What do you need for a Captain's license renewal application?

Renewing your Captain's license involves several steps:

Step 1: Gather Your Sea Service Documents From the Last Five Years

It’s time to gather your Sea Service Letters and let’s fulfill the Sea Service Requirements. Go track down every CG-719S (Small Vessel Sea Service form), Sea Service Letter on Company Letterhead, Certificate of Discharge and Active Duty/ Reserve documents (USCG TOSS, Army TOSS, NOAA TOSS, USCG AOPS) of sea service you have earned.

Once you’ve gathered all of your sea service documents,Start by counting up your sea days in the previous five years of your renewal application date. This number is what will drive Step 2!

If you know that you are not going to have 360 days in the last 5 years or it’s just a pain in the rear to track it all down, don't stress out. You can easily renew without it!

MM-SEAS User Tip: You can add all of your Sea Service documents into the software. The system will calculate everything for you and you will always have a safe place to store your documents.

1.1 Create CG-719S (Small Vessel Sea Service) Forms for Your own Vessels

If you are the owner of a vessel on which you are claiming service, you can easily create and sign perfect CG-719S forms inside of MM-SEAS.

All you need to do is follow the steps and make sure you record every day that you were underway for over four hours on your vessel. MM-SEAS will guide you through creating and signing a perfect small vessel sea service form(CG-719S) that is ready to submit to the USCG with your application.

MM-SEAS User Tip: MM-SEAS gets rid of the typical math errors that happen with CG-719S forms and ensures that all necessary information has been entered onto the form.

1.2 Proof of Ownership if Using Your own Vessel on CG-719S (Small Vessel Sea Service) Form

If you are the owner of a vessel on which you are claiming service, you must submit one of the following proof of ownership documents for that vessel.

Acceptable proof of ownership may include: Title, Registration (state registered vessels), Certificate of Documentation (U.S. Coast Guard registered vessels), Proof of insurance (which clearly identifies the vessel) or a Bill(s) of sale.

MM-SEAS User Tip: Make sure your name is on the proof of ownership and the vessel ID you use on your CG-719S matches your proof of ownership document. If it doesn’t the USCG will not accept any of your sea time for that vessel.

Step 2: Your Sea Days From the Previous Five Years of Your USCG License Renewal Application Date Will Determine if Training or Tests are Required to Renew

Training and tests for renewal all depend on which USCG Licenses you hold and how many sea days you have in the last 5 years.

MM-SEAS User Tip: If you have added all of your Sea Service documents into MM-SEAS software the system will calculate everything for you and let you know what training and tests you need to simply renew your MMC.

2.1 Easily Renew your USCG License Domestic (National) endorsements

Everyone who holds a Merchant Mariner Credential will have a domestic endorsement such as Master, Mate, OUPV, 1AE, Chief Engineer and/or DDE.

You can find these on your MMC booklet below the statement “is entitled under Title 46 (Shipping) U.S. Code to serve in the capacity or capacities specified (National Only), subject to any limitations indicated”.

MM-SEAS User Tip: If you are using MM-SEAS they will be listed under “Domestic Training” on the Renewal Checklist.

2.2 Renewing Domestic (National) USCG License endorsements and you have 360 or more sea days in the previous five years of your renewal request

You do not need to take any license exam for your domestic USCG License renewal.

Just turn in your sea service making sure it’s signed everywhere it needs to be, the math adds up and it’s easy to read for the USCG Evaluators.

MM-SEAS User Tip: Make sure your name is on the proof of ownership and the vessel ID you use on your CG719S matches your proof of ownership document. If it doesn’t the USCG will not accept any of your sea time for that vessel.

2.3 Renewing your Domestic (National) USCG License endorsements if you have less than 360 days in the previous five years of your renewal request

You will need to take an open book take home test.

This will be emailed to you after your application is approved for all domestic licenses that you hold. If you currently possess a Master 200 GRT Near Coastal and an Able Seaman Special, you will take an open book test for each of them. Remember, you have been sailing and got your original domestic license so the open book test should be a breeze!

You may use any reference material to complete the renewal examination. Google, the library, any book, literally any resource. The only rule is that you may receive no help from any other person.

A grade of 90% is required to pass each module of the open book license examination.

For Officer Endorsements, you have a total of 90 days from the date they email the test. You get three attempts (it's an open book so you have to try to fail) and if you don’t pass after your third attempt you pay the $45 examination fee again and you get three more attempts.

