OUPV Upgrade to Master (100 Tons)




What is a Master License?

A Master license allows you to operate inspected vessels Is it time to upgrade your OUPV license to 100 Ton Masters License? A 100 Ton Master license allows you to operate inspected vessels up to 100 gross tons and/or carry more than six passengers-for-hire. Inspected vessels are inspected by the U.S. Coast Guard and are issued a certificate of inspection. Common examples of these vessels are passengers (e.g. ferries), off-shore supply, towing, and sea school vessels. This course allows you to earn up to a 100 Ton Master license. Your sea service determines both the route and tonnage for your license. The routes include Inland, Great Lakes and Near Coastal. The tonnage of the vessel you can operate also depends on size of the vessel you served on. Tonnage ratings include 25, 50, or 100-ton Master captains license. At a minimum, all students will receive a 25 ton Master license.
