sportsman, and in the 1880s was a champion ice yachter at a time when the Hudson just north of Poughkeepsie and the river's salt front, where it freezes over in cold winters, was the center of the sport in the United States. The boathouse was specially built to accommodate his yacht, the Icicle, now on display at the Franklin D. Roosevelt Presidential Library and Museum, also in Hyde Park. The boathouse's double-pitched roof recalls the gambrel roofs found on many Dutch Colonial homes in the area. Sails were stored in the loft, no longer extant. John Roosevelt's crews would warm up between and after races in the cottage's front room. His nephew Franklin spent much time at Rosedale as a boy, and as a young man competed in ice races himself, storing his own yacht in the boathouse. The estate remained in the Roosevelt family's hands until the mid-1950s, when it was subdivided to create the suburban-style residential neighborhood to the south of River Point Road. The main house, boathouse and cottage are the only remaining buildings from Rosedale.
