DANFS adopted as controlling; the 20-December figure appears to propagate a single compilation error. (b) Reserve-fleet layup location - NavSource prints 'Transferred to the Maritime Administration for lay up in the National Defense Reserve Fleet, Olympia, WA'; DANFS and the MARAD card place custody transfer at Suisun Bay, CA, 14 June 1961 (Columbia River Group, Vancouver, WA is the documented 1946-1961 layup group). Suisun Bay adopted; Olympia line treated as compressed/erroneous. (c) NavalCoverMuseum prints permanent custody transfer 1 June 1961; DANFS and MARAD cards give 14 June 1961 (Navy to reserve-fleet custody) and 1 September 1962 (MarAd title). DANFS/MARAD adopted. (d) Wikipedia infobox 'Transferred to the U.S. Maritime Administration, 1 June 1961' - same June-1 anomaly as (c). (e) Final disposition - NavSource prints 'Final Disposition, fate unknown'; DANFS + MARAD cards establish the NTU sale to Zidell Explorations (award 22 January 1976, $10,000, MA-8238/PD-X-1002; withdrawn/delivered 17 February 1976) - 'fate unknown' is superseded.

A 1941 diesel-electric Navy auxiliary of this type is era-consistent with asbestos-containing materials in machinery gaskets and packing, exhaust-system lagging, electrical insulation aboard the generating plant, friction linings on the heavy net-handling winch/windlass and 12-ton boom brake machinery, and interior insulation/deck covering materials - applications documented Navy-wide for the WWII construction era (see ev-07, ev-08).

The 2012 Federal Register Regulated Navigation Area notice (77 FR 19544, CGD11-11-017) likewise describes the property's history of 'shipbuilding and dismantling, scrap metal operations, wire burning' and contaminated soils/sediments requiring an engineered cap.

    Limitations

    Confirms no qualifying ship-specific litigation was located via CourtListener as of 2026-09-24; does not rule out state-court or unindexed federal filings outside CourtListener coverage, and does not evaluate the merits of any case that might separately name this vessel. Litigation-stage discipline: no hit reached even the pleading-allegation stage for this hull, so no stage classification beyond 'no qualifying result' applies. 'Cinchona' is a high-collision term (quinine/pharma subject matter, tariff schedules, personal names) - classification was by identifier co-occurrence, not name alone.
