The 25/50 or 100-Ton Master Captain's License is the highest level license that you can acquire. This master boat captain's license allows you to operate inspected vessels (7 passengers or more – like a water taxi or dive boat) or uninspected vessels. Depending on your experience, it will be issued as a 25, 50, or 100-ton. The Coast Guard does not require that you advance through the different licenses one at a time. So, if you qualify, you can go straight to a Master's level as your first license!

The Towing Endorsement is required if you will be engaged in towing a disabled vessel for payment, such as the activities of a Sea Tow or TowBoatU.S. operator.

To carry seven or more passengers "under sail" on inspected saling vessels, a Sailing Endorsement is also required.

Additionally, you will receive a Long Island Sound Training Chart and Official Test Packet for your original attempt at the Chart Plotting final exam in an MLS Carrying Kit.

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 3 different Master Licenses a mariner may qualify for such as the Master Inland or Master Near Coastal.

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.
