- NavSource chronology: originally planned as Coastal Minesweeper AMc-174; laid down 1942-04-14 at Henry G. Marr Boatbuilding Co., Damariscotta, ME; launched 1942-08-08; commissioned USS APc-13 on 1942-12-07 with LTjg Ogden Knapp, USNR, in command. Asiatic-Pacific Theater service: Bismarck Archipelago operation (Cape Gloucester, New Britain, 1944-02-03 to 1944-02-05) and Luzon operation (Lingayen Gulf landings, 1945-01-04 to 1945-01-18); two battle stars for WWII service. Decommissioned 1946-02-19 at Seattle, WA; struck from the Naval Register 1946-03-12; transferred to the Maritime Administration (sic - Maritime Commission) 1947; sold 1948-05-18 to Raymond G. Turner, San Diego, CA; fate unknown. Spec block: 100 t light / 258 t full; 103'3" x 21'3" x 9'3"; 10 kts; 3 officers + 22 enlisted; troop capacity 66; four single 20mm AA mounts; one General Motors 8-268A diesel, 400 shp, single screw, two 30 kW diesel ship's-service generators. CO list: Knapp to 1944-09-25; MacDougall to 1945-01-15; Franatis to 1945-12-06; Tinker to 1946-02-19. Page states explicitly: 'There is no DANFS history record for USS APc-13 available.'

- Limitations
- Volunteer archival compilation, not an official record - establishes identity, service history, and specification only as compiled from contributor material. Commissioning date conflicts with the 1942-12-09 date given by the NARA deck-log index, shipscribe, NavalCoverMuseum, and the builder's delivery table (see ev-02, ev-04, ev-05). 'Maritime Administration (MARAD) in 1947' is anachronistic - the Maritime Commission administered disposal; MARAD was created 1950. Contains no asbestos or materials information.

- Finding
- The NARA finding aid indexes a deck-log series for APC-13 spanning 12/9/1942 to 2/19/1946 - matching the documented commissioning-to-decommissioning interval exactly and corroborating 9 December 1942 (not NavSource's 7 December) as the start of the commissioned log run.

- Limitations
- Finding aid documents the existence and date span of the log series, not log contents - the logs themselves were not retrieved and their digitization status was not verified. Supports the 9 December 1942 commissioning date but does not by itself prove the commissioning ceremony date (a log series can begin on a delivery or in-service date). Contains no asbestos or materials information.

- Finding
- Designation correction: AMc-174 was a planned coastal-minesweeper designation only and no minesweeper ever served under it. The 50 hulls ordered as AMc-150-199 were redirected to completion as small coastal transports after the CNO's 1942-04-13 request for 'raider transports, AP'; the 'Coastal transport (small), APc' category was created 1942-04-22 and AMc 150-199 became APc 1-50 (not respectively). This hull commissioned as USS APc-13; the canonical record is APc-13 with AMc-174 as a consolidation alias.

- Redesignation documented by secondary compilations (NavSource index 'APc-13 ex AMc-174'; shipscribe class notes; Wikipedia roster) - the underlying CNO directive and BuShips correspondence were not directly retrieved. Hull-number collision note: NavSource /11/05174.htm is MSC-174 (Dutch-built MSC-172-class minesweeper Roermond, M 806), an unrelated vessel sharing only the numeral.

- Class configuration: APc-1-class small coastal transports were wooden-hulled craft of 161 tons light / 258 tons limited, 103.25 ft overall x 21.25 ft x 9.25 ft, 10 knots, single-screw diesel of 400 hp, original armament four single 20mm, complement 21 (1944 figure). Procurement history: AMc 150-199 ordered per CNO directive of 1942-01-19; BuShips issued modified-design specifications February 1942; CNO requested completion as raider transports 1942-04-13; District Craft Development Board recommended the change 1942-04-20 and the APc category was created 1942-04-22 for uses including 24-hour transport of a raiding party, troop-plus-cargo lift, and a 2,500-mile cargo run. Construction-table row for APc-13: ordered 1942-02-19, builder Harry G. Marr, keel 1942-04-14, launched 1942-08-08, commissioned 1942-12-09.

- Class-level specification and NVR-derived compilation; documents the type's plant and the class procurement history, not materials aboard this hull. Absence of a steam plant removes the most commonly documented WWII asbestos pathway but does not establish that no asbestos-containing material was aboard (gaskets, exhaust insulation, electrical insulation, fireproofing compounds remain undocumented either way). Complement figure conflicts with NavSource's 25. No asbestos or materials information.

Marr, Damariscotta ME, 100 LDT, 103 LOA, 1942, To MARAD 1947.' Yard history: founded by Jonah P. Morse in 1919, turned over to Harry G. Marr in 1939; located in downtown Damariscotta where the municipal parking lot now stands. The yard also built sisters AMc-175/APc-14 and APc-55 through APc-57, and the AMc minesweepers Security (AMc-103) and Skipper (AMc-104).

- 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 context in which this 1942 wooden-hulled transport was built - and that wartime demand drove unprecedented asbestos utilization across naval construction.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming APc-13, AMc-174, or USS APc-13 was found in the public sources searched (see search_ledger). No DANFS entry exists for this unnamed hull. Web-level litigation search returned only ship-list pages and unrelated litigation.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - it reports that no qualifying record was found. The CourtListener opinion/RECAP name search was blocked by quota exhaustion at query time (authenticated 2,800/day already consumed; expected reset ~4,600 s), so the litigation sweep is incomplete and flagged rather than failed silently. Does not establish or defeat any claim of exposure or legal eligibility.

Turner and could fix the 1947-vs-1948 date; USCG Merchant Vessels of the United States annuals are the verification path for any post-1948 civilian documentation (official number, owners, disposition - 'fate unknown' per NavSource); NavSource holds a contributed photo of APc-13 moored pierside (contributed by Brandon Cooper for his grandfather Roy Dale Cooper Sr., MoMM2/c, USS APc-13).
