- Finding
- NavSource's live YMS-123 page identifies the hull as a YMS-1-class auxiliary motor minesweeper, call sign Nan-Baker-King-How: laid down 2 July 1941 by the Krause and Banks Shipbuilding Co., Inc., North Bend, Oregon; launched 14 March 1942; completed 24 August 1942 and commissioned USS YMS-123; struck from the Naval Register 17 April 1946; transferred to the War Shipping Administration in February 1947; purchased by Nootka Sound Services Ltd. of Vancouver Island, British Columbia in late 1951 and placed in service as the passenger/cargo ship MV Uchuck III out of Gold River, BC. Specifications: 270 tons, 136 ft, 24 ft 6 in beam, 8 ft draft, 15 knots, complement 32, one 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; two 880-bhp GM 8-268A diesels on two shafts, engines replaced in 1951. The page displays NHHC photo NH 78179 (off Mare Island Navy Yard, 18 September 1942) and states no DANFS history is available for YMS-123.

- NavSource is a live secondary photo-archive compilation, not an official registry or primary construction/personnel record. Its 'Completed ... and commissioned' line is not an explicit commissioning instrument, the buyer name differs from the operator's own history page, and the page contains no asbestos, survey, abatement, product, exposure, or litigation evidence.

- Get West Adventure Cruises (Gold River, BC) publishes the history and current operation of the MV Uchuck III: a 'converted WW2 Minesweeper' originally 'built in Oregon as an American Yard Minesweeper in 1942'; purchased as a hull in late 1951; stripped of minesweeping equipment at a Vancouver dockyard after its 1948 arrival; converted 1951-1955 with components drawn from roughly twenty other vessels including two 500-hp 8-268A Cleveland diesel main engines from a U.S. Navy sub chaser; entered the Ucluelet run 1 August 1955; currently operating out of Gold River and described as 'celebrating 70 years of passenger and freight service' through Nootka Sound, Esperanza Inlet, and Kyuquot Sound.

- Limitations
- The operator page never prints 'YMS-123' - the YMS-123-to-Uchuck-III identity bridge rests on NavSource (ev-01), corroborated by the operator's Oregon-1942-YMS description and late-1951 purchase. The page contains no asbestos, survey, or materials information; 'totally refitted' conversion means original-era material condition cannot be inferred from this source.

- GAO's 1979 report HRD-80-2 reviewed the Navy's efforts to protect workers from asbestos exposure at Long Beach and Norfolk Naval Shipyards, including use of asbestos in Navy ships and the cost of removal, and describes the Navy's 1975 policy of replacing damaged or repair-affected asbestos insulation with nonasbestos material and its 1979 selective-replacement policy for high-maintenance areas.

- Limitations
- A failure to locate a public record is not proof that asbestos was absent. The NARA-indexed deck logs, the 184-image muster-roll file unit, and the war diary were not examined page-by-page; no class- or construction-era inference is used to claim asbestos was installed aboard this hull; and the 1951-1955 merchant refit further unsettles any assumption about retained original-era materials. This finding does not establish exposure, causation, or legal eligibility.
