[2]NARA Special List 44: List of Logbooks of U.S. Navy Ships, Stations, and Miscellaneous Units, 1801-1947 - ship-number list (NARA spreadsheet PDF) [other_primary]
- Locator
- sl-44-ship-number.pdf, PDF page 116, row 'YMS-235 7/27/1943 6/30/1945' (retrieved file byte-identical to NARA master, MD5 639e2f288db3e0c7a8e7489a0b57bf07)
- Finding type
- historical_record
- Finding
- NARA Special List 44 records US Navy deck logs for YMS-235 covering 27 July 1943 through 30 June 1945 - the vessel's WWII service period from shortly after completion through the end of the war. The logs are extant in National Archives custody (RG 24) but were not retrieved for this record.

- Population
- YMS-235 crew (deck-log subject population)
- Limitations
- Confirms the existence and date coverage of deck logs, not their contents - the logs themselves are not digitized and were not reviewed. Coverage ends 30 June 1945, so the vessel's post-surrender minesweeping service (September 1945) and 1946 status are outside the listed holdings (postwar logs are held under a different series). No asbestos information.

- The official awards manual lists 'YMS 235: 17 Feb 45 - 16 Mar 45 P33-1; 4 Sep 45 - 8 Sep 45 P207; 11 Sep 45 - 14 Sep 45 P207' - engagement star P33-1, 'Assault and occupation of Iwo Jima' (operation window 15 Feb - 16 Mar 1945), placing this hull in the Iwo Jima operation; and engagement code P207, Minesweeping Operations Pacific, for two post-surrender windows in September 1945.

- Limitations
- Verbatim transcription of an official Navy manual hosted on the HyperWar project (ibiblio) - ship-specific and authoritative for the engagement-star award, but the manual records eligibility dates, not the vessel's day-to-day positions or actions. The P207 windows post-date the listed deck-log coverage. Contains no asbestos information.

- Population
- YMS-235 crew (complement 32 per class spec block)
- Limitations
- NavSource is a secondary compilation, not an official source - dates trace to NVR/DANFS-derived records but the underlying register page for this hull was not directly retrieved (NVR online covers modern dispositions only; this hull was stricken 1946). 'Completed 20 July 1943' is treated as the in-service date; commissioning-vs-completion wording differs across secondary sources. No asbestos content.

- University maritime-archive registry independently confirms hull identity and construction: rig 'Yard Minesweeper', U.S. registry, hull material wood, dimensions 136.0 x 24.5 x 8.0 ft, builder Stadium Boat Works, Cleveland, OH, built 1943; disposition 'Stricken from Navy List on August 28, 1946; sold in April, 1947. Ultimate disposition unknown.'

- Limitations
- Archival registry entry corroborating identity and wooden construction - consistent with NVR-derived data but is itself a compiled registry, not a contemporaneous hull record. Confirms wood hull (relevant to asbestos inference - no steam plant, limited machinery lagging). No asbestos information.

Same page records: ordered 14 March 1942; laid down 4 July 1942; launched 15 February 1943; commissioned 20 July 1943; stricken 28 August 1946; sold April 1947.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming YMS-235 / USS YMS-235 was found in the public sources searched (see search_ledger). All four CourtListener base queries (exact-name and hull-number, opinions and dockets) returned zero results - no collisions or litigation of any kind indexed under this hull designation.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era construction practice is consistent with some asbestos-containing components even on small diesel minecraft. Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility.
