The Maritime Association of South Carolina (MASC) has been actively promoting the interests of the Port of Charleston since 1926. Today, it contributes to the growth and success of port-related businesses throughout the state. Once limited to companies engaged in, or providing services to, the maritime trade, membership is now open to a much broader base of businesses, agencies, organizations and individuals.

The waterfront community has a number of highly-regarded professional and trade organizations. MASC, however, is an umbrella association, welcoming participation of other organizations and working for the improvement of our state's ports. We deal with issues both broad and specific in nature.
