    Limitations
    NavSource is a volunteer secondary compilation, not a primary registry; its decommissioning date (25 Mar 1946) conflicts with DANFS/shipscribe (26 Mar 1946) - see gaps. Its 'struck date unknown' is superseded by shipscribe's 5 Mar 1947. Launch-caption year '1944' on one photograph caption is a typographical error (launch was 19 July 1943).

    Finding
    The ship's muster-roll file is digitized and was examined. The first quarterly roll (NAVPERS 605 forwarding sheet, quarter ending 31 March 1944) is annotated '(Comm) 3-12-44 to 3-25-46 Decom' and was forwarded 5 April 1944 'From Atlantic Ship Yards, Boston, Mass.' - signed by J. A. Marston, Lt.(jg) USNR, Executive Officer, and approved by K. G. Cady, Lieut., USNR, Commanding Officer. The commissioning Report of Changes (NAVPERS 605-B) records the plankowner enlisted crew 'Received 12 March 1944' from 'Receiving Station, Bath, Maine' - named men with ratings (StM1c, BM1c, SM3c, S2c, EM2c, MoMM1c, RM2c, SF1c, Ck2c, Cox, MM1c, SoM2c, Y2c) enlisted at stations including Norfolk, Richmond, Houston, Chattanooga, New York, Raleigh, Albany, Providence, Bath, and Jacksonville. The final monthly Report of Changes (month ending 26 March 1946, received-stamped April 1946, signed R. G. Partridge, Lieut., USNR, Commanding) documents the end-of-service crew dispersal: bulk enlisted transfers 'Trans.' dated 3-25-46 to 'RecSta. San Pedro, Calif.' for discharge at the separation center nearest home address or 'for FURAS by COMWESTSEAFRON' - crew reduction concentrated on 25 March 1946, corroborating the 25 March decommissioning variant.

    A wooden-hulled diesel-electric net laying ship built 1942-44 sits inside the Navy's documented asbestos era. Era-standard small-ship applications aboard a vessel of this type and period: diesel-exhaust lagging, gaskets, valve packing, electrical insulation, deck coverings, and winch/boom brake linings - this hull's documented work was heavy net handling (12-ton boom; 'installation and maintenance of net defenses' at Eniwetok per her own war diaries). As a diesel-electric wooden ship she carried no steam plant and a smaller machinery footprint than steam-driven classes; the boiler/turbine lagging pathway does not apply.

CourtListener: exact-name opinion and docket searches both returned zero results; the "AN-61" hull-number opinion base query returned 110 hits, all 20 reviewed being name collisions (statute/docket-number strings, unrelated parties) with none ship- or asbestos-related; the authorized "AN-61" asbestos opinion variant returned 3 hits, all incidental string matches in unrelated cases (two asbestos product-liability cases where the string does not name this vessel, one contract dispute); the "AN-61" docket base query was deferred by fleet pacing during the session - see search_ledger for per-query status. Secondary web sweeps surfaced no asbestos claim naming this hull; the only tender-class asbestos content found is generic law-firm material that does not name the ship - excluded by source policy.

    Absence of a located public record does not prove absence of asbestos aboard - she was built and served wholly inside the Navy's documented asbestos era. Deck logs (inventoried Mar-Jun 1944 only, undigitized), Snow Shipyards construction records, and the 1950 buyer's identity are open leads. Does not establish or defeat any claim of exposure or legal eligibility.
