All of them. For every USCG license application you are required to disclose all convictions that were not previously disclosed.

If you plead guilty to or were given one of the following, in any jurisdiction, you have received a conviction.
You need to complete the CG-719C Conviction Statement Form https://media.defense.gov/2018/May/22/2001920378/-1/-1/0/CG_719C.PDF listing everything. You can print off as many pages as you need and make sure to sign them all.
Spoiler alert. The USCG is testing you to see if you're honest. The USCG is looking you up in every criminal database you can imagine for your entire life and if they find one of the things above that you did not disclose your chances of getting a USCG license drop dramatically. It's a test. Make sure you pass.
If you want additional help with navigating this process we recommend the professionals at Mariner Help USCG and STCW Merchant Mariner Credentialing, Merchant Marine Licensing and Consulting Services or Diamond Marine Services.
When you got to renew your USCG license you need to complete the CG-719C Conviction Statement if any of the things above happened since your last USCG application. If nothing has changed then you need to provide a signed Conviction Statement Memo that says, "I previously disclosed all answers to the conviction statement on my previous USCG application. I have no updates or changes to report."
