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 56th year in 2015.

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.

Know Your Ships

Besides the essential stats (owner, year built, length, capacity and former names) for hundreds of freighters, tugs, barges, Coast Guard cutters 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 2012 we added a section dedicated to Marine Museums. This year we've added a section on Great Lakes cruising and we profile the new Algoma Central Corp. laker Algoma Equinox by riding along with Capt. Seann O'Donoughue.
