The Green Star Line was a U.S.-based steamship shipping line established in 1919 by Irish business figures, functioning until 1923. It was created as a result of the Shipping Board's campaign to promote American investment in maritime shipping during and following World War I.
Overview
Joseph Mercadante, who also managed the Nafra Steamship Company, led the Green Star Line, originally known as the Green Star Steamship Corporation. The firm initially acquired four steamships from Portland and set its main office in Baltimore. Its operations centered around four primary routes: Baltimore to South America’s River Plate region, Maryland to Bordeaux, Shanghai, and Antwerp/Rotterdam. Other services extended to Hamburg and Bremen, alongside the continued operation of Nafra’s New York-Genoa route.
By October 1921, worries emerged regarding the company's outstanding obligations to the Shipping Board. Green Star had purchased nine vessels from the Board and owned a total fleet of eighteen ships. In February 1923, five vessels were sold at a loss in Baltimore. Subsequently, in March 1923, the company restructured as Planet Steamship Corporation, which took over the remaining ships. Investors were allowed to exchange their Green Star shares for Planet stock.
Background and Nafra Steamship Company
Joseph Mercadante also headed the Nafra Steamship Company, whose branch "Nafra Line" was recognized for proficient ship management. The Nafra Line expanded its fleet by adding vessels such as Tidewater and Plymouth. In October 1919, Nafra transferred its ships to the newly incorporated Green Star Steamship Corporation, capitalized at $10 million, which incorporated ten additional vessels with ambitions to build a fleet of twenty-two ships. Robert McGregor, formerly general manager at Federal Shipbuilding, served as vice-president and general manager.
Another Nafra affiliate, Nafra Stevedoring Company, offered stevedoring services in Baltimore. One notable ship constructed by Northwest Steel in Portland was sold to Green Star prior to its launch and named Centaurus. Finished in December 1919, it held U.S. official number 219283.
- On 18 January 1920, The Sunday Oregonian reported that Green Star had acquired four steel steamers in Portland with plans for five more additions. The company established its Baltimore headquarters for shipping operations. The four vessels—Circlnus, Corvus, Centaurus, and Clauseus—served routes including Australia, Chile, San Francisco, and Hamburg.
- Green Star announced four scheduled services: Baltimore to Río de la Plata; Maryland to Bordeaux; a new Shanghai route; and Antwerp/Rotterdam. Additional lines included Hamburg, Bremen, and Trieste. The New York-Genoa service previously operated by Nafra continued under Green Star’s management.
- Louis F. Swift joined as a director on the company’s board, potentially connecting Chicago’s meatpacking industry interests with Green Star’s maritime business.
- With ownership exceeding twenty American-registered vessels, Mercadante anticipated that Green Star would become the largest American shipowner once its expansion was complete.
- Vice-president Robert McGregor revealed intentions beyond freight transport, including plans to acquire former German passenger liners.
This growth strategy demonstrated a business approach aimed at diversified international operations along vital trade corridors while capitalizing on American registry benefits and targeting substantial shares within transatlantic and Pacific shipping markets.
Debt and Planet Steamship Corporation
- On October 5, 1921, The Milwaukee Journal announced:
Green Star Line Placed Under Receivership
Washington – The designation of a receiver for Green Star Line Steamship, headed by Josoph Mercadante, reflects significant financial difficulties.
Among the creditors were the government alongside roughly 2,000 bondholders across the country. The firm managed eighteen steamers and was among the initial buyers of vessels from the shipping board.
The Emergency Fleet Corporation held a $15 million investment, with nine ships acquired from the shipping board. As of May 31, the company’s debt to the shipping board totaled $5,503,808.03.
In February 1923, five Green Star Line vessels were sold at a Baltimore auction for $735,000—a figure regarded by industry analysts as below market value. The company underwent formal reorganization in March 1923 when "Planet Steamship Corp." purchased the remaining fleet. By September 1923, stock exchanges permitted holders of Green Star Line shares to exchange their investments for those in Planet Steamship Corp. Key ships such as Circinus and Centaurus were transferred to Planet Steamship Corp.
