- Expert secondary compilation transcribing official Navy records, not the primary documents themselves; its keel date (28 Sep 43) conflicts with NavSource (3 Jul 43, which duplicates sister hull ATR-70's keel date) and its builder label 'Bellingham Marine' conflicts with NavSource's 'Bellingham Iron Work Inc.' and MARAD's yard index — all discrepancies carried in gaps rather than silently reconciled. Contains no asbestos, insulation-material, or hazardous-material statement.

- Finding
- A crew-contributed addendum hosted on the NavSource ATR-71 page, prepared in memory of CMM Ray Sullivan (salvage diver, machinist and boiler operator aboard ATR-71) and citing the ship's war diaries, documents: decommissioned November 1946; struck March 1947; sold to George Milburn, Seattle WA, May 1948. Officers listed: LT J. B. Walker (commanding, promoted to LT late 1945), LTjg Edward X. Madruga (executive officer), LTjg Frank Kerestesi, Ensign Edward T. Walsh Jr., Warrant Officer (Machinist) Harold J. Newton. War-diary narrative for the September 1945 typhoon: departed Ulithi 1945-09-12 en route Buckner Bay, Okinawa; typhoon warning received 1945-09-14 with barometer 28.40 and winds estimated 100 knots approximately 300 miles north-northwest of Ulithi — water in all bilges, salvage locker flooded, both masts damaged, salt water grounded out electrical circuits and evaporator motors, an 8,000-lb anchor broke loose damaging capstan, engine-room ventilator and deck, all life rafts and deck-stored gear lost overboard; USS ATR-83 (LT D. J. Coughlin) answered the distress call 1945-09-15, sighted ATR-71 and escorted her back to Ulithi 1945-09-16; moored alongside destroyer tender USS Prairie (AD-15) for repairs 1945-09-18; entered auxiliary repair dry dock ARD-23 at Ulithi 1945-09-26 where workmen replaced sheathing on the port bow. The storm is identified as either Typhoon Ursula or Typhoon Ida, which raged concurrently; the addendum does not resolve which.

Typhoon identity unresolved (Ursula vs. Ida). Repair events at a tender (AD-15) and floating drydock (ARD-23) are documented as events only — no insulation disturbance or asbestos statement appears in the addendum. Contains no asbestos or hazardous-material statement.

- NARA Special List 44 (Logbooks of U.S. Navy Ships and Stations, arranged by ship number) indexes deck logs for ATR-71 covering 1944-10-12 through 1945-12-31 — the hull's entire commissioned period from commissioning day through the wartime deployment and the September 1945 typhoon.

- Finding
- Class-level construction documentation for the type this hull belongs to: shipscribe's class notes state the Navy 'decided to have the vessels built of wood and equipped with relatively simple triple expansion steam machinery' so small shipbuilders and local machine shops could produce them outside the main Navy pipeline; the design is attributed by one source to the John G. Alden firm; CNO directed construction of ATR 1-40 on 1942-01-19 under the Maximum War Effort (1799-Vessel) Program and VCNO directed ATR 50-89 on 1942-08-05 — the batch containing this hull. The wartime Navy publication transcribed at HyperWar ('US Navy Tugs, 1940-45') describes the class as 'Wooden-hulled Rescue Tugs, built to patrol convoy lanes' with triple-expansion reciprocating steam engines, single screw, 1,600 hp, and lists ATR-71 in commission during 1943-45 (list range; actual commissioning 1944-10-12).

The HyperWar '1943-45' column is a generic in-commission range for the list, not a precise commissioning record. No asbestos statement in either source — the fiber content of this hull's boiler/steam-line insulation is not established by any located record.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II, the era and program under which this hull was built (keel laid 1943, commissioned 1944), and that wartime demand drove unprecedented asbestos utilization fleet-wide — including aboard small naval auxiliary hulls built at emergency-program yards such as the one that built this tug.

- CourtListener searches for this hull produced no qualifying asbestos litigation. Opinion-index search for the exact string "ATR-71" returned 1 result — Avocent Redmond Corp. v. Raritan Americas, Inc., 921 F. Supp. 2d 229 (S.D.N.Y. 2013), a patent-infringement and licensing dispute between technology companies; the string appears as a product/exhibit reference, classified as a name collision, not a vessel case. Opinion-index search for "USS ATR-71" returned 0 results. Docket-index search for "ATR-71" returned 2 dockets, both name collisions in unrelated cases (High Yield REO, LLC v. Certain Underwriters at Lloyd's, London, 1:19-cv-12102, D. Mass. 2019, insurance removal; Pacira Biosciences, Inc. v. American Society of Anesthesiologists, Inc., 2:21-cv-09264, D.N.J. 2021) — the string matches exhibit/document codes, not the vessel; none involve asbestos or any ship.

- Sweep covers the CourtListener opinion index for the hull string and the 'USS ATR-71' prefix form and the docket index for the hull string: 0 qualifying results; the 1 opinion hit and 2 docket hits are all classified as name collisions (unrelated cases where 'ATR-71' appears as a product/exhibit/document code). The spaced variant 'ATR 71' was not swept — the fleet pacing budget rejected that query. Zero hits in CourtListener does not exclude state-court filings, unindexed dockets, or MDL-875 pleading-stage references naming the hull.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum/NPS documentation, or litigation naming ATR-71 was found in the public official sources searched. There is no DANFS entry for this hull (NavSource confirms none exists); NARA indexes deck logs and RG 19 plan holdings for the hull but contents are unretrieved; MARAD's Vessel History Database indexes six ATR hulls (ATR-68, ATR-70, ATR-78, ATR-79, ATR-81, ATR-9) but holds no record for ATR-71, consistent with a 1948 Maritime Commission sale to a private buyer leaving no digitized status card; and the Naval Vessel Register categorically excludes vessels disposed before 1987.

- Absence of a located public record does not prove absence of asbestos aboard — a 1944 steam auxiliary is era-consistent with asbestos-containing machinery insulation, and the hull's 1948 private sale with unknown subsequent fate leaves no modern survey window. Does not establish that asbestos is or was present or absent; does not establish or defeat any claim of exposure or legal eligibility. Litigation sweep is bounded as described in ev-10.
