- Shipscribe (Stephen S. Roberts) compilation of BuShips/NARA correspondence for IX-80: on 4 Jul 1942 the Gulf Sea Frontier requested authority to purchase the motor vessel Christiana for conversion to a seaplane tender operating OS2U-type seaplanes in ASW; on 6 Jul 1942 VCNO directed BuShips to negotiate purchase from owners Bahamas Trading Co. (foreign registry); acquired 6 Aug 1942; assigned as IX-80 to the Gulf Sea Frontier 22 Aug 1942; converted by Tampa Shipbuilding Co. between 23 Aug and 21 Nov 1942; reassigned to 7th Naval District 5 Nov 1943; reclassified YAG-32 20 Nov 1943; supported seaplane patrols in the Caribbean to May 1945, usually from an anchorage near Royal Island, Bahamas; name cancelled 1 Mar 1945 per CNO policy that most YAGs were unnamed; sold February 1946 to S. E. Thatcher of Miami. Ship note: ex-merchant Christiana, ex-Azalea (USLS); 393 tons light / 640 tons full load; 154 ft oa x 24.25 ft x 12.3 ft; iron hull; 1 Cooper Bessemer diesel; originally had a 400 HP inverted condensing compound steam engine and one single-ended Scotch boiler, probably converted to diesel during a second major repair period in 1941; repaired after a 1921 collision; decommissioned from Lighthouse Service 30 Jun 1933 and sold.

- Finding type
- asbestos_application
- Finding
- Era-level asbestos context only. (a) The hull's original 1891 steam plant (one single-ended Scotch boiler, 400-hp inverted-condensing compound engine) belongs to the era in which marine boiler and steam-pipe insulation, gaskets, and packing commonly contained asbestos; BuShips SDB-1945 records rebuilds in 1920 and 1941 and the plant was probably replaced by diesel before Navy acquisition. (b) Her August-November 1942 conversion to a seaplane tender at Tampa Shipbuilding Co. (Tampa FL) and her 1942-45 Navy service fall squarely in the peak wartime asbestos-use era of U.S. shipbuilding and repair, when exhaust/engine-room lagging, gaskets, packing, accommodation insulation, and winch brake linings were commonly asbestos-containing. Peer-reviewed scholarship documents extensive required asbestos use in WWII-era U.S. shipbuilding generally.

- Limitations
- Program/era-level documentation - does not name this hull. The steam plant (principal asbestos-bearing system of a vessel this size) was probably removed in 1941 before Navy acquisition, so the WWII-service asbestos surface is plausibly smaller than a steam auxiliary's - still inference, not record. No survey, invoice, or material list for this hull was located.

Marine Transport Lines, Inc., 723 F. Supp. 1126 (D. Md. 1989), a seaman's asbestos unseaworthiness suit against a commercial fleet operator, matching incidentally on the Azalea name (in context, a different vessel or fleet reference; no relation to this hull). No qualifying asbestos litigation naming USS Christiana, IX-80, YAG-32, or this hull's other identities was located.

- Limitations
- Opinion-index sweep only; RECAP/docket-type queries were fleet-rate-limit paced at research time (logged in search_ledger). The single 'Azalea' hit (Vaughn v. Marine Transport Lines) could not be full-text confirmed - CourtListener opinion pages do not render body text to plain fetches - but its defendant and posture (seaman v. commercial fleet operator) bear no relation to this hull and it is classified as a name collision. Complaints that name vessels only in unindexed pleading lists, and suits against the vessel's private owners (Bahamas Trading Co., S. E. Thatcher), may exist outside the opinion index. A negative opinion-index result is not proof that no claim was ever filed.
