What do merchant marines do now?

The Merchant Marine plays a crucial role in the transportation of goods and passengers both domestically and internationally, particularly during peacetime. Their responsibilities extend beyond mere transportation; they are also tasked with the operation and maintenance of a diverse fleet of vessels. This includes deep-sea merchant ships, tugboats, towboats, ferries, dredges, excursion vessels, and charter boats. These vessels navigate various waterways, including oceans, the Great Lakes, rivers, canals, and harbors. In addition to cargo transport, Merchant Mariners are essential for supporting maritime commerce, ensuring the safe and efficient movement of essential supplies, and providing services that contribute to the economy. Their expertise is vital in maintaining the infrastructure of maritime transport, which is a backbone of global trade and logistics.
