- Documented for this hull (verbatim scope): 'Canotia (AN-47) was launched 4 July 1944 by Everett-Pacific Co., Everett, Wash.; sponsored by Mrs. F. Schmitz; commissioned 31 July 1944, Lieutenant Commander W. G. Holly, USNR, in command; and reported to the Pacific Fleet.' Departed San Francisco 6 October 1944 for Pearl Harbor (arrived 16 October); provided target service to ships training there until 5 February 1945; arrived Eniwetok 15 February, reported to the 5th Fleet, and sailed to Iwo Jima 'where she had mooring and salvage duty from 28 February to 12 April' - 'the first portion of this duty came as bitter action raged ashore, and enemy air attacks still menaced American shipping.' After routine repairs at Guam, arrived at Ulithi 14 June to install and maintain nets; after the Japanese surrender cruised the small islands of the western Carolines searching for American and Allied ex-prisoners of war or Japanese soldiers; received the surrender of the garrison on Lamotrek and destroyed a Japanese supply dump on Olimarao; between 23 September and 1 October removed net defenses at Ulithi and Kossol Roads; on 26 October cleared for San Diego 'where she was decommissioned 18 February 1946, and sold 21 April 1947.' 'Canotia received one battle star for World War II service.' Spec block: AN-47: dp. 1,100; l. 194'6"; b. 37'; dr. 13'6"; s. 12.1 k.; cpl. 56; a. 1 3"; cl. Ailanthus.

- Finding type
- historical_record
- Finding
- The official 1945 Navy Ships' Data table lists 'CANOTIA (ex-YN66)' under hull designation AN47, in the Everett-Pacific S.B. & D.D. Co., Everett, Wash., builder block, with fuel figure 760 (consistent with NavSource's 760 bbls diesel). This official wartime table, together with NavSource's timeline and the DANFS spec block, establishes the hull designation as AN-47 - correcting the NARA Special List 44 named-inventory misprint 'Canotia (AN-7)' (see ev-05; the real AN-7 was USS Ash, an unrelated Aloe-class tender).

- Finding
- NARA's deck-log inventory lists one logbook run for this hull under the misprinted designation 'Canotia (AN-7)': coverage 7/31/1944 - 6/30/1945. The opening date coincides exactly with her 31 July 1944 commissioning, confirming the log is Canotia's despite the printed hull number. The companion ship-number PDF index (sl-44-ship-number.pdf) contains no AN-47, YN-66, or AN-7 entry for this hull - the named list is the sole NARA inventory entry. The logs are physical holdings of RG 24 Entry 118 at Archives II, College Park, not digitized in the National Archives Catalog for this hull.

- Finding
- Class context: the U.S. Navy ordered 77 new-construction ships in three similar classes as net tenders, initially in the YN hull-number series, then redesignated AN and renumbered in January 1944; ships wore paired bow 'horns' supporting running rigging for maneuvering float-supported steel antisubmarine nets, with winches fore and aft making them valuable as salvage ships and tugs. Of Canotia's own class: 'The 30 wooden-construction net tenders of the 1942 program Ailanthus (AN-38-77) class were far larger than the Aloes, displacing up to 1,400 tons full load and being nearly 195 feet long'; all three classes had single-screw, diesel-electric propulsion plants.

- Finding
- A wooden-hulled diesel-electric net laying ship built February-July 1944 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were diesel-exhaust and machinery lagging, gaskets, valve packing, electrical insulation, accommodation insulation in the wood-hulled interior, and brake linings on the net-handling winches and windlass. As a diesel-electric ship she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.
