When Joseph H. Pyne joined Dixie Carriers in 1978, little did he know the maritime juggernaut he would help to create. When he took over as president in 1984, the company owned about 20 boats and 50 barges, with a value of about $35m. Today, after nearly 30 years, 50 acquisitions, it has a market cap well in excess of $4B, and its fleet hovers around 350 boats and 950 barges, commanding approximately 35% of the U.S. market.
