Know Your Ships

Besides the essential stats (owner, year built, length, capacity and former names) for hundreds of freighters, tugs, barges, Coast Guard cutters, cruise ships, and saltwater visitors, Know Your Ships also contains essentials about the cargoes the big boats carry,where they load and unload, the locks, canals and waterways they transit, what the boat whistles mean, stack markings and nation flags, plus ways to follow the freighters as they make their way from port to port. In addition, there's a section on Great Lakes marine museums as well as a new Spotlight section that includes stories about ships, sailors and maritime adventures.
