- Shipscribe is a transcription project of official Navy register/Ships' Data publications, not the register scan itself; the commission date is independently corroborated by NARA deck-log coverage beginning 1944-02-21 (ev-04) and by NavalCoverMuseum (ev-03). The launch date conflicts with two secondary sources - see correction row ev-03. The ship note's 'Decomm. and placed in service 26 Feb 46' is an in-service reduced-status period, distinct from the 20 Jun 46 out-of-service date in the disposition table. Contains no asbestos or materials information; supports no asbestos claim.

- NavSource is a vetted secondary archive, not an official register; its campaign table, commanding officer, call sign, medal-period dates, spec block, merchant rename, and 1974 loss report are single-source here for this hull - the two battle stars are corroborated by NavalCoverMuseum's award list (ev-03). Its construction dates agree with the register except launch (30 Nov vs 10 Nov - see correction row); its 'decommissioned/struck date unknown' is superseded by register dates. The 'sold 1946' summary reads the strike year as the sale year - register custody ran to June 1948. The 1974 burning carries a same-name tuna-clipper collision - see ev-03(d). Contains no asbestos information; supports no asbestos claim.

- Finding
- Source reconciliations for ATR-80. (a) Launch date: register transcription gives 1943-11-10; NavSource and NavalCoverMuseum both give 1943-11-30 - an unresolved one-digit conflict; the register date is adopted as controlling but flagged. (b) Disposal: NavSource and NavalCoverMuseum summarize 'sold in 1946' - the register records the hull out of service 1946-06-20 and struck 1946-07-19 but still in federal custody until MC disposal 1948-06-28 with sale awarded 1948-05-18; 'out of the Navy 1946' and 'sold federally 1948' are both true at different custody stages. (c) Reduced status: the register ship note documents a 'placed in service' period 1946-02-26 to 1946-06-20 - minimum-crew operation in the 13th Naval District 'in connection with laid up ships' - distinct from full decommissioning. (d) Merchant-fate collision: three vessels named Western King operated in Pacific waters - this hull (merchant tug from 1948), a purpose-built 170-ft tuna clipper built 1950 by Western Boatbuilding, Tacoma, and a 1964 Canadian fishing vessel (ON 322411, still extant as IMO 6503896); 'Western King of Seattle' tuna-vessel seizures by Peru and Ecuador (1969-1970 press) most plausibly concern the purpose-built clipper, and whether NavSource's 1974 burning report attaches to this hull or the clipper is unresolved. (e) Boiler pressure: NavSource's spec block for this hull gives 260 psi saturated while the class register figure and sister-hull spec blocks give 200 psi.

- Reconciles loose secondary-source statements against the register: NavSource/NCM 'sold in 1946' reads the strike year as the sale year; the 10-vs-30 November launch conflict is unresolved (register adopted, secondary sources unanimous against it); the 26 Feb-20 Jun 1946 window is an in-service reduced status, not full commissioning. The Western King collision means no post-1948 event (seizures, 1974 burning) can be asserted for this hull beyond the register's documented 'Merc. WESTERN KING 1948' sale. No asbestos content.

- vessel_history
- Finding
- ATR-1 class design/procurement context: BuShips' 1941-09-12 letter to CNO argued the need for rescue tugs to tow disabled vessels; CNO directed ATR 1-40 construction 1942-01-19 under the Maximum War Effort (1799-Vessel) Program and VCNO directed ATR 50-89 on 1942-08-05 (the tranche including this hull, ordered 1942-11-28). To avoid competing with steel combatant construction the Navy built the type with wooden hulls and simple triple-expansion steam machinery, letting small shipyards and local machine shops do the work; one source attributes the design to the John G. Alden firm. ATR 101-140 were redirected to steel construction in 1943 partly over Pacific shipworm concerns. Class service pattern: NHHC's DANFS entry for Narraguagas (AOG-32) places sister rescue tugs ATR-38 and ATR-62 in towing unit TU 30.9.23 in the Okinawa operation, June 1945 - the same operation area where this hull is documented (April 1945 Okinawa Gunto campaign window).

- Class/program-level documentation - establishes design intent and sister-ship employment, not this hull's operations or unit assignment. The Alden design attribution is hedged by the source itself ('one source indicates'). The Okinawa citation names ATR-38 and ATR-62 in June 1945, not ATR-80 - this hull's Okinawa window (1-28 April 1945) is documented only by NavSource's campaign table. No asbestos content; supports no asbestos claim.

- asbestos_application
- Finding
- Era-level documentation: asbestos was used extensively as insulating and fireproofing material in U.S. WWII shipbuilding. Applied to this hull only as inference: a 1944-vintage steam plant (two Foster Wheeler 'D'-type boilers, Prescott vertical triple-expansion engine, single screw) is consistent with period asbestos applications - boiler insulation, steam-line lagging, flange/valve gaskets, machinery packing, brake linings on towing and anchor machinery, and accommodation-space insulation. The class's wooden hull removes the structural-steel fireproofing a steel ship would carry.

- CourtListener sweeps returned no qualifying result for this hull. 'ATR-80' in the opinion index - 1 hit, Avocent Redmond Corp. v. Raritan Americas, Inc. (S.D.N.Y. 2013, patent and licensing dispute): 'ATR-80' is a product model reference, a name collision. 'ATR-80' in the RECAP docket index - 1 hit, MDL No. 875 (In re Asbestos Products Liability Litigation, J.P.M.L. master docket), matched only via OCR text of Exhibit G-37 in the Vest matter - a McDonnell Douglas aircraft-parts drawing bearing asbestos-sheet gasket callouts; the 'ATR-80' string is a drawing/dash-number artifact, not a vessel reference. 'ATR 80' unhyphenated, qualified by asbestos OR Navy OR tug OR vessel, in opinions - 1 hit, the same Avocent opinion. Merchant-name sweep 'Western King' tug OR asbestos in opinions - 13 hits, all other-party collisions except one vessel-connected candidate: Gvirtsman v. Western King Co., Inc. and Peter Pan Caribe, Inc., 263 F. Supp. 633 (C.D. Cal. 1967), a seaman wrongful-death action against the owners of a vessel named Western King - the ownership pair matches the Seattle tuna clipper documented in 1969-1970 press, and whether that vessel was the ex-ATR-80 hull is unresolved (see ev-03d). No asbestos litigation, and no litigation that demonstrably names this hull, was located.

- Limitations
- CourtListener indexes do not cover all federal/state dockets or unreported matters; every located hull-number hit is a name collision - zero qualifying hits for the vessel means no located case, not proof that no claim was ever filed. The Gvirtsman defendants (Western King Co. + Peter Pan Caribe) match the 1969-1970 Seattle tuna-clipper ownership reported in press; whether that Western King is this hull is unresolved - classified down as 'possible vessel-related litigation, hull unconfirmed' rather than asserted as this ship's litigation. The wrongful-death subject matter is not asbestos exposure. PACER was not searched (no spend authorized). A hull-specific absence is consistent with a small, short-lived, unnamed auxiliary disposed in 1948.

- Absence of a located public record does not prove absence of asbestos aboard - a 1944 steam tug is era-consistent with ACM in the machinery spaces, and the hull's loss by fire in 1974 (if attribution holds) ends the modern exposure question rather than resolving it.
