- Finding
- The USCG Historian's Office documents this hull's pre-Navy identity: a 100-foot patrol boat built to combat rum-runners during Prohibition, one of 13 in her class; steel-hulled, capable of close inshore work, slower than the 75-foot patrol boats but with better accommodations for longer periods at sea; all 13 built by Defoe Boat & Motor Works, Bay City, Michigan. Patriot was stationed at Stapleton, New York initially, transferred to Fernandina, Florida in 1927, served out of Cleveland, Ohio as of 1933, and was placed out of service in 1938 (the file's own figure - DANFS and NavSource place the Navy transfer 24 August 1936; see gaps). File data: displacement 210 tons; length 99'8"; beam 23'; draft 4'6"; machinery 2 Grey Marine diesel engines, 300 BHP, twin propellers; speed 12 knots maximum; complement 15 (with 1 warrant officer); armament 1 x 3"/23 (1930). Disposition line reads 'Transferred to US Navy?' - the Historian's file hedges, while DANFS confirms the transfer.

[5]Shipbuilding History (Tim Colton's shipyard compilation), Defoe Shipbuilding yard table, Bay City MI - hulls 83-92 USCG 100-foot patrol boats; corroborating yard-tug table at shipbuildinghistory.com/smallships/yt1.htm [other_primary]

- The Defoe yard table identifies this hull's construction slot: yard hull no. 89, 'Patriot', US Coast Guard patrol craft, 210 dwt / 100 ft, delivered June 1926, disposition 'To USN 1936 as YT 127, YP 69 1938, sold 1946.' The same table documents that the Navy absorbed several sisters as yard patrol craft: Eagle (hull 83) to USN 1936 as YP-64; Gallatin (85) to USN 1934 as YP-42; Mahoning (86) to USN 1934 as YP-41; Naugatuck (88) to USN 1935 as YP-56; Perry (90) to USN 1937 (designation not recorded). The companion yard-tug table (yt1.htm) carries Patriot at YT-127 with the variant 'YP 69 1938, to NDRF 1947.'

- Shipscribe documents and captions a photograph of this hull: 'Patriot (YT-127) as YP-69 at Naval Air Station Pensacola circa 1941. The 99-foot vessel was acquired on 24 August 1936 and became YP-69 on 1 March 1938' - independently corroborating DANFS dates. The underlying photographic source is the NAS Pensacola/Jacksonville aviation-cadet yearbook 'The Flight Jacket' (1941 volume), held in NHHC's cruise-book/yearbook library collection (NHHC lists Flight Jacket for NAS Pensacola 1937, 1939, 1941-43 et seq.). The yearbook itself is the archival lead for her aviation-support service documentation.

[7]Era inference built on: USCG Historian's Office spec block (2 Grey Marine diesels, 300 BHP, twin propellers - no steam plant); NavSource specifications (identical machinery); DANFS vessel-type framing (tug / district patrol craft); Defoe yard table (1926 steel-hulled USCG patrol boat); GAO HRD-80-2 Navy-wide asbestos-use era (ev-07) [other_primary]

- asbestos_application
- Finding
- A steel-hulled diesel patrol craft built 1926 and run through 1946 sits inside the documented era of asbestos use in American marine construction and Navy practice (Navy-wide asbestos-insulation use ran through the early 1970s per GAO HRD-80-2). Era-standard asbestos applications aboard a small diesel vessel of this period were: exhaust-system lagging around diesel mufflers and piping; machinery, valve, and flange gaskets; packing; electrical insulation; and insulation/joiner material in machinery spaces and accommodations. As a diesel vessel with no steam plant, the boiler/turbine lagging pathway of steam ships does not apply - her asbestos-relevant footprint is correspondingly smaller than a steam vessel's, but gaskets, packing, and lagging remain plausible era-consistent applications.

Absence of a steam plant is documented (diesel machinery in both USCG and Navy records); any further inference would overreach the record.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming Patriot (YT-127), YP-69, or USCGC Patriot was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the fleet-wide pacing budget was exhausted each attempt (authenticated helper exit 2, 'pacing budget momentarily spent'); logged as blocked in search_ledger, not as a negative result. A targeted secondary-web sweep ('Patriot' 'YT-127' OR 'YP-69' asbestos) returned zero results - even law-firm listicles do not cover this hull.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era materials on a 1926 hull are consistent with asbestos-containing gaskets, packing, and lagging, and no survey ever checked. The litigation repository search is a genuine open gap (pacing-blocked, not run). USCG and Navy deck logs, Defoe construction records, and Maritime Commission disposal file for this hull are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- CORRECTION (name/prefix hygiene): 'USCGC Patriot (YT-127)' conflates two service prefixes. The hull was USCGC Patriot only during Coast Guard service (1926-36); in Navy service she was the district harbor tug Patriot (YT-127) (1936-38) and then district patrol craft YP-69 (1938-46) - in service, not commissioned, and no source located applies a USS prefix. Separately, 'Patriot' is a high-collision name: AG-58 (Patriot) was a distinct 1944 St. Louis Ship icebreaking tug lend-leased to the USSR in 1944; USS Patriot (PYc-47, ex-PC-455) was a 1930 Herreshoff yacht conversion; USS Patriot (MCM-7) is a 1991 Avenger-class mine countermeasures ship; and Patriot I was an 1861 schooner. None is this hull.
