Introduction: The
National Mariners Association (NMA) is a non-profit mariner membership
organization. You can read about us on
our website, www.nationalmariners.us. Our Association gathered and compiled many
documents to inform and instruct an estimated 126,000 licensed and unlicensed
“limited-tonnage” credentialed merchant mariners. These mariners serve on U.S.-Flag commercial
vessels such as tugs, towboats, offshore supply vessels, small passenger
vessels, and charter boats.
