1977 and cut ties with the company. In June 1984, R.J. Reynolds Industries, Inc. spun off Sea-Land Corporation to shareholders, as an independent, publicly held company, with stock trading on the New York Stock Exchange. Sea-Land achieved the highest revenues and earnings in its 28-year history. In September 1986, Sea-Land Corporation merged with CSA Acquisition Corp., a subsidiary of CSX Corporation. Sea-Land Corporation common stock was exchanged for $28 per share, cash. Sea-Land's international services were sold to Maersk in 1999, and the combined company was named Maersk Sealand, which, in 2006, became known simply as Maersk Line. The former Sea-Land's domestic services was operated until 2015 as Horizon Lines, which accounted for approximately 36% of the total U.S. marine container shipments between the continental U.S. and the markets of Alaska, Hawaii and Puerto Rico, and to Guam. The company was headquartered in Charlotte, North Carolina. In 2015 the company was acquired by Matson Navigation Company. Subsequent business ventures In 1968 McLean financed a real estate project in Waveland, Mississippi that has become Diamondhead, Mississippi. In 1971, the Pinehurst Resort property in Pinehurst, North Carolina was sold to Diamondhead Corporation, a land development company headquartered in a Mountainside, New Jersey and owned by McLean. The venerable old resort which had seen virtually no noticeable changes in its 75 years before its sale became the center of controversy. Finally, in 1982, Pinehurst became the property of Diamondhead's major lenders, who formed a NC corporation called Resort Assets Corporation. With their takeover, a more viable effort was then made to work in concert with Pinehurst village officials to restore the overall community. In 1978, McLean purchased United States Lines. There, he built a fleet of 4,400-TEU container ships that were the largest afloat at the time. The ships, operating in round-the-world service, were designed in the aftermath of the 1970s oil shortages and were fuel-efficient but slow, and therefore not well-adapted to compete in the subsequent period of cheap oil. USL went bankrupt in 1986. McLean took very personally the criticism directed against him after the collapse of USL and the resulting loss of many jobs associated with and dependent on USL. In 1982, McLean made the Forbes 400 Richest Americans list with a net worth of $400 million, however, a few years later, having gambled on rising oil prices that failed to materialize, McLean had to file for Chapter 11 bankruptcy