For Rating Endorsements, you have 1 year from the date they email the test. You get three attempts (it's an open book so you have to try to fail) and if you don't pass this exam all that happens is that you will be required to reapply and retake the USCG renewal tests.

MM-SEAS User Tip: When you use MM-SEAS to submit your renewal application our USCG licensing specialist takes care of getting you your Open Book Take Home test emailed directly to you.

Skip ahead to Step 3 if you do not hold STCW endorsements, Radar Observer, Tankerman, Master of Towing or Mate (Pilot) of Towing

2.4 STCW, Radar, Master of Towing and Mate (Pilot) of Towing Endorsements Required Verbiage on your Sea Service Documentation

If you also hold any STCW, Radar, Master of Towing and Mate (Pilot) of Towing endorsements your sea service for renew needs to verify to the USCG that your “service includes ongoing participation in training and drills relevant to Basic Training” for STCW as well as Master of Towing and Mate (Pilot) of Towing.

You also need to get credit if you “carried out Bridge Watch duties in a position that routinely uses radar for navigation and collision avoidance purposes” if you hold a Radar Endorsement.

Certificate of Discharge and Active Duty Seatime (TOSS or AOPS)

  • Holds STCW, Master of Towing or Mate (Pilot) of Towing Endorsements: No Action is Needed

  • Holds Radar Observer: Must be serving as a Master, Mate or AB

If you are missing these exact statements on your sea service letter you have two options. Either have the company create a new sea service letter with the right verbiage or you can have them create a separate memo with exact dates listed on your sea service letter that has the correct verbiage.

If you do not have this exact verbiage your sea time is not counted towards renewal of your STCW, Master of Towing, Mate (Pilot) of Towing or Radar Observer endorsements.

CG719S (Small Vessel Sea Service Form)

  • Holds STCW, Master of Towing or Mate (Pilot) of Towing Endorsements: On a separate memo with exact dates listed on CG719S that must state verbarium, “VESSEL NAME is required to conduct regular fire, emergency, and abandon ship drills.

Step 4: You Need a Picture of Your Current MMC and Attachments to Renew Your USCG License

MM-SEAS User Tip: Add your MMC pages by taking a picture with your phone. This skips the photocopier and allows you to create perfect applications from your phone and desktop. MM-SEAS will store your documents, and automatically alert you as your expiration is coming up.

Photocopy all attachments on front and back of what you are renewing. This can be your uncancelled MMD, MMC, license, STCW endorsement, Certificate of Registry (COR), or Document of Continuity.

Step 5: You need a Valid TWIC, Have Recent Evidence of Applying or a TWIC Exemption Memo

MM-SEAS User Tip: MM-SEAS can create a Perfect TWIC Exemption Memos inside of the site for you. One less thing to worry about and you just saved $125.25 but lost out on TSA Precheck!

If you do need a TWIC card for work then you should renew it online.

Document titled 'DRUG TEST RESULTS'.

Step 6: You need Negative Drug Test Documentation to renew your OUPV Six-Pack captain license

MM-SEAS User Tip: Add your Drug Test Paperwork and MM-SEAS will automatically alert you as the 185 days are coming up.

For all renewal applications, you’ll need evidence of having passed a chemical test for dangerous drugs. You may also use a letter from a marine employer attesting to participation in a random drug testing program, or a letter attesting to pre-employment drug test from your employer instead of a drug test. There are a few exceptions to this requirement including increasing in scope, asking for a duplicate, or applying for an STCW only endorsement.

There are three options to meet this requirement, so schedule your drug test accordingly. You only need to fulfill one of the options and it must be dated within 185 of your application being submitted.

  • Option One: Provide the results of a DOT 5 Panel Urine Test for Marijuana, Cocaine, Opiates, Phencyclidine, and Amphetamines. Make your life easier by bringing the CG-719P Periodic Drug Testing Form with you to the clinic with a certified Medical Review Officer (MRO) approved through AAMRO or MROCC. ​​Make sure your test states Negative and is signed by the Medical Review Officer (MRO). The USCG will not accept a Positive Result, a Negative - Dilute or a Drug Test Document that is not Signed by a Medical Review Officer (MRO)

  • Option Two: Provide a letter on marine employer stationary or on command letterhead attesting to participation in random drug testing program. You must include the exact text from the Overview of Drug Test Requirements Option Two on the USCG website in your letter.  Drug testing letters from a Union will not be accepted by the NMC. If you are part of a Drug Testing Consortium they can provide you a Drug Test Letter. You will need to reach out to your Drug Testing Consortium and ask for a Drug Test Letter to use on your upcoming USCG License Application.

