A deck log is an operational record and would not normally record construction materials. Does not establish any asbestos content.

- The awards-manual transcription credits this hull with World War II operation participation: P30-2 capture and occupation of southern Palau Islands (6 Sep - 14 Oct 1944); P34-1 assault and occupation of Okinawa Gunto (27 Jun - 30 Jun 1945); P35 3d Fleet operations against Japan (5 Jul - 31 Jul 1945); P207-23 'Skagway' East China Sea-Ryukyus area (14 Aug - 15 Aug 1945); P207-2 Tokyo Bay, Honshu area (25 Aug - 3 Sep 1945). The record is consistent with the Pacific minesweeping career implied by the deck-log window and Tokyo Bay presence.

- Finding
- The builder's yard list records this hull: YMS-390, US Navy minesweeper, 278 tons, delivered 30 August 1943, 'sold 1947'. The yard history notes Stadium Boat Works was started as Stadium Yacht Basin around 1935 at the foot of West 3rd Street, Cleveland, and closed in 1957; the table documents the yard's wartime output of YMS-class minesweepers (YMS-76 through -83, -235 through -240, -389 through -392, -414 through -417, -460/-461, and related hulls) - Cleveland Historical independently records the yard built 26 minesweepers for the US Navy.

[9]Era inference built on: NavSource/uboat.net/shipbuildinghistory specifications (wooden-hulled YMS-1 class, twin GM 8-268A diesel plant, no steam); GAO HRD-80-2 (see ev-uss-yms-390-09) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel motor minesweeper built 1942-43 sits inside the Navy's documented asbestos-use era. Era-standard applications aboard a small diesel combatant of this type and period were engine and exhaust thermal lagging, machinery and flange gaskets, valve stem packing, electrical cable insulation, winch and windlass brake linings, and interior deck-covering compounds. As a diesel vessel she carried no boilers or steam turbines - the boiler/steam-line lagging pathway of steam ships does not apply, though small-craft confined spaces (engine room, accommodation trunk) concentrated whatever asbestos products were installed.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming YMS-390 was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried at research time - the helper script reported the fleet-wide pacing budget spent on each attempt; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case and no law-firm 'asbestos aboard' listicle naming this hull was located.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1942-43 Navy combatant is era-consistent with asbestos products, and the litigation repository search is a genuine open gap (pacing-blocked, not run). Deck logs (RG 24, 2/1/1944-6/30/1945 coverage), builder records, and any WSA sale file are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
