[1]DANFS, 'Nightingale' (AMc-18) entry - transcription mirror at hazegray.org, Wayback capture 2024-05-26 (live NHHC DANFS URL returned 404) [nhhc_danfs]

- DANFS AMc-18 entry, full text (two paragraphs plus spec line: dp. 197; 83'2"; b. 19'6"; dr. 9'5"; s. 11 k.; cpl. 17; a. 2 mg.)

- Finding
- DANFS: the third Nightingale (AMc-18) was built by Al Larson Boat Building Co., San Pedro, CA in 1934 as Majestic, a wooden-hulled, diesel-powered purse seiner; acquired by the Navy from Klemente Zar at Western Boat Building Co., Tacoma, WA, 5 November 1940; commissioned 31 January 1941. She operated as a coastal minesweeper in the Puget Sound area, then entered the Western Boat Building yard 'in May' for alteration to a patrol craft and was reclassified YP-166. The name Nightingale was cancelled for YP-166 and reassigned to AMc-149 on 22 April 1942. YP-166 served as a training craft in Puget Sound until 14 October 1944, when she was struck from the Navy List and returned to her owner.

- NavSource detail beyond DANFS: the vessel struck a buoy near the Columbia River bar on 26 December 1941 and sank in the Columbia River (photo shows only her mast above the surface); she was raised and repaired, then served as a training craft in Puget Sound until October 1944. Post-Navy chain: decommissioned and struck 14 October 1944; transferred to War Shipping Administration July 1945 and returned to owner Western Boat Building Co., Tacoma; acquired 1945 by Arthur W. Nyquist of Seattle and renamed Majestic; acquired 1947 by John B. Jorgensen of Seattle; stranded 12 August 1956 approximately 12 miles from Pualle Bay, Shelikof Strait, AK.

- Shipbuilding History's coastal-minesweeper table lists 'AMc-18 Nightingale, Larson Boat Shop, Al, 83 ft, 197 tons, 1934, ex-Majestic, acquired 1940, YP-166 1941, returned to owner 1945'. The same page documents program context: 70 wooden-hulled coastal minesweepers were built in 15 boatyards to the single 97-ft Accentor-class design, and in addition 45 fishing vessels were acquired and converted - placing this hull among the one-off fishing-vessel conversions, not a named class.

- Finding type

- Finding
- Source discrepancy on the YP-166 reclassification date: NavSource and Shipbuilding History read DANFS's undated 'In May' as May 1941, but NavSource's own note reports that the Naval Vessel Register of 1 January 1949 lists the reclassification date as January 1942. DANFS does not give a year; the name cancellation/reassignment to AMc-149 is separately dated 22 April 1942.

- asbestos_application
- Finding
- Era-level inference only: peer-reviewed scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the program and period under which this 1940-41 naval conversion was executed. For this specific hull the inference surface is narrow: DANFS/NavSource document a wooden-hulled, diesel-powered vessel with no boilers or steam plant, so the dominant steam-ship asbestos vectors (boiler insulation, steam-line lagging) were absent. Candidate period applications, if any, would be limited to engine exhaust lagging, gaskets/packing, electrical insulation, and friction linings - none documented aboard this hull.

- Program/era-level scholarship plus documented propulsion facts; no design, specification, survey, or product document names this hull. Asbestos presence aboard this vessel is unproven and the diesel plant narrows it materially; does not establish presence, quantity, exposure, or causation for any individual.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or court record naming this hull (as Nightingale, AMc-18, YP-166, or Majestic) was found in the public sources searched. The CourtListener opinion API was rate-limited at batch time (see search_ledger sl-06); a scoped web-index check of courtlistener.com surfaced only name collisions (Nightingale corporate/healthcare parties, persons surnamed Nightingale) and no case naming the vessel.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - 1940s naval conversions of even small craft are not documented material-by-material in public sources, and the hull is unrecoverable (stranded Alaska 1956). Does not establish or defeat any claim of exposure or legal eligibility. CourtListener result reflects a search conducted under shared-quota constraints; a same-day re-run is queued if quota resets within the batch window.

- Finding
- Name-lineage disambiguation: HyperWar's 'Ships of the U.S. Navy, 1940-1945 - Minecraft' table lists two Nightingales as separate hulls - AMc-18 (ex-Majestic, 1934; converted to patrol vessel YP) and AMc-149 (ex-St. Francis, 1940; converted to unclassified auxiliary IX-177). DANFS dates the name Nightingale's reassignment from this hull to AMc-149 as 22 April 1942. The IX-177 record in this database is therefore a different hull, not a duplicate.