  • Option Three: Provide a letter on marine employer stationary attesting to pre-employment drug testing. You must include the exact text from the Overview of Drug Test Requirements Option Three on the USCG website in your letter.

Step 7: The Federal USCG Fees

MM-SEAS User Tip: Pay.gov fees are one of the most common errors made by mariners. Our team calculates and pays the fees perfectly every time which helps create a Perfect application. That’s why we include it in our fee and guarantee they are done right every time!

If MM-SEAS is creating a Perfect MM-SEAS application for you all of your Pay.gov fees are included in the $349 price for a Perfect MM-SEAS application. You are welcome to figure out pay.gov on your own and we drop the MM-SEAS Perfect Application price down to $249 if you paid the right fees. If you paid the wrong amount it will be full price plus any extra fees we have to pay on your behalf!

Add your receipt to MM-SEAS if you want to do it yourself under Renewal Checklist.

This guidance will help calculate your renewal fees and pay for your renewal on Pay.gov. First, you need to use the table as set forth in 46 CFR 10.219 to calculate the appropriate fees for your license renewal.

Next, go to the USCG Merchant Mariner User Fee Payment page on Pay.gov. Scroll down to the bottom of the page and click the “Continue to Form” button. Fill out the form with your personal details. At the bottom of the first section, “Applicant/Mariner Details,” you will need to choose a Regional Exam Center (REC). Choose the REC that is closest to your home address. The “User Fee Information” section will populate as you select your credential category, endorsement, and credential fees. When you are ready, click “Continue” and pay with a credit card. After payment, Pay.gov will automatically email you a receipt. Keep this email receipt and submit it with your renewal request as proof of payment.

Step 8: Fill Out the CG-719B Application Form

MM-SEAS User Tip: We use your MM-SEAS profile to create perfect CG-719B forms and take care of everything behind the scenes for you. We promise that you will always keep all of the endorsements you want to renew.

It’s strongly recommended that you ask for every single endorsement that you want to be renewed. If you do not put it in writing as part of your renewal application, the USCG commonly omits endorsements you previously held and are qualified to renew.

First, fill out the CG-719B form.

Help with Description of Endorsements Desired Box in Section II - We know the Description of Endorsements Desired Box on the form is small and you might not have room to fit all of your requested endorsements with every single endorsement you want upgraded, added or an increase in scope in the box. If you can’t fit everything in the box, attach a memo to the form and outline why you are qualified.

If you are just renewing all of your endorsements the USCG prefers that you write, “Renewal of all current credentials” in the Description of Endorsements Desired Box in Section II. We recommend attaching a memo with all endorsements you want renewed as well.

Step 9: Submit your Application Packet to the Nearest Regional Exam Center (REC)

MM-SEAS User Tip: If you are using MM-SEAS, we can make PERFECT Applications automatically for you, submit them to the National Maritime Center (NMC) and then deal with them in case any issues come up on your behalf. We put everything in the preferred order for the NMC evaluators to make it as easy as possible for your application to be quickly reviewed and approved.

Submit your completed, signed application and documents, with all of the above eight steps documents attached to the nearest USCG Regional Exam Center via email.

All of your documents must be submitted as PDF. You can use electronic signatures as long as they can be verified and your PDF document is not locked afterwards. Your packages of PDF documents cannot be larger than 35MB as the USCG email systems will not accept attachments larger than 35MB. You need to separate all of your documents into 35MB files to submit to the REC.

When you submit your application packet to the REC, make sure to name each attachment and the email subject line the same: Last, First, MMC Reference number, (Original/Renewal/Upgrade) Package

As an example my first attachment and email subject line for an renewal would be: Gilman, Nate, 3473478, Renewal Package

Additional FAQ:

Is there a grace period for USCG license renewal?

Coast Guard licenses, also known as 'credentials,' are valid for five years, with a one-year grace period for renewal without re-testing. In cases where mariners need to extend this grace period, they can apply for a Document of Continuity, which the Coast Guard will issue for free. For more details on the grace period and the renewal process, you can refer to our detailed explanation here.
