More Information

Successful completion of this course will satisfy the examination requirements for upgrade of a merchant mariner endorsement from Master not more than 100 gross registered tons (on self-propelled vessels of less than 100 gross registered tons) Upon Near Coastal, or Great Lakes & Inland, or Inland Waters to Master of self-propelled vessels of less than 200 gross tons Upon Near Coastal, or Great Lakes & Inland, or Inland Waters. The course completion certificate issued upon successful completions of this course is valid for one application which results in the issuance of an endorsement(s) and may not be used for future application transactions.

With this Master license, the scope of your authority as captain increases from a 100-ton level to a Master up to 200 gross tons on "inspected" vessels. This online Master course is an add-on to the Nautical School's 100 GRT course. After you have successfully completed the course, you can either continue and take the 4-hour Commercial Assistance Towing and/or Auxiliary Sail (for sailors) or just apply for your Master 200 GRT license.

NOTE: The sea service requirements for a Master 200 GRT License upgrade is: 200 GRT - 180 days (25%) required on vessels of 101 GRT or above, OR 360 days (50%) required on vessels of 67 GRT or above.

Upon successful completion, a Certificate of Completion/Diploma will be issued that we can submit to the Coast Guard on your behalf along with the rest of your application so that your Master License may be issued.

The tonnage you will receive is determined by your experience.

  • To be a licensed Master, you must be a U.S. citizen of at least 19 years of age.
  • You may self-certify or have someone attest to your time on the water.

The above requirements can be confusing so we invite you to call our friendly staff at the Nautical School at (631) 226-7300 for clarification.
