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. Each instructor is a USCG Licensed Master that has gone through a rigorous approval process meeting the standards of the United States Coast Guard to become a certified instructor. They bring a level of knowledge, experience, and professionalism that adds to the total learning process. In the rare event than an online instructor cannot answer your question, toll free telephone support with one of our Staff Instructors will be provided.
The USCG Master License allows the holder to operate inspected vessels as well as uninspected vessels. Any vessel that is certified (authorized) by the USCG to carry more than 6 paying passengers plus crew must have a Boat Captain who holds a 25/50/100 Ton Master license. Ferry boats, harbor tours boats, whale watch boats are examples of inspected vessels.
There are 4 different Master Licenses a mariner may qualify for such as the Master Inland or Master Near Coastal. Both the amount of sea service time and the size vessels you have been on will influence the license you are eligible for. Master licenses are tonnage rated at 25 GT (gross tons), 50 GT, or 100 GT.
The tonnage you are awarded is determined by the size vessels you've gained experience on in the last 3 years - it's called "recency experience." You are not required to advance through the different licenses one at a time. If you meet the USCG requirements for the master 100GT Near Coastal, you'll get that license as your first license. The 4 types of up to 100GT Master licenses are listed below along with the requirements:
Master Inland: 360 days underway experience since age 15; 90 of those 360 days in the last 3 years. Completion of approved Course and Test.
Master Inland/OUPV: 360 days underway experience since age 15; 90 of those 360 days in the last 3 years; 90 of those 360 days outside the boundary lines. Completion of the Mariners Learning System™ Coast Guard approved Course.
Master Inland/Mate N.C.: 360 days underway experience since age 15; 90 days of those 360 days in the last 3 years; 180 of those 360 days outside the boundary lines. Completion of the Mariners Learning System™ Coast Guard approved Course.
Master Near Coastal: 720 days underway experience since age 15; 90 of those 720 days in the last 3 years; 360 of those 720 days outside the boundary lines. Completion of the Mariners Learning System™ Coast Guard approved Course.
