In this latest update, Domestic Merchant Mariner Credentials (MMC) and STCW endorsements that expire between March 1, 2020 and December 31, 2020 are extended until the EARLIER of

  • June 30, 2021; OR
  • One (1) year after the initial expiration date of the credential (i.e., one year after the expiration date printed on the credential).

Mariners whose credentials are expiring between now and the end of the year should read the MSIB in full, or contact the Coast Guard directly to understand how it affects their ability to continue sailing.
