- Establishes identity, milestones, wartime employment, decommissioning, and disposal. Contains no asbestos, insulation-material, or crew-health information; supports no asbestos claim. Live NHHC page 404s (known link-rot pattern noted in Batch-01); citation runs through a Wayback capture of the official NHHC page. DANFS gives no keel-laying or reclassification date - those come from register-derived data (ev-02).

- Private-site reproduction of official Naval Vessel Register data - content is register-derived but the site is a secondary mirror, not a .mil domain. Establishes keel date, reclassification, strike date (20 Mar 46, which NavSource lists as unknown), and the MC sale to Robert Martinolich - with no asbestos information. Complement shown (43, 1944 class figure) differs from the ship's documented 56 - period/design figure vs. ship's crew, noted in gaps. The buyer's subsequent use of the vessel is not recorded.

- Volunteer-compiled archive - authoritative for the compiled register/photo data it cites but is itself a secondary compilation. Machinery spec (diesel-electric, no steam plant) bounds the ship's insulation profile; contains no asbestos information and supports no asbestos claim. Two conflicts carried in gaps: NavSource credits TWO battle stars (Marianas + Iwo Jima campaign table) where DANFS credits ONE - and the listed Marianas/Guam campaign window (21 Jul-15 Aug 1944) precedes the ship's documented departure from San Francisco (6 Oct 1944), making that campaign attribution suspect; NavSource lists the strike date as unknown where the register-derived Shipscribe table gives 20 Mar 1946.

- Finding type
- asbestos_application
- Finding
- Era/class inference: Canotia was built in 1944 at a Navy-funded emergency shipyard (Everett-Pacific, Port Gardner Bay) during the period when the U.S. government had reserved asbestos supply for shipbuilding and asbestos was a standard insulation/fireproofing material in U.S. naval and merchant construction. A diesel-electric auxiliary of this size would have had no boiler/steam-main insulation load; era-typical asbestos applications for the type would have been exhaust and machinery-space lagging, gaskets and packing, electrical insulation, and joiner bulkhead panels.

- Limitations
- Program/era-level scholarly documentation of asbestos use in WWII shipbuilding generally; does not name this vessel or its class and does not establish that asbestos was installed aboard this hull, nor quantity, location, condition, exposure, or causation. The diesel-electric plant (verified ship-specific, ev-03) means the steam-era boiler-lagging driver does not apply; residual era-typical applications remain inference.

- Finding
- NARA finding-aid confirmation: Special List 44 (List of Logbooks of U.S. Navy Ships, Stations, and Miscellaneous Units, 1801-1947) lists 'Canotia (AN-7)' logbooks covering 7/31/1944-6/30/1945 - i.e., commissioning through mid-1945. The '(AN-7)' hull number in the finding aid is a truncation/transcription artifact for AN-47: no ship named Canotia ever held AN-7, and the listed begin date is exactly the documented commissioning date (31 Jul 1944) of AN-47. Deck logs for July 1945-February 1946 (post-surrender Carolines sweep, Ulithi/Kossol net removal, inactivation) are not in the Special List 44 entry.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement record, hazmat disclosure, museum documentation, or docketed litigation naming USS Canotia, YN-66, or AN-47 was found in the public sources searched (see search_ledger). The single CourtListener docket hit for 'Canotia' is a name collision - the canotia tree (Canotia holacantha) referenced in Ninth Circuit environmental litigation over the Resolution Copper/Oak Flat project, unrelated to the vessel. The hull was sold to a private buyer in April 1947 and its fate is unknown, so no present-day condition record can be located.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard during her 1944-46 Navy service - 1944 Navy construction was era-typical for asbestos use in secondary applications. Does not establish or defeat any claim of exposure or legal eligibility. NARA deck logs (RG 24) and the Maritime Commission disposal file remain unsearched in paper form; the buyer's identity (Robert Martinolich, San Francisco) is known but no subsequent merchant registry entry was located.
