Welcome Aboard

You've arrived at the digital home port of Marine Publishing Co.'s annual field guide Know Your Ships: Guide to Boats & Boatwatching on the Great Lakes & St. Lawrence Seaway, marking its 59th year in 2018.

Meant not only for those with a casual interest in the parade of nautical commerce that passes our shores, Know Your Ships also has plenty to interest the more serious-minded individuals who have a passion for the ships that ply the inland seas.


We are now taking pre-orders for the 2018 edition of Know Your Ships. Pre-orders will be filled directly from the printer which means you will get your copy before it is availble in any store and maybe even before the offical realease date!

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.
