- Finding
- A NARA-custodied photograph documents this hull physically present in the war zone: 'Kerama Retto, Okinawa anchorage. Alongside Monadnock (CM 9) between 26 April and 3 May 1945' - from the USS Isherwood (DD-520) damage-photo series in National Archives group 19GC-c-dd520. A second caption places YMS-183 alongside an unidentified tender in company with sisters YMS-271 and YMS-94. The Kerama Retto anchorage was the Okinawa campaign's forward operating/staging base - the photo window sits inside the Task Group 51.15 report period (2 April - 22 May 1945) and the P34-1 'Assault and occupation of Okinawa Gunto' campaign window (2 April - 30 June 1945).

The Okinawa attribution is consistent with the NARA photograph at Kerama Retto and the TG 51.15 war-diary association; the Fukuoka attribution is consistent with the COMINTRON 101 (November 1945) war-diary association.

- A published book-length biography of this specific hull exists: per the publisher's description it is 'a detailed recount of the daily activities on board the YMS 183 during World War II in the Pacific' in which 'the actual ship log has been used along with the recollections of the remaining crew,' taking the ship 'from its original construction site to its final resting place.' A researcher quoting the book (Ships Nostalgia BYMS history thread) describes its reproduction of the daily log from January 1943 through May 1946, including the ship's post-commissioning passage from the builder's yard to the New York Navy Yard, fitting-out at Marine Basin, Gravesend Bay, magnetic-cable loading, and degaussing-terminal calibration - consistent with the war-diary record of an East Coast work-up followed by Panama/Pacific transit.

- Class context: the YMS type was a 136-foot wooden-hulled auxiliary motor minesweeper designed by Henry B. Nevins, Inc. (City Island, NY); 561 were built (481 U.S. YMS plus 80 BYMS for Lend-Lease) across 35 yacht yards - 12 on the East Coast, 19 on the West Coast, four on the Great Lakes. YMS-1 through -134 carried two stacks; YMS-135 through -445, -480, and -481 carried one; YMS-446 through -479 carried none - YMS-183 is a second-series single-stack boat. Class specs: 136' x 24'6", 320 tons, designed complement 33, one 3"/50 DP mount plus two 20mm, GM 8-268A diesels on two shafts, 880 shp, designed speed 12 knots. Originally rated as service craft for inshore sweeping ahead of amphibious assaults; surviving YMSs were reclassified AMS with names in 1947 - a program this hull never entered, being stricken as YMS-183 on 10 June 1947.

- Finding
- A diesel-driven wooden minesweeper completed in January 1943 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel yard craft of this period were engine exhaust and muffler lagging, compressed-asbestos sheet gaskets, valve and machinery packing, electrical insulation, brake linings, and insulation board in machinery and accommodation spaces. As a diesel vessel she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply; the wooden hull reduces but does not eliminate the era application set (machinery, exhaust, joiner/insulation, electrical).
