued.
Master Upgrades are tonnage-rated at 25 GT, 50 GT, or 100 GT. The tonnage you are awarded is determined by the size vessels you've gained experience on in your lifetime, as limited by the size of vessels with experience on in the last three years. Time served in obtaining your OUPV License may be applied to the requirements for the Master Upgrade requirements.
