- Documented for this hull: 'The first Rhea (AMc-58) was laid down as a wooden purse-seiner, Hull No. 250, by the Martinolich Shipbuilding Co.; purchased on the ways by the Navy 31 December 1940 and designated AMc-58, named Rhea, 5 March 1941; launched 9 August 1941; sponsored by Miss Marjorie Strong; and placed in service 15 October 1941.' Fitted out at San Diego; equipped with acoustical, magnetic, and 'O'-type gear; remained on the west coast at San Francisco until sailing west in early March 1942 for the 14th Naval District; arrived Pearl Harbor 11 March 1942 and operated in Hawaiian waters until returning to San Diego after the end of World War II. Placed out of service 22 January 1946; struck from the Navy list 7 February 1946; released to the Maritime Commission 30 December 1947; subsequently sold to Demiter J. Callian. Spec block: dp. 340; l. 98'6"; b. 24'; dr. 11'; s. 10 k.; cl. Rhea.

Displacement conflicts with DANFS (307 t. vs 340 tons) - both carried, flagged in gaps. Yard location given as Tacoma; Wikipedia's Dockton categorization conflicts (see gaps).

Martinolich | Fishing Vessel | 307 | 98 | 1941 | To USN 1942 as Rhea (AMc 58), sold 1946 as Elena' - under the page's 'War-Time Construction in Tacoma WA' section, confirming the Tacoma yard (1112 Alexander Avenue, Blair Waterway) as the build site, the official number 256534, the original commercial owner (A. C. Martinolich), and the 307-GT / 98-ft purse-seiner design. Hull 251 (Speaker, O.N. 256152) is the near-identical sister that became USS Ruff (AMc-59).

[5]Era inference built on: DANFS/NavSource construction record (wooden purse-seiner conversion, Superior L.D.P. diesel); NavSource specifications (single 465 bhp diesel, one shaft, complement 17); GAO HRD-80-2 Navy-wide asbestos-era documentation (see ev-uss-rhea-amc58-05) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel coastal minesweeper built 1940-41 and in Navy service 1941-46 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this type and period were engine exhaust lagging, engine-room insulation around the exhaust manifold, gaskets, valve packing, and electrical insulation. As a single-diesel wooden vessel she carried no steam plant and no boiler/turbine lagging pathway, and her 98-ft hull and 17-man complement bound any plausible application scope far below that of steel steam combatants.

- Limitations

Names era-standard applications, not confirmed installed materials; the wooden fishing-vessel conversion may have carried less than even this modest list. No quantity, no manufacturer attribution, no present-day presence.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1940-41) and service era (1941-46).

[7]National Archives, 'An Introduction to Navy Deck Logs' - retention policy for commissioned vs in-service vessels (verified live 2026-10-05) [other_primary]
- Locator
- archives.gov/research/military/logbooks/naval-deck-logs, 'in service' retention paragraph
- Finding type
- historical_record
- Finding
- NARA documents why this hull leaves essentially no operational paper trail: 'only deck logs of commissioned Navy ships are retained permanently... Most service vessels... are classified as "in service" instead of "in commission" and do not possess their own administrative identity. Instead, they report through a higher-echelon parent command. While "in service" vessels may produce logs that are submitted to their parent command, those logs are not retained as permanent records.' DANFS records Rhea as 'placed in service' throughout, never commissioned - so the standard deck-log research avenue is largely foreclosed for this hull.

- Limitations
- Policy documentation applied to this hull's documented in-service status - not a finding that zero records exist. The WWII era is a partial exception per the same page (parent-command records may survive in 14th Naval District files); a parent-command paper trail remains an open archival lead. No asbestos content.

- DISAMBIGUATION for name-collision discipline: the second USS Rhea was a different hull - laid down 5 June 1942 by William F. Stone and Sons Co., Oakland, CA as YMS-299; commissioned 7 April 1943; named Rhea and reclassified AMS-52 on 1 September 1947 as a Naval Reserve training ship in the 4th Naval District (Philadelphia); recommissioned 15 November 1950; reclassified MSC(O)-52 on 7 February 1955; decommissioned 23 December 1957; struck 1 November 1959; sold 1960; Canadian civilian owners; sank 1997 and was raised and scrapped. Any record or litigation naming a 'USS Rhea' post-1947 must be checked against this hull, not AMc-58.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or qualifying litigation naming USS Rhea (AMc-58) was found in the public sources searched. CourtListener ran clean: 'USS Rhea' returned zero opinion and zero docket hits; 'AMC-58' returned one opinion hit (Southport Transit Co. v. Avondale Marine Ways, 234 F.2d 947 (5th Cir. 1956) - a shipyard-fire divided-damages appeal in which the match is an 'AMC' American Maritime Cases reporter citation, not the hull; name collision / other litigation, not asbestos) and nine docket hits (patent, bankruptcy, securities, and antitrust dockets where 'AMC-58' appears as a component/exhibit string - all name collisions, none asbestos, none referencing this hull). The only 'asbestos aboard' material naming AMc-58 is law-firm marketing content (duboselawfirm.com coastal-minesweeper listicle) asserting asbestos without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - CourtListener coverage is opinion/docket text search only (pre-2000 asbestos personal-injury claims largely settled without written opinions, and MDL-875 pleading lists are not exhaustively indexed). The wooden-hull diesel configuration bounds plausible applications to a short era-standard list; absence of records is expected for a 98-ft in-service craft that left no retained logs and was sold to fishing service by 1949. Does not establish or defeat any claim of exposure or legal eligibility.
