The Upgrade Master 100 Tons to Master 200 Tons Course will satisfy the examination requirements for upgrade of your MMC from Master 100 gross tons to Master or Mate of not more than 200 gross ton Great Lakes, Inland, or Near Coastal. To receive the upgrade from Master 100 Ton to Master 200 Ton you must meet the USCG requirements. The requirements checklist can be found on the National Maritime Center’s website.

As with all our online courses, this is done at your own pace and when it’s most convenient for you. You have up to 4 weeks to complete the course but most of our students complete it in a lot less time.

Course subjects include:

  • Seamanship
  • Safety
  • Navigation General


Once you complete the online course you will have 45 days to complete a proctored USCG Approved final exam at one of our approved locations. Our school is located in California and our testing locations are currently only in Alameda and San Diego, CA. Upon successful completion of this final exam you will receive a course Certificate of Training that is valid for 1 year to be submitted to the USCG.
