The Mayflower was a wooden hulled scow-schooner that sank on June 2, 1891, in Lake Superior near Duluth, Minnesota, United States, after capsizing with a load of sandstone blocks.

[1] The Mayflower (official number 92025) was built in 1887 in Sturgeon Bay, Wisconsin,[3] by master carpenter Harry Johnson.

[3] On the day of June 2, 1891, the Mayflower was bound for the Duluth, Minnesota, with a cargo of sandstone which was to be used in the construction of the Central High School.

Three of her crew members were saved by the tugboat Cora A. Sheldon, but Captain Zirbest lost his grip on the lifeline that was thrown to him, and drowned.

[5] Today only two partially intact scows are known to exist on Lake Superior: the Mayflower in Minnesota and the Grey Oak in Thunder Bay.
