APL C-9-class container ship

The APL C-9 class is a group of three diesel-powered container ships that Avondale Industries built near New Orleans for American President Lines between 1980 and 1983. The ships were the President Washington, the President Lincoln and the President Monroe, and the Maritime Administration listed the design as C9-M-132b, with a deadweight of 32,800 tons. When the keel of the first ship was laid in 1981 the trade press called the three the largest containerships ever built in the United States. Each was to be 860 feet long with a single screw, driven by a slow-speed Allis Chalmers Sulzer 12RND90M diesel engine built in the United States, with a service speed of 25 knots and room for 2,500 twenty-foot containers. The ships later passed to Matson Navigation Company, which operates them as the Manoa, the Mahimahi and the Mokihana.
