- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII, the era and program under which this 1943-44 Navy auxiliary was built, and that wartime demand drove unprecedented asbestos utilization aboard U.S.-built hulls.

- asbestos_application
- Finding
- The documented machinery for this hull was a fossil-fuel steam plant - two Babcock & Wilcox "D"-type boilers (200 psi, saturated) feeding a Fulton Iron Works vertical triple-expansion engine (1,600 shp) plus two 60 kW turbo-drive generators. Steam systems of this type and era were commonly insulated and sealed with asbestos-containing boiler insulation, pipe lagging, gaskets, and packing. Bounding facts specific to this hull: the ATR-1 class was a wooden-hulled design (narrower structural-insulation scope than a steel auxiliary of comparable size), and the steam plant was removed in a 1950 Fairbanks-Morse diesel repower - confining any era-typical asbestos systems to 1944-1950 and making the repower the most plausible (unrecorded) disturbance/removal event.

- Limitations
- The steam plant itself is ship-specifically documented (class spec sheet names the hull's machinery fit); the asbestos CONTENT of its insulation/gasketing is era inference - no insulation schedule, survey, or material record for this hull was located. Does not establish that asbestos was or remains aboard; the 1950 repower removed the original plant, and any residual materials' presence at the 2008 sinking is unknown. Does not establish individual exposure or causation.

- Finding
- Official Navy data (Ships' Data transcription): ATR-64 decommissioned and placed in service 23 May 1946 at Boston, Mass.; placed out of service 7 March 1947; delivered to the U.S. Maritime Commission 12 March 1947; stricken from the Naval Register 4 April 1947; sold (delivered) by the Maritime Commission to George E. Gilbert, Boston, Mass. Shipscribe's annotation flags that this vessel's subsequent commercial career (Logmac / Mogul / Island Monarch / Seaspan Chinook / La Lumiere, hulk extant 2001 in Howe Sound) is also attributed in some sources to sister ship ATR-65, and vice versa - a documented cross-attribution caveat for both hulls.

- Limitations
- Transcription of official records; the delivery-to-MC date (12 Mar 47) precedes the strike date (4 Apr 47), consistent with custody transfer while still nominally listed - the record does not further explain the sequencing. The ATR-64/ATR-65 commercial-career cross-attribution means post-Navy details from any single secondary source require the registry chain (Canada Official No. 179431) for confirmation; the registry data (ev-06) supports the chain given here. No asbestos information; supports no asbestos claim.

- Finding
- DANFS (Dictionary of American Naval Fighting Ships), entry for USS Billfish (SS-286): 'Following inactivation at Portsmouth Navy Yard (June-October 1946) she was towed to New London, Conn., by ATR-64 and went out of commission in reserve there 1 November 1946.' ATR-64 thus performed a documented in-service tow of a Balao-class submarine in autumn 1946 during her post-commissioning in-service period.

NavSource states explicitly that no DANFS entry exists for ATR-64 itself, and NHHC site search returns none - all ship-specific DANFS coverage of this hull is this single cross-reference.

Owner-date boundaries differ slightly from NavSource (Logmac 1948 vs 1947; Seaspan Chinook 1973 vs 1972); the year-level registry sequence is adopted and the discrepancy noted rather than resolved.
