- Finding
- NavSource's hull page identifies YMS-29 as a YMS-1-class auxiliary motor minesweeper laid down 30 January 1942 by Greenport Basin and Construction Co., Long Island, New York; launched 11 April 1942; and completed 29 July 1942. It records transfer to France on 2 October 1944 as Jasmin (D 335), sale to France on 21 March 1949, strike from the Naval Register on 28 April 1949, later French designations D-23 and M-663, French decommissioning on 5 June 1963, and fate unknown.

- YMS-29 crew; Greenport construction workforce
- Limitations
- NavSource is a maintained photo archive rather than a primary Navy construction or transfer record. It says 'completed,' not 'commissioned'; no commissioning document was located. This history does not establish asbestos conditions aboard.

- This is an inventory, not the deck-log contents. The listed logs were not examined and the online NARA deck-log list does not identify YMS-29 as digitized. The coverage date is not a commissioning or decommissioning date.

- Finding type
- vessel_history
- Finding
- The official ship-level engagement-star list in NAVPERS 15,790 credits YMS-29 with West Coast of Italy operations (E4, 22-28 January 1944), Anzio-Nettuno advanced landings (E4-1, 25 February-1 March 1944), and the Invasion of Southern France (E7, 15 August 1944-September 1944). Under the manual's one-star-per-operation rule for the E4 group, E4 and E4-1 together represent one engagement star; E7 is a second.

- The transcription preserves the source's imprecise E7 end date ('Sep 44'). It documents campaign participation, not asbestos conditions or individual exposure.

- Finding type
- vessel_history
- Finding
- Class context: NavSource describes YMS vessels as wooden-hulled 136-foot motor minesweepers built at small yacht and boat yards. YMS-1 through YMS-134, the group containing YMS-29, had two stacks; class characteristics list General Motors 8-268A diesel engines and two shafts.

[6]Inference from NavSource YMS-29 hull specifications and YMS/BYMS class index [other_primary]
- Locator
- Inference from ev-uss-yms-29-01 and ev-uss-yms-29-04 design data
- Finding type
- asbestos_application
- Finding
- Class/era inference: this wooden-hulled diesel motor minesweeper had no steam plant. The asbestos-relevant systems on a vessel of this type and period could include diesel exhaust lagging, engine and machinery gaskets and packing, electrical insulation, and brake linings on the sweeping winch and windlass. Its compact diesel plant presents a materially smaller asbestos-relevant equipment set than a contemporary steam-powered hull.

- Limitations
- No hull specification sheet, builder work package, survey, maintenance record, or test result naming YMS-29 was located. This does not establish that asbestos was installed aboard in any quantity, or that it was not.

- historical_record
- Finding
- No ship-specific asbestos record was located in the completed non-CourtListener public-source searches: no asbestos survey, abatement contract, hazmat disclosure, DANFS history, or public official source documenting asbestos aboard YMS-29 was found. CourtListener sweep status is recorded in the search ledger.
