There is NO 'AMC-146' entry in the index: logs for the minesweeper-designation phase (Dec 1941 - May 1942) are not indexed, and the final months of service (April - November 1944, through the stricken date) are likewise unindexed. The logs are physical holdings; the NARA digitized-deck-logs page lists no YP-384 among digitized logs.

    Secondary compilation (volunteer-edited naval-history reference), not a primary record. Its Tacoma-1940 build is corroborated by the independent shipbuildinghistory table (ev-06); the May 1942 reclassification is consistent with the SL-44 deck-log run beginning 5/19/1942 (ev-02); and the February 1945 WSA transfer is consistent with the official 'returned' annotation (ev-03). Its acquisition year '1942' conflicts with the official 'Dec. 10, 1941' (ev-01), and its spec block (80 t, 76 ft, 24 ft beam) partially conflicts with both the official 75 ft 10 in x 21 ft 6 in and shipbuildinghistory's 73 t - secondary figures carried flagged, not asserted. Contains no asbestos information.

    Finding
    Design-level assessment of the asbestos-relevant profile: this craft carried a single diesel engine on one shaft in a ~73-80 ton wooden fishing-type hull - no boilers, no steam distribution system, no turbines (Ships' Data 1943 diesel entry; secondary spec blocks concur). The principal asbestos vectors documented aboard steam-era naval vessels - boiler and steam-drum lagging, steam-line insulation, turbine and condenser insulation - are absent by design in this type. Residual era-typical applications remain plausible but are undocumented for this hull: diesel exhaust and muffler insulation, engine gaskets and packing, electrical insulation, joiner materials, and brake linings on winch/windlass gear.

    Limitations
    Design inference, not a ship-specific finding: the absence of a steam plant removes the dominant asbestos vectors but does not prove the absence of asbestos aboard - WWII-era gaskets, packing, electrical components, and interior materials could still contain asbestos, and whatever conversion/outfitting the Navy added is undocumented. No located source names an asbestos product installed on this hull. Does not establish presence, absence, exposure, or causation for any individual.

    Finding
    Publication-level discrepancies reconciled or logged: (a) Dimensions/tonnage - official Ships' Data 1943 gives 75 ft 10 in x 21 ft 6 in; NavSource gives 76 ft / 24 ft beam / 80 t; shipbuildinghistory gives 76 ft / 73 tons. The official figures control; secondary figures carried flagged. (b) Acquisition event - Ships' Data 1943 records 'Acquired Dec. 10, 1941'; NavSource says 'acquired by the Navy in 1942.' The WSA small-craft requisition pattern documented for sister YP-383 (bill of sale formalized 13 June 1942) suggests a Dec-1941 takeover/requisition with purchase paperwork completed in 1942 - both dates defensible at different stages, unresolved which event 'acquired' denotes. (c) Disposal - official 'returned' annotation + 27 Nov 1944 strike vs NavSource 'War Shipping Administration, February 1945' vs shipbuildinghistory 'to MARAD 1945' - consistent disposal story with agency-label variance.

    Absence of a located public record does not prove absence of asbestos aboard - period small craft commonly carried asbestos gaskets, packing, and hot-surface insulation. Does not establish that asbestos was or was not fitted, nor any individual exposure or legal eligibility. The CourtListener vessel-name search was rate-limit blocked at research date, so the litigation surface is a flagged gap rather than a confirmed null.
