USS Winchester (SP-156) was an armed yacht that served in the United States Navy as a patrol vessel from 1917 to 1919.

In World War II, Renard was requisitioned for use in the Royal Canadian Navy as a patrol vessel, keeping her name.

The ship was propelled by two geared Parsons steam turbines driving two shafts powered by two watertube boilers creating 15,000 horsepower (11,000 kW).

In January 1918, the vessel was reassigned to the 5th Naval District and operated in the Norfolk-Hampton Roads area of Virginia, where she was assigned to special duty with the U.S. Navy Bureau of Construction and Repair to test minesweeping equipment.

Late in December 1918, Winchester deployed to City Island in the Bronx, New York, where she continued her minesweeping testing duties.

On 13 April 1919, she returned to the 5th Naval District, operating out of Yorktown, Virginia, continuing to test minesweeping gear.

After failing to acquire any British vessels at the outset of World War II for auxiliary purposes, the Royal Canadian Navy discreetly searched the American market for suitable ships.

[5] Renard was brought to Halifax, Nova Scotia and commissioned there on 27 May 1940 with the pennant number S13, which was later altered to Z13, keeping her name.

[1][8] The ship remained at Sydney until 1949, when the yacht was converted to a stationary power plant for a mining development near Mabou, Nova Scotia.
