From 2001 through 2005, containership calls at U.S. ports increased by 9%, but the average size of containerships per call increased by 19%. Also, in 2005, the average size of containerships calling at U.S. ports was 17% larger than for container ships calling at ports around the world. The difference was due largely to a scarcity of U.S. feeder and short-sea services. These services, which use smaller vessels than line-haul services, are common in intra-European and intra-Asian trades.",,,,,,
