SAILING AND ICE BOATING - Wayzata Historical Society:
One of the thrills that has been a permanent attraction of Lake Minnetonka is that of racing through the wind. The sloop Mary Lee was built by Leaman & Johnson in 1878 for Charles M. Hardenbergh. Before center keel sail boats, sandbags were moved around wherever weight was needed so sloops were cheerfully dubbed "sandbaggers." Lake sloops reached a maximum 24 feet long. There were no crew or ballast sailing rules until 1889. A land-lubber could rent the "Sue" from John Keesling at Wayzata, occasionally with mishap.
The spring the Hattie May steam boat began shooting between Excelsior and Wayzata in 35 minutes, Hardenbergh had his 34 acres on Harrington Point cleared. The lakeshore was shared together with J.A., C.H., & L. Christian. Their brother, George Christian, had sold his milling interests to them the year before. The Hattie May blew up later in the summer, but the Hardenbergh-Christian families still own Spirit Island off Harrington Point.
Ice boating followed suit in the winter months. Rivaling the fastest trains, the best were clocked between 80 and 100 m.p.h.
