- NavSource Mine Warfare Vessel Photo Archive entry for YP-387 ex-AMc-200: built 1941 at Bethlehem Steel, Quincy MA for R. O'Brien and Co., delivered 1941-11-06; acquired by the Navy in 1942 and designated coastal minesweeper AMc-200; converged on the torpedoed tanker R.P. Resor off Sea Girt and searched for survivors (February 1942); reclassified district patrol craft YP-387 and placed in service May 1942; collided with collier SS Jason (ex-AV-2, ex-AC-12) and sank 1942-05-20 approximately 7.5 miles NNE of Wildwood, NJ; wreck located 1947 and demolished as a hazard to navigation. Specs given: 301 t displacement, 110 ft, 22 ft beam, one diesel engine, one shaft.

- Limitations
- NavSource is a curated secondary archive of official records, not itself a primary source; it explicitly notes no DANFS history exists for YP-387. Key facts corroborated independently: identity/build via the Bethlehem Quincy builder table, loss via the CNO's official loss appendix, demolition via DANFS Windlass. NavSource writes 'Sea Girt, DE' - Sea Girt is in New Jersey and the cited position (39 47N 73 26W) is off the NJ coast; it also dates the Resor torpedoing 26 Feb where uboat.net's war-diary account gives 27 Feb. Tonnage/length figures differ from the builder's table (301 t/110 ft vs 170 GT/102 ft). No asbestos information.

- Finding
- Bethlehem Quincy (Fore River) builder's table records hull 1514 as the trawler Salem, U.S. Official No. 241144, 170 GT, 102 ft, owner R. O'Brien & Co., delivered 1941-11-06 - matching NavSource's delivery date for AMc-200/YP-387 and fixing the hull's pre-Navy identity. Sister hulls in the same table: 1512 Cohasset (ON 24078, del. 1941-10-09, 'To USN 1942 as AMC 202, YP 389') and 1513 Lynn (ON 241106, del. 1941-10-22, 'To USN 1942 as AMC 201, YP 388, sold 1946 as Lynn, in collision and sank 1951'); 1515 Weymouth disposition blank.

- Shipbuilding-reference compilation of builder/registry data, not a government record; independent corroboration of NavSource's build/delivery details and the Salem identity. Salem's own disposition cell is blank in the table - the AMc-200/YP-387 linkage rests on the identical delivery date (1941-11-06) across the two sources plus secondary dive-site naming. Contains no asbestos information.

- Finding
- DANFS records the postwar disposition of the wreck: on 1947-09-10 USS Windlass (ARS(D)-4), with sister Salvager (ARS(D)-3), began searching for the sunken YP-387, located it off Hereford, NJ, and on 1947-10-03 the two salvage vessels placed demolition charges in the hull and blew it up 'to prevent her from being a hazard to navigation.' The DANFS patrol-vessels appendix separately records 'YP-387 sunk by collision, 20 May 1942.'

- Finding
- In late February 1942 the tanker R.P. Resor was torpedoed by U-578 off the New Jersey coast at 39 47N, 73 26W (east of Manasquan Inlet); of her complement of 50, two survivors were picked up by USCGC CG-4344 and 48 died; the burning tanker sank nearly 48 hours later about 31 miles east of Barnegat, NJ. NavSource records that AMc-200 converged on the scene and searched for survivors - the vessel's documented February 1942 rescue-search operation.

- Limitations
- uboat.net corroborates the event (torpedo hit 06.36 on 1942-02-27, position, casualties) but does not name AMc-200; the craft's participation rests on NavSource alone, which dates the torpedoing 1942-02-26 - one day earlier than the war-diary-based 27 Feb. Reputable specialist databases, not primary documents. No asbestos information.

- Finding type
- asbestos_application
- Finding
- Peer-reviewed scholarship documents extensive asbestos use as fireproofing and insulation in U.S. ship construction and repair during WWII - the era in which this vessel was built (1941) and converted (1942). For this 170-GT diesel-driven trawler the era-consistent application set is narrower than for steam combatants: no boilers or steam lines, so plausible applications are confined to machinery/exhaust insulation, gaskets, packing, electrical insulation, and deck or house materials.

- Limitations
- Era/program-level scholarship; does not name this vessel, this type, or any small diesel craft and does not establish that asbestos was or remains aboard this hull. The narrowing to non-steam applications is analytical context from the documented propulsion plant, not a documented material finding. Does not establish quantity, location, exposure, or causation.

- Finding
- The builder yard is a documented asbestos-litigation site in the companion shipyard dataset: a federal court record states a plaintiff worked as a pipefitter's/drafting apprentice at Fore River Shipyard, Quincy MA, 1967-1970 and sued over asbestos-related disease (Oliver v. General Electric Co. et al., D. Md. No. 1:16-cv-01057); the yard entry's documented products include boilers, pipes, turbines, fireproofing materials, gaskets, packing, and electrical components.

- Population
- Fore River Shipyard workers (yard-level, 1967-1970 period in cited case)
- Limitations
- Builder-yard context only - the documented exposure period (1967-1970) postdates this hull's 1941 construction by 26 years and concerns the yard, not this vessel. Establishes that the builder's operation is a known asbestos site; establishes nothing about materials aboard hull 1514. Does not support any 'documented aboard' wording.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement record, hazmat disclosure, or docketed asbestos case naming YP-387, AMc-200, or the trawler Salem was found in the public sources searched. CourtListener returned zero opinions for 'YP-387', 'AMc-200', and 'AMC-200'; zero dockets for 'YP-387'; 15 docket hits for 'AMc-200' are all name collisions (bankruptcy docket-number initials 'amc', AMC Entertainment securities litigation). No DANFS entry exists for the hull. The vessel sank in May 1942 - before the asbestos-litigation era - and six deaths in the sinking are reported only by secondary wreck references.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-consistent gasket, packing, and insulation materials may have been present and are unproven either way. The 1942 loss and 1947 in-place demolition mean no intact hull survives to survey. Does not establish or defeat any claim of exposure or legal eligibility.
