How do I Increase in Scope from Mate 200 GRT Near Coastal to Master 200 GRT Near Coastal?
Updated: Mar 25, 2022
Because you already hold your Mate 200 GRT Near Coastal under 46 CFR § 11.427. You just need a total of 720 sea days in the deck department, with 360 of them as a Master, Mate or Operator while holding your MMC as a Master, Mate or OUPV and 360 of the sea days must be on Near Coastal or Ocean Waters.
Side note: A lot of USCG approved courses for 100 ton Master also include a 200 ton Mate if you read the fine print. We recommend getting everything you're qualified for all the time so this means if you take a course that has an AND instead of an OR between the USCG licenses you can obtain with the course, get them!

The great part is that you can Increase in Scope from Mate 200 GRT Near Coastal to Master 200 GRT Near Coastal without taking a test or course. All you need is seatime once you hold that Mate 200 GRT Near Coastal no matter what the tonnage limitation is!
What about my tonnage?
To qualify for a 200 ton
If you have 180 days on vessels 101 GRT or larger OR 360 days on vessels 67 GRT or larger you qualify for a 100 ton.
To qualify for a 100 ton
If you have 180 days on vessels 51 GRT or larger OR 360 days on vessels 34 GRT or larger you qualify for a 100 ton.
To qualify for a 50 ton
If you have 180 days on vessels 26 GRT or larger OR 360 days on vessels 17 GRT or larger you qualify for a 50 ton.
I don't qualify for 50, 100 or 200 ton with my current sea time. What do I do?
No worries! Tonnage limitations will apply if you are on smaller boats. This also makes sense as you will probably be working on smaller boats anyway. We recommend not worrying about them and just focus on getting the right type of license for what you currently want to do.
Tonnage limitations are really simple and easy to remove with just 90 sea days once you hold your new MMC! For a mate and a master under 200 GRT all you need is sea time while holding your license to remove them. Here's a blog post that goes into detail.
