- Finding
- Documented for this hull: laid down 21 May 1941 by Frank L. Sample, Jr., Boothbay Harbor, ME; launched 19 April 1942; completed 18 August 1942; transferred to the War Shipping Administration in April 1947; struck from the Naval Register 10 June 1947; fate unknown. Call sign Nan-Able-Love-How. Specifications: 270 t.; length 136'; beam 24'6"; draft 8'; speed 15 kts.; complement 32; one 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; two 880bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts. Page states no DANFS history exists for YMS-106. Sole surviving-image record is a photo from the collection of crew member Joseph Gray, QM3c, whose visible ribbons include the European-African-Middle Eastern Campaign Medal.

- Sample yard construction trades (1941-42); crew (1942-46)
- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track Navy records but shipbuilding lists conflict on the stricken year (1946 vs 1947; see gaps). Contains no asbestos content. The EAME ribbon is a crew member's personal award and may reflect his service on other vessels - it does not establish this hull's theater of operations.

[3]NARA file unit 'YMS-106, 9/5/42-4/30/46', NAID 193169082, Container Roll 8070 - RG 24 Records of the Bureau of Naval Personnel, series Muster Rolls of U.S. Navy Ships, Stations, and Other Naval Activities (142 digitized images) [other_primary]

- Finding type
- historical_record
- Finding
- The National Archives catalogs a digitized RG 24 muster-roll file unit for this hull spanning 5 September 1942 - 30 April 1946 (142 images, online) - wartime Navy service is documented from three weeks after completion through postwar inactivation-era muster rolls. The batch brief's referenced deck-log window (9/5/1942 - 5/31/1943) sits inside this cataloged range; a distinct deck-log file unit for the hull was not located in catalog searches.

- Limitations
- Establishes wartime Navy service and personnel documentation only; muster rolls contain no asbestos or material content. The cataloged record is muster rolls in the Muster Rolls series - the batch brief's 'deck logs 9/5/1942-5/31/1943' phrasing may describe this holding or a second file unit; a separately titled deck-log unit was not found and individual pages were not transcribed or read.

- Finding type
- historical_record
- Finding
- The NARA catalog's full-text index associates YMS-106 with a coherent U.S. East Coast operational record: Inshore Patrol, 3rd Naval District, Ambrose Section (New York Harbor approaches) in the last quarter of 1942, then First Naval District / Eastern Sea Frontier formations - Narragansett Group (1944) and Northern Group (1944-45) - through the end of the war, with a 1945 Boston Navy Yard shipyard-log association. This places the hull's wartime service on the Atlantic coast of the United States (New York, Narragansett Bay, northern New England stations).

- Limitations
- Archival lead only: the catalog's OCR full-text search associates the hull name with these file units; the individual diary pages naming YMS-106 were not read, so context of each mention (assignment, transit, availability, movement report) is unverified. A July 1942 First Naval District diary also matches - predating her August 1942 completion - likely an assignment-planning or fleet-list mention, unverified. No asbestos content.

- Finding
- A primary personnel record places a named crew member aboard this hull: Bellamy (b. 9 Jul 1915, Scott Co., VA; inducted 3 Mar 1944) lists service stations USNTS Great Lakes; NTS(Elec) St. Louis; USNAB Cherbourg; USS YES-231; USN Frontier Base, Tompkinsville, N.Y.; USS YMS-106; separated honorably at PSC Shelton, VA (~Dec 1945). The record is consistent with the New York-area operating footprint documented in the war-diary index (Tompkinsville Frontier Base, Staten Island, immediately precedes the YMS-106 assignment).

- Vessel-history fact only: establishes one named individual served aboard circa 1944-45. NOT an exposure record - no asbestos claim for Bellamy or any individual. His EAME-qualifying service plausibly attaches to the USNAB Cherbourg assignment, not necessarily this hull. Transcription by LVA volunteers; underlying NAVPERS-553 form is the archival original.

[6]Era inference built on: NavSource specifications (2 x GM 8-268A diesels, reduction gear, 2 shafts); YMS-1 class documented as wooden-hulled auxiliary motor minesweepers built to a common BuShips-type design across 35 yacht yards (secondary literature); GAO HRD-80-2 era finding (ev-07); NARA asbestos research guide archival pathway (ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-driven wooden minesweeper completed in 1942 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).

[7]National Archives, 'Researching Asbestos aboard US Naval Vessel up through 1961' - official research guide to the RG 19 Bureau of Ships records documenting asbestos in U.S. Navy materiel 1941-1961 [other_primary]

- Finding type

- Finding
- NARA's official guide states 'the use of asbestos in U.S. Navy materiel from 1941-1961 is a frequently requested topic' and documents the archival pathway for hull-level determination: RG 19 Bureau of Ships general/confidential/secret correspondence filed by hull designation (this hull: 'YMS106'; class: 'YMS1 Class'; type correspondence as last resort), Ship/General Information Books covering propulsion, auxiliary machinery, piping, ventilation, heating and air-conditioning systems, shipbuilding-yard QM correspondence files, specification files (RG 19 S-18/S-19 series; RG 143 specification indexes), and cartographic engineering drawings (19-Hull, 19-Micro) - i.e., the records by which this hull's material content could be proven exist in undigitized archival series.

- Research-pathway documentation, not a hull record: the guide confirms that asbestos content is an archival research question answerable only via undigitized RG 19/RG 143 records - none of those series were consulted for this hull. Does not establish or negate materials aboard this hull.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming YMS-106 was found in the public sources searched (see search_ledger). The hull's wooden construction and diesel plant bound the plausible era application set to machinery/exhaust lagging, gaskets, packing, electrical insulation, and joiner insulation - no boiler/turbine lagging pathway applies.
