National Maritime Center

Serving the Merchant Mariner:

We value the mariner, respect their experience, are considerate of their time, want to get it right the first time and protect personal information.  We are listening to mariners' suggestions for improvement, and we will find a way to say yes when legally and reasonably possible.

NMC Authority

The National Maritime Center is granted authority through federal mandates listed in the Code of Federal Regulation (CFR), NVIC, and Coast Guard Policy Letters.  NMC is a headquarters unit under the United States Coast Guard who works under the auspices of the Department of Homeland Security.

Future of NMC

One day mariners should be able to upgrade or renew their credentials on demand from any cyber location in the world, much like you can access your bank account and withdraw cash from an ATM, or pay your taxes on line.  The Merchant Mariner Secure Electronic Application System will allow access to mariner records or applying online from anywhere in the world.
