- Finding
- Katlian (YN-48), formerly the tug A. D. Canulette, was launched in 1939 by Canulette Shipbuilding Co., Slidell, La.; purchased by the Navy 1940-10-22 from Gulf Coast Towing Co.; and placed in service 1940-12-19. Following conversion at New Orleans she sailed 1940-12-31 for Mare Island, arriving 1941-03-07 via Guantanamo and the Canal Zone; assigned to the 12th Naval District and served as a net tender out of Mare Island throughout her naval service. Reclassified YNT-16 on 1942-05-01. Placed out of service 1946-01-30 and transferred to the Maritime Commission 1947-06-02; sold to R. J. Fenzl in 1948 and served as a tug named Captain Rudy, then A. D. Canulette, then Ethel McDermott. Spec block: dp. 129; l. 93'; b. 22'; dr. 8'; cl. Cockenoe.

DANFS's namesake description 'an Eskimo chief' is a period-era characterization - see correction row.

- Hull-specific chronology: YN-48 Katlian - acquired 1940-10-22, builder Canulette SB, completed 1939, placed in service 1940-12-19; out of service 1946-01-30, stricken 1946-02-26, disposed 1947-06-02 to Maritime Commission (MC), MC sale ca. Jun 1947. Ship note: 'Ex merc. A. D. CANULETTE. 129 tg, 93.0 x 22.0 x 8.0, 550 hp. Conversion by Naval Station New Orleans completed 19 Dec 40. To YNT-16 1 May 42. Merc. A. D. CANULETTE 1947 (?), CAPTAIN RUDY 1947, ETHEL McDERMOTT 1949.' Class notes: the 24 tugs of the YN 33-56 group were acquired per a CNO direction of 1940-07-03 under the District Craft Act of 26 Jun 1940; all were modern harbor tugs (built since 1935 or still building at end-1940); all except METACOM (YN-51) were diesel propelled, single screw; all 24 were reclassified YNT (Net Tender, Tug Class) on 1942-04-08 effective 1942-05-01; conversions were limited to fitting out with standard Navy items (no hull modifications required for net tending).

[5]Cross-source reconciliation of three discrepancies: namesake ethnicity, Fenzl transfer year, and power rating (sources: DANFS Katlian page; NavSource YNT-16 page; Ships' Data 1945 vol. III p.546; Shipscribe YN 33-56 page; NPS Sitka National Historical Park official park brochure text) [nps]

- DANFS Katlian page ('Eskimo chief', '1948'); NavSource 22048 (1947 registration, 550 hp); SDB1945v3 printed p.546 (1,100 shp); NPS sitk park-brochure.htm ('K'alyaan (Katlian)')
- Finding type
- historical_record
- Finding
- (a) Namesake: DANFS describes Katlian as 'an Eskimo chief of Sitka, Alaska, at the time of Russian colonization in 1804.' The National Park Service's Sitka National Historical Park materials identify the battle leader as 'K'alyaan (Katlian),' the Tlingit war chief who led Kiks.aadi clan warriors in the 1804 defense of Shis'gi Noow (Battle of Sitka); 'Eskimo' in DANFS is a period-era mischaracterization preserved verbatim in the official history. (b) Post-disposal transfer: DANFS says 'sold to R. J. Fenzl in 1948'; NavSource records 'Registered to R. J. Fenzl, Houston, TX, renamed Captain Rudy, 1947' and Shipscribe lists 'CAPTAIN RUDY 1947' - the 1947 registration/1948 sale framing is unresolved; both are reported. (c) Power: Ships' Data 1945 tabulates 1,100 shaft horsepower; NavSource and Shipscribe give 550 hp for the Atlas Imperial diesel - likely a rating-basis or transcription difference; unresolved.

- Correction row reconciling source conflicts; none of the discrepancies affects identity or the service timeline. The Tlingit/Kiks.aadi identification rests on NPS Sitka NHP materials (authoritative for the namesake's people and the 1804 battle); this row asserts the correction to the namesake description only, not any change to the DANFS service record. No asbestos content in any of these sources.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as an insulating and fireproofing material in U.S. shipbuilding and ship repair during World War II - the program era in which this 1939-built tug was acquired, converted at Naval Station New Orleans, and operated. Era context for the candidate material set aboard a small diesel auxiliary (thermal insulation, gaskets, packing, brake linings, electrical insulation); there is no boiler/steam-lagging pathway because the vessel was diesel-powered.

- Katlian's sole wartime duty station - Mare Island Navy Yard, 12th Naval District - is today a federal facility in the EPA Superfund program under state-lead cleanup (CA7170024775; not NPL-listed). The Navy's BRAC PMO documents that Mare Island reached peak shipbuilding, repair, overhaul, and maintenance capacity during WWII, the period of this vessel's net-tender service there.
