- Finding
- NARA holds U.S. Navy deck logs for YMS-208 covering 1943-02-22 through 1944-03-27 - the entire interval from two days after completion to the date of transfer to France - indicating continuous U.S. Navy custody of the hull for the whole period during which secondary sources claim she was 'transferred to Britain 1943'.

- Limitations
- SL44 documents the existence and date-span of logbooks, not their content; log entries were not read (WWII-era RG 24 Entry 118 logs for this hull are not digitized). Deck-log custody establishes U.S. custody/status but does not by itself prove operational employment. Does not establish asbestos presence or absence.

- Finding
- uboat.net lists the hull as a U.S. Navy warship: USS YMS-208, built by Robert Jacob Inc. (City Island, New York), ordered 14 Mar 1942, laid down 19 Apr 1942, launched 8 Aug 1942, commissioned 20 Feb 1943, end of service 27 Mar 1944 - 'Transferred to France on 27 March 1944 being renamed Genet'. The page is filed under the US Navy only; no Royal Navy service is recorded.

- Limitations
- uboat.net is a highly-regarded secondary compilation, not a primary archive; the 'commissioned 20 Feb 1943' field is a compilation value (NavSource says 'completed' the same date) and its laid-down date (19 Apr) conflicts with NavSource (16 Apr). No asbestos information.

- YMS-1-class auxiliary motor minesweeper: laid down 16 April 1942 as YMS-208 by Robert Jacobs, Inc., City Island, NY; launched 8 August 1942; completed 20 February 1943; transferred to France 27 March 1944 as Genet (D 272); sold to France 21 March 1949; struck from the Naval Register 28 April 1949; reclassified D-355, D-11 and M-651; decommissioned 30 November 1961; fate unknown. Specs: 270 t, 136 ft, 24 ft 6 in beam, 15 kts, complement 32, one 3"/50, two 20 mm, two depth-charge projectors, two GM diesels on two shafts. Page displays only U.S. and Free French flags - 'YMS-208 served the Navies of the United States and France' - and states no DANFS history exists for this hull.

[5]NavSource Online Mine Warfare Vessel Photo Archive - Auxiliary Motor Minesweeper (YMS) / British Motor Minesweeper (BYMS) index (verified live 2026-10-04) [other_primary]

- index row 'BYMS-2207 & BYMS-2208 - Pennant numbers not used' (11/19idx.htm); corroborating: Wikipedia YMS-1-class minesweeper RN list; uboat.net ship/9628
- Finding type
- vessel_history
- Finding
- The NavSource index entry reads 'BYMS-2207 & BYMS-2208 - Pennant numbers not used' - unlike sisters listed with their actual Royal Navy J-series pennants (e.g., BYMS-2209 ex-J-1009). The Royal Navy section of the Wikipedia YMS-1-class ship list likewise skips BYMS-2207 and BYMS-2208, and uboat.net files YMS-208 solely under the US Navy with no RN entry. The 'BYMS-2208' Royal Navy pennant carried by secondary compilations ('to Britain 1943 as BYMS-2208') was an administrative Lend-Lease allocation that was never exercised - the hull remained under U.S. Navy custody (per the deck-log span) until transferred directly to France.

- Limitations
- A 'pennant number not used' index note is a compile-time determination, not a scanned RN document; it is nonetheless corroborated by the uninterrupted USN log coverage (SL44), uboat.net's USN-only listing, and the Wikipedia RN roster omission. The administrative allocation itself is real - records may carry BYMS-2208 for this hull even though she never sailed under it. No asbestos information.

- Finding
- French-service chronology: ceded to France 27 March 1944 as D 272; renamed D 355 in 1945; renamed Gênet and assigned M 651 in 1947; reformé 30 November 1961 (Del Boca; consistent with NavSource). Per the postenavalemilitaire fiche, she joined the 35th Minesweeper Division at Oran, participated in sweeping the port of La Pallice (La Rochelle), and later became a trials vessel of the C.E.P.G.M. (Commission pour la Guerre des Mines); that fiche lists désarmé 23 September 1970 and hull symbols D272, D355, D11, M651.

- Population
- French Navy crews, 1944-1961/1970; French yard workers during refits; Oran and La Pallice personnel
- Limitations
- Both are enthusiast/philatelic compilations, not official French Navy publications; the Oran/La Pallice/CEPGM service detail and the 1970 désarmé date rest on postenavalemilitaire alone and conflict with the 1961 reformé date (see gaps - possibly the 1961 date ends frontline service and 1970 ends experimental employment). No asbestos information; French asbestos-regulation context is not documented for this hull.

- Finding type
- vessel_history
- Finding
- Class and builder context: 561 wooden-hulled 136-ft YMS/BYMS minesweepers were built 1942-1945 at 35 yacht yards; YMS-208 is of the single-stack YMS-135-subtype. The Robert Jacob yard (est. 1850s; owned by Robert Jacob from 1900; WWI subchaser builder; sold to Consolidated Shipbuilding 1946) built YMS-207-362 and related hulls at City Island. Of the class, 70 hulls were designated BYMS on the Navy List at U.S. number +2000 for Royal Navy transfer - the administrative scheme under which 'BYMS-2208' was allocated; another ~30 went to the Free French Navy in 1944, the group this hull actually joined.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, medical record, or docketed case naming YMS-208, BYMS-2208, or Genet/M 651 was found in the public sources searched (see search_ledger). Web asbestos queries returned only law-firm marketing listicles addressing minesweepers generically - none names this hull and none cites a primary source; all excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-built diesel combatant could still carry era-standard asbestos components. The hull's WWII-era deck logs (physical, undigitized) and French SHD archives are the unexamined leads. Does not establish or defeat any claim of exposure or legal eligibility.

(2) French Navy records for Gênet/D272/D355/M651, including any refit and matériel documentation for the 1944 transfer and post-war experimental service, would be held by the Service historique de la Défense - Marine (Cherbourg center holds Marine nationale archives).
