[2]DANFS, Konoka (YT-151) - namesake (a village in Seneca County, N.Y.), builder, in-service date, 3d Naval District service, reclassifications (verbatim transcription; no live NHHC page located - history.navy.mil danfs/k/konoka.html and danfs/k/kanaka.html both return 404) [nhhc_danfs]

- Documented for this hull: built 1940 to 1941 by the Defoe Shipbuilding Co., Bay City, Mich.; placed in service 7 June 1941 in the 3d Naval District, New York, 'where she performed various harbor duties throughout her entire service'; reclassified YTB-151 on 15 May 1951; again reclassified YTM-151 during Feb. 1962; and 'in 1967 continues in service in the 3d Naval District, New York, N.Y.' Spec block: dp. 237; l. 100'; b. 25'; dr. 9'7"; s. 12 k.

- Limitations
- Verbatim DANFS text via two independent transcription mirrors (losthistory.net/hazegray and historycentral.com - both carry '15 May 1951'); no live NHHC entry exists for this hull and no Wayback capture was found, so the transcription could not be checked against the official page. The DANFS entry was written circa 1967 and does not cover her later Pensacola reassignment, 1982 disposal, or post-Navy fate. Contains no asbestos content. The 1951 YTB reclassification date conflicts with the class-wide 15 May 1944 reclass carried on NavSource - see gaps.

- NavSource timeline for this hull (Woban class, built by Defoe Boat & Motor Works, Bay City MI, yard no. 170): laid down 3 October 1940; launched 16 May 1941; placed in service as Konoka (YT-151) 7 June 1941; allocated to the Third Naval District, New York, NY; reassigned to NAS Pensacola, FL (date unknown); reclassified District Harbor Tug, Large, YTB-151 (timeline says 15 May 1944, header designation display says 1951-1962 - see gaps); reclassified District Harbor Tug, Medium, YTM-151, February 1962; placed out of service in 1982; struck from the Naval Register 15 December 1982; disposed of by Navy sale 1984; registered to Brown Marine Service, Inc., Pensacola, FL, as Emma Brown (ON 661544) 1984; resold to an unknown buyer at Mobile, AL, 2001; sunk in the Mobile River in 2001; final disposition - raised and sold to Golding Scrap for scrapping, 2003. Specifications: 218 tons light / 325 tons full load; 100' x 25' x 9'7"; 12 knots; complement 12; diesel-electric, single propeller, 1,000 shp. Photo captions place the hull on trials on the Great Lakes in June 1941 and alongside USS Lexington (AVT-16) at Pensacola circa 1981; one caption notes the 10 January 1951 date on National Archives photo 80-G-40448 is incorrect.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates generally track NVR/DANFS, but the NVR does not cover vessels disposed before 1987 so the 1982 strike and 1984 sale could not be cross-checked there. The 2001 sinking and 2003 scrapping rest on this single source; no USCG casualty report or press record was located. Contains no asbestos content.

[5]Era inference built on: DANFS spec block (1941-built steel harbor tug) and NavSource specifications (diesel-electric, single screw, 1,000 shp) [other_primary]
- Locator
- DANFS spec block; NavSource specifications
- Finding type
- asbestos_application
- Finding
- A diesel-electric harbor tug built 1940-41 sits inside the era when the Navy specified asbestos-containing insulation aboard its vessels; era-standard small-craft applications were thermal insulation around machinery and diesel-exhaust runs, gaskets, valve packing, and electrical insulation. As a diesel-electric craft she carried no steam plant - the boiler and turbine lagging pathway of steam vessels does not apply.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1940-41) and Navy service era (1941-1982).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming Konoka (YT-151/YTB-151/YTM-151) was found in the public sources searched (see search_ledger). CourtListener base queries: 'Konoka' opinion 0 results; 'Konoka' docket 1 result - name collision only (attorney 'Michael Frederic Konopka' in Gomez v. 245 West 51st Street Delaware, LLC, 1:24-cv-03080, S.D.N.Y., an unrelated 2024 premises case); 'YT-151' opinion 142 results and 'YT-151' docket 9,438 results - all token collisions on '151' in citations/docket numbers, none naming the vessel; asbestos-qualified variants '"YT-151" asbestos' (opinion and docket, run because both base queries overflowed) each returned 0 results.
