On Saturday April 19th 2008 Scott Christopher, a Seattle area NAUI Technical Dive Instructor, and “Northwest Grateful Diver” Bob Bailey dove the wreck of the YMS 359. The YMS 359 was a YMS-1 Class Auxiliary Motor Minesweeper : Laid down September 12th, 1942 by Robert Jacob Inc., City Island, NY; Launched April 9th, 1943; Completed August 20th 1943. It was struck from the Naval Register February 7th, 1947. It was then sold January 6th, 1948. The vessel was sunk in the middle of Lake Washington straight out from Carillon Point, Kirkland, WA at a depth of 200 feet.
The ship has the following specifications : Displacement 270 t.; Length 136'; Beam 24' 6"; Draft 8'; Speed 13 kts; Complement 50; Armament one single 3"/50 gun mount; Propulsion two 880 shp General Motors diesel engines, two shafts.
The dive team descended to 190 feet and tied in a primary reel. The ship was located within seconds. The Scott Christopher carefully tied off the primary reel mid-ship and lead the teams exploration toward the bow section. The wreck is in fair condition. There are several side compartments panels that have been removed that will allow easy access for future penetration. This wreck was easy to identify as the military numerical markings are still present on each side of the ship. The Starboard side was explored from mid ship to the bow. The team continued exploration around the bow, surveying the upper portion of the port side of the vessel. The cabin structure is still clearly identifiable.
This wreck is covered with exploration line that was left, either by careless explorers or abandoned due to an emergency that arose. Our dive team operations will plan a future expedition to this site in order to remove this unwanted and potentially deadly hazard. Our goal is to restore this vessel to the original condition in which it sank.
