To upgrade from a Master 25 GRT to a Master 50 GRT you need to have 90 days of service deck service while holding your USCG license as a Master 25 GRT.

How does that work?

As soon as you have 90 Sea Days while holding your Master 25 GRT you are qualified to upgrade your license to a Master 50 GRT per 46 CFR 11.422. (Note: This also means that you can upgrade your 50 Ton USCG license to 100 GRT when you have 90 days of sea service while holding your 50 ton license on any boat on any waters as long as you are helping with the safe navigation of the vessel.

Does the USCG automatically give me an upgrade when I renew?

No. The USCG does not automatically give you an upgrade, you have to ask for it.

Will I get the upgrade filing through MM-SEAS?

Yes. When you file with MM-SEAS, part of our review process is looking for these upgrades and including them in the renewal application.
