CFAV Lynx (YAG 320)

Canadian Forces Auxiliary Vessel (CFAV) Lynx (YAG 320) was one of ten wooden YAG-300 (Yard Auxiliary, General) vessels built for the Royal Canadian Navy (RCN) between 1953 and 1955. Built for use as auxiliary craft, Lynx primarily served as an at-sea training platform for junior naval officers, boatswains, reserve personnel and Sea Cadets at Canadian Forces Base (CFB) Esquimalt.

Design and layout
Like other YAG 300 vessels, Lynx was 75′ long overall, 18′6″ wide, had a draft of 4′6″, measured 70 tonnes, and was powered by twin 6-71 Detroit Diesel engines. Lynx was arranged in typical naval fashion with officer’s housed forward with the galley and their own head, an engine room midships, and cadet room aft with 12-14 bunks in double tiers. The heads are equipped with a pump-action lever, that can be used to pump sewage into the black water treatment tanks held aboard or into the ocean water. Above decks was the wheelhouse mounted on the forward cabin's coaming; aft of that, the exposed breezeway; and, mounted on the after cabin's coaming, a Zodiac launch as well as a food locker and barbeque. Above the wheelhouse was an open bridge, fitted with a chart table and a gyrocompass repeater. A second gyro repeater was fitted on the quarterdeck. Lynx was equipped with a Furuno 1831 navigation radar, with the display located in the wheelhouse.

Operational history
In 1955 she was built for the RCN as YFM 320 (Yard Ferry, Man) and served as a harbour ferry boat. Re-designated as YFP-320 (Yard Ferry, Personnel) in 1960, she was designated as a tender to HMCS Oriole in 1963. Later designated as YAG 320 Lynx, she was regrouped under the control and operation of the Small Boats Unit (SBU) at HMC Dockyard Esquimalt where she was used for seamanship and navigation training until 2007. Lynx was offered for sale by the Canadian Government as part of the YAG 300 Replacement Project, which saw the YAG boats replaced by new Orca-class patrol vessels. In 2011 she was sold to private owners for $11,378, converted to a private yacht and renamed RNOOKNOO.
