For more than two hundred years, Great Lakes shipyards have bolstered America and Canada's commercial and naval power. Vessels like the Edmund Fitzgerald, the Niagara, and Walk-in-the-Water are now the stuff of legend, but lesser-known ships also have their stories to tell. Cargo-carrying schooners, such as Moonlight and Our Son, got faster and bigger over the years, helping them to hold their own against the emerging steamships, while the revolutionary design of the R.J. Hackett set the standard for lake freighters for years. Of course, the Great Lakes have often exacted a heavy toll, as demonstrated by the mysterious disappearance of the Griffon and the harrowing sinking of Pere Marquette 18. Highlighting vessels from the colonial era down to modern times, historian Glenn A. Knoblock explores the maritime heritage of America and Canada.
