- Primary government custody document. Identifies the Maritime Commission requisition of the fishing vessel Pacific Star from private owner Sam Lonero at Monterey, CA on December 10, 1941 and same-day delivery to the Navy Department - the exact 'Acquired Dec. 10, 1941' event the official Ships' Data table records for YP-385 (which it names 'Ex-Pacific Star'). The card records the 1941 takeover only; the 1945 Navy-to-WSA return transaction is not on this card, and the database fate field 'Returned - Foreign' is unexplained by any milestone. Linkage of this Pacific Star to YP-385 rests on three official records agreeing (Ships' Data 1943 ex-name; NARA SL-44 parenthetical; this card) - strong, but the card itself does not state a Navy designation. Handwritten card - 'Lonero' surname read with possible minor variance. Contains no asbestos information.

- Finding
- NARA Special List #44 (index by ship number to U.S. Navy deck logs 1801-1947 in the National Archives) indexes this hull's deck logs as 'YP-385 (Pacific Star)' in two ranges: 7/1/1942 - 5/31/1943 and 7/1/1943 - 4/30/1944. Deck logs are the official daily record of operations, movements, personnel, and material events; the index confirms logs exist for roughly the first 22 months of YP-385 service. No entry under AMc-147 - consistent with the AMc designation being an administrative label during the 1942 small-craft reclassification before logging began.

Coverage ends 4/30/1944; logs for May 1944 through the February 1945 WSA transfer are not indexed for this hull (separate accession or non-transfer unverified). The parenthetical 'Pacific Star' is NARA's vessel-name annotation for the numbered craft - it corroborates, but does not by itself prove, the commercial-vessel identity (the Ships' Data 1943 ex-name and MARAD card provide the identity chain). The digitized-logs catalog does not list YP-385 - these are physical-holdings entries, not online scans. Nothing in this row is an asbestos finding.

- Finding type
- asbestos_application
- Finding
- Design-level assessment of the asbestos-relevant profile: this craft carried a single diesel engine on one shaft in a ~71-ton, 81-ft wooden fishing-type hull - no boilers, no steam distribution system, no turbines (official Ships' Data 1943 'Diesel' entry; secondary spec blocks concur), and she was a converted commercial fishing vessel, not built to naval insulation specifications. The principal asbestos vectors documented aboard steam-era naval vessels - boiler and steam-drum lagging, steam-line insulation, turbine and condenser insulation - are absent by design in this type. Residual era-typical applications remain plausible but are undocumented for this hull: diesel exhaust and muffler insulation, engine gaskets and packing, electrical insulation, joiner materials, and brake linings on winch/windlass gear.

- Ship's company (unverified); construction trades at Martinac, 1940; conversion-yard workforce (unlocated)
- Limitations
- Design inference, not a ship-specific finding: the absence of a steam plant removes the dominant asbestos vectors but does not prove the absence of asbestos aboard - WWII-era gaskets, packing, electrical components, and interior materials could still contain asbestos, and whatever conversion/outfitting the Navy added in 1942 is undocumented. No located source names an asbestos product installed on this hull. Does not establish presence, absence, exposure, or causation for any individual.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII, the era in which this hull was built (1940) and taken into naval service (1941-1942); wartime demand drove unprecedented asbestos utilization aboard vessels including small auxiliary types.

- Publication-level discrepancies reconciled or logged: (a) Acquisition date - official Ships' Data 1943 records 'Acquired Dec. 10, 1941' and the MARAD status card documents the Dec. 10, 1941 2:00 P.M. requisition at Monterey; NavSource says 'acquired by the Navy in 1942' - the official date controls, with the 1942 reading consistent with paperwork formalization (sister YP-383's WSA bill of sale was formalized June 1942 after a Dec. 1941 takeover). (b) Original ownership - the shipbuildinghistory yard table's 'Original Owner: US Navy' cell is contradicted by the MARAD card showing private owner Sam Lonero at requisition. (c) Dimensions - official registered figures 81'3" x 23'6" control vs NavSource 81'/24' beam and yard-table 81'/71d; variance logged. (d) Disposal - 'WSA February 1945' (NavSource) vs 'to NDRF 1945' (yard table) vs 'returned' (official 1945 register) vs MARAD database fate 'Returned - Foreign' - a consistent disposal story with agency-label variance; 'Returned - Foreign' unexplained by any milestone. (e) Identity chain - fishing vessel Pacific Star -> AMc-147 -> YP-385 is established by three official records (Ships' Data 1943 ex-name; NARA SL-44 parenthetical; MARAD status card) that NavSource omits.
