- NavSource is a volunteer-run archival compilation transcribing official Navy records and photo captions - not itself a government record. No DANFS entry exists for this hull (NavSource states none available). Decommissioning is given only circa the postal-cover date; register data (ev-02) records a two-step decommission/in-service sequence. Establishes no asbestos information.

- Third-party transcription of official Navy register entries - terse register data; wartime operating assignments and any materials/insulation detail are not recorded. The in-service interval (Aug 1946 - Mar 1947) between decommissioning and final out-of-service explains but does not erase the conflict with the 8 Mar 1947 postal-cover date used by NavSource. Post-sale fate not recorded.

- Philatelic data, not a register entry - the 8 Mar 1947 cover date is best read as approximating the hull's final in-service window; the Shipscribe register transcription records the finer chain (decommissioned 24 Jul 1946, in service Terminal Island from 15 Aug 1946, out of service 26 Mar 1947). Discrepancy retained rather than resolved.

[7]Shipscribe.com, ATR-1 class notes - BuShips chief's 12 Sep 1941 letter to CNO on rescue-tug need; CNO directed ATR 1-40 construction 19 Jan 1942 under the Maximum War Effort (1799 Vessel) Program; Navy decision to build the class of wood with relatively simple triple-expansion steam machinery so small shipbuilders and local machine shops could produce them; design attributed by one source to the John G. Alden firm [other_primary]

- Finding
- Class-level documentation of the ATR-1 design rationale: eighty 165-foot wooden-hulled rescue tugs with 1,600-hp vertical triple-expansion steam plants, built by small yards under the 1942 war program; the design deliberately used wood hulls and simple steam machinery to keep the rescue-tug program out of the main steel-ship effort. ATR-24 is a member of this class (FY1942 group, Fulton Shipyard).

- asbestos_application
- Finding
- The hull's steam propulsion plant is documented ship-specifically (ev-01, ev-02): two oil-fired boilers supplying saturated steam at 200 psi to a reciprocating engine, built to Navy specification in 1943-44. Boiler insulation, steam-line lagging, valve and flange gaskets, and machinery packing of this era and plant type commonly contained asbestos; towing/winching machinery carried brake linings of the same era. Typical applications for a plant of this type: boiler and steam-drum insulation; steam-line lagging in machinery spaces; gaskets and packing throughout the steam cycle; insulation in accommodation and galley spaces.

The documented plant establishes a candidate asbestos pathway, not asbestos presence aboard this hull; the wooden hull reduces but does not eliminate candidate applications. Does not establish quantity, present-day presence, or any individual exposure.
