What are the USCG Requirements for the 100 GT Masters Upgrade?

There are three different Master Upgrade Licenses for which a mariner may qualify. Both the amount of sea service time and the sizes of the vessels you have been on will influence the license you are eligible to be issued.

Master Upgrades are tonnage-rated at 25 GT, 50 GT, or 100 GT. The tonnage you are awarded is determined by the size vessels you've gained experience on in your lifetime, as limited by the size of vessels with experience on in the last three years. Time served in obtaining your OUPV License may be applied to the requirements for the Master Upgrade requirements.
