The Sing Sing Yacht Club lengthened its clubhouse in the 1890s.
Access to the club was by a path from present day North Water
Street (not shown) to a narrow strip of club property south of
the tracks (shown), thence over the tracks on a planked foot-path,
to a foot bridge from shore to the boathouse.
The Sing Sing Electric Light Company established a powerhouse
on Upper Dock. The Ossining Yacht Club built a clubhouse on a
float south of Peter Smith Dock.
