- Finding type
- vessel_history
- Finding
- NHHC photograph NH 98389 identifies Ganadoga as harbor tug YTB-390 and records her assisting USS Canberra (CAG-2), with Segwarusa (YTB-365), at the International Naval Review in Hampton Roads, Virginia, on 12 June 1957.

- Limitations
- The official NHHC indexed caption identifies the vessel and dated activity, but the live page returned HTTP 404 during direct retrieval, so the photograph was not inspected. The caption does not establish construction date, full service history, machinery, crew, insulation composition, asbestos exposure or later disposition.

- Finding type
- vessel_history
- Finding
- NAVSEA's 28 June 2011 inactive-ship history index lists hull YTM 0390, name GANADOGA, removal date 19 July 1977, and final disposition UNK.

- Limitations
- The official PDF's indexed text supplies this row, but the file returned HTTP 403 during direct retrieval, so its page layout was not independently inspected. 'Removal' is not necessarily the decommissioning date. UNK does not prove any particular fate, including a reported target sinking in 1980. No asbestos information is present in the indexed row.

- 1920-1950 section, paragraph beginning 'As the world entered World War II'
- Finding type
- asbestos_application
- Finding
- NIOSH's historical account states that U.S. Navy use of asbestos for pipe insulation in naval vessels increased as World War II began; it also describes Navy recognition of dust risk when working with asbestos-containing insulation.

- Navy shipbuilding and shipboard workers in the World War II era, generally
- Limitations
- Broad Navy-era history only. It does not mention Ganadoga, harbor tugs, this class, or Consolidated Shipbuilding; it cannot establish that any asbestos product was installed, disturbed or retained aboard this hull, or that any person was exposed.

[4]Batch 9369 search ledger: NHHC photo, NAVSEA inactive-ship index, NARA lists and CourtListener authenticated searches [other_primary]

- Finding type
- historical_record
- Finding
- No hull-specific asbestos survey, material specification, abatement record or verified asbestos litigation was located in the official sources and completed CourtListener searches logged below. The remaining hull-designation litigation searches could not be completed because the fleet pacing limiter repeatedly deferred requests before HTTP.

- Limitations
- This describes the bounded search, not proof that asbestos was absent. The exact-name opinion and docket searches and YTM-390 opinion search returned zero results; other hull-designation searches remained incomplete after repeated fleet pacing deferrals. The row and ledger must be updated if later searches return hits.

- Finding type

- Finding
- NARA's RG 181 guide identifies Fifth Naval District commandant files in Philadelphia and Sixth Naval District records in Atlanta as archival research paths for district-craft operations and maintenance; no Ganadoga-specific file was retrieved.

- Limitations
- The guide identifies record series, not an item for this vessel; whether those files contain plans, work orders, asbestos records or service details is unknown. The district assignment itself is a secondary-source lead awaiting official verification.

[6]National Archives, Special List 44: Named Vessels and Ship Number lists of Navy logs, 1801-1947 [other_primary]
- Locator
- Named-vessel page search for Ganadoga; hull-number PDF https://www.archives.gov/files/research/military/logbooks/sl-44-ship-number.pdf, searches for YT-390 and YTB-390
- Finding type
- historical_record
- Finding
- Ganadoga does not appear in NARA Special List 44's online named-vessel list for Navy logbooks through 1947, nor was YT-390 or YTB-390 found in its hull-number list.

- 1801-1947 list coverage
- Limitations
- A negative result in this particular list does not prove no deck logs exist, especially because this was an in-service district tug and the list ends in 1947. Deck logs would document operations, not necessarily construction materials or asbestos.

- Section 19.8.5, Records of the Shipbuilding Division
- Finding type
- historical_record
- Finding
- NARA's Bureau of Ships guide identifies Record Group 19 Shipbuilding Division material specifications (1909-1944) and indexed U.S. Navy vessel plans (1908-1959) as possible construction-material research paths; no Ganadoga plan or specification was retrieved.

- Limitations
- The record-group guide gives general series coverage, not a Ganadoga item. Inclusion of this tug in the plan index, and the content of any such item, remain unverified; no asbestos finding follows.

- Limitations
- The negative online-index search does not prove that no plans or specifications exist in RG 19 or elsewhere; the index may omit records or use another filing designation. It provides no evidence about asbestos materials aboard the vessel.
