Lettens Jan14/01/2012On December 21, 1944, U-806 sank a merchant vessel in the approaches to Halifax harbour. HMCS CLAYOQUOT was searching for this u-boat in company of HMCS TRANSCONA and HMCS KIRKLAND LAKE, when she was struck aft by a torpedo from U-806.

HMCS CLAYOQUOT went down in less than 10 minutes, however 73 of the 81 man crew escaped by life raft and were picked up by HMCS FENNEL shortly thereafter. The exact location of HMCS CLAYOQUOT remained a mystery until 1994 when, what were thought to be her remains were detected by members of the geological survey of canada while field testing side scan sonar equipment.

HMCS CLAYOQUOT was positively identified in september of 1996 when HMCS CORMORANT´s manned submersible dove to the site. On board was retired petty officer Ernie White, a survivor of the sinking, who confirmed the identity of the vessel.

About Builders
 Prince Rupert Drydock & Shipyard
Prince Rupert Dry Dock was primarily a maintenance and repair facility for its owner, initially the Grand Trunk Pacific Railroad, later Canadian National Railway. The shipyard was completed in 1915 when a 20,000-ton floating dock was assembled at the site. The wooden pontoons were built by the general contractor and the steel wing walls were imported and erected at the site. The yard was equipped to build steel vessels but more frequently built wooden boats of various types for the local market. In World War One, it built two good-sized cargo ships and in World War Two, it built four minesweepers and 15 cargo ships. After the Second War the shipyard slowly faded away, the dry-dock finally being sold in 1955 and moved to Seattle. A total of 68 hulls have been identified as being built by them but the hull numbering sequence stopped at 60.
