Merchant Mariner Documentation (MMD) - Part 1

This year my classmates in license majors and I started the Merchant Mariner Documentation process. Merchant Mariner Documentation, or MMD, is the Coast Guard’s merchant marine identification and management system, keeping track of all registered merchant mariners in the United States. It is required to have MMD in order to ship on any commercial vessel in the U.S., so we start the process about 15 months prior to shipping commercially.
