Master 25/50/100 Ton Captain's License

The US Coast Guard Master 100 Gross Tons license allows the holder to act as an operator of any vessel up to 100 Gross Tons (GT) regardless of whether or not it is inspected or uninspected. An example of an inspected boat that would require the operator to hold a master's license could be; a high speed ferry, a whale watch boat, or a charter boat certified to carry more than six passengers. Students successfully completing the Confident Captain/Ocean Pros Master 100 GT course will satisfy the educational requirements necessary to obtain a Master's license up to 100 GT. The tonnage of the master's license that you are actually issued by the US Coast Guard could range from 25-100 GT depending on the tonnage of the vessels on which you have experience.

The Confident Captain/Ocean Pros Master 100 GT curriculum calls for 80 hours of classroom training, as required by the US Coast Guard, in lieu of the Coast Guard exam. Upon successful completion of the Ocean Pros Master 100 GT course and in-house examination, a course completion certificate will be issued to the student. The student can then use that certificate to obtain his/her Master 100 GT license from the US Coast Guard. No testing with the US Coast Guard will be necessary.
