Do Sea Days during the license grace period count?

Yes. The Coast Guard looks at Sea Days within the last 5 years based on when the application is submitted.





For example: Let's say you had 355 sea days when your MMC expired, and they all happened in the previous 2 years. During the grace period, (1 year from when your license expired) you spend time on a small boat and acquire 10 more Sea Days. Now when you submit your renewal application, you will have 365 Sea Days in the last five years.


Important Note: Once your MMC reaches the expiration date, you are no longer allowed to work under its endorsements.


Do I need 360 days to renew my MMC license?

No. If you have less than 360 days in the last 5 years, renewing your USCG National endorsements is as simple as an open book take home test for each endorsement!

We have created a post to give more detail if you have under 360 days at the time for renewal.
