- Documented for this hull: ordered 25 Feb 1943; built by Gulfport Boiler & Welding (Port Arthur, TX); keel laid 24 Aug 1943; launched 25 Nov 1943; commissioned 23 Feb 1944; completed 18 Feb 1944 (bracketed class note); reclassified 'To ATA-172 15 May 44' (the class note for sister ATR-98 records the reclassification letter was promulgated 13 Apr 44 with 15 May 44 effective date); decommissioned 20 Feb 1947; stricken 23 Dec 1947; 'Transferred 20 Dec 47 to the Panama Canal Commission as TABOGA. Later DARYL C. HANNAH 1975, DARYL C 1983, CARL WILLIAM SELVICK 1988, ROSA M 1998 (based in Haiti and possibly renamed SALVAGE 1).' Class data: design Navy BAT-1; displacement 600 light / 835 max tons; 143.0' oa x 33.8' x 13.2'; armament 1-3"/50, 2-20mm; complement 43; 13 kts; 1 screw GM diesel-electric 1,500 HP. The class narrative documents that the Bureau of Ships contracted with General Motors for ATR 41-49 and 91-100, GM providing diesel engines and subcontractors building the hulls, and that VCNO directed construction of ATR 91-100 on 18 Jan 43.

Internal date discrepancy: disposition table shows decommission 20 Feb 47 and a '20 Feb 47' disposal entry, while the class note says transferred 20 Dec 47 and strike is 23 Dec 47 - the Feb disposal figure conflicts with the Dec transfer note (carried in gaps). Shipscribe is a researcher compilation from NARA records, not the registry itself; dates corroborated where possible against NavSource and BGSU federal documentation.

- NavSource is a volunteer secondary compilation, not a primary registry - its dates track shipscribe/NARA where overlapping. Contains no asbestos content. Two NavSource statements are contradicted by stronger sources: the 'Levingston Shipbuilding Co., Orange, TX' builder line (corrected to Gulfport Boiler & Welding - see ev-03) and the 'Commissioned USS ATA-172' styling (she commissioned as ATR-99; the ATA reclassification took effect 15 May 44 - see ev-01). Displacement figures (835 lt / 1,360 fl) conflict with class-standard 600 lt / 835 max - carried in gaps, not asserted.

[4]Builder-attribution cross-check: shipscribe ATR-41 construction table (ATR-99 = Gulfport Boiler & Welding); Gulfport yard hull list, hull 226 = 'ATR 99 / ATA 172'; BGSU HCGL federal-documentation record ('Builder: Gulfport Boiler and Welding Works, Inc., Port Arthur, TX'); Wikipedia Sotoyomo-class table (ATA-170..173 under Gulfport); vs NavSource/thamestugs 'Levingston Shipbuilding Co., Orange, TX' [other_primary]

- Finding type
- historical_record
- Finding
- CORRECTION: NavSource (and thamestugs following it) attributes this hull's construction to 'Levingston Shipbuilding Co., Orange, Texas.' Four independent records place the hull at Gulfport Boiler & Welding Works, Port Arthur, TX: (1) the shipscribe ATR-41-class construction table - compiled from NARA Bureau of Ships records - gives ATR-99 builder 'Gulfport Boiler & Welding' (the Levingston-built members of the order block are ATR 41-49 and 91-96; Gulfport built ATR-90 and 97-100); (2) the Gulfport yard's own hull list records hull no. 226 as 'ATR 99 / ATA 172' launched 25-Nov-43 'to Panama CC 1947 as Taboga'; (3) the federal vessel-documentation record abstracted by BGSU Historical Collections of the Great Lakes lists 'Gulfport Boiler and Welding Works, Inc., Port Arthur, TX, 1943'; (4) the Wikipedia class table groups ATA-170 through ATA-173 under Gulfport. NavSource/thamestugs' own detail 'YN226' matches Gulfport hull no. 226, not a Levingston number - the Levingston attribution is likely a propagated transcription error (Gulfport was acquired by Levingston Shipbuilding in 1970, a plausible source of later confusion).

The correction rests on convergence of the NARA-derived shipscribe table, the yard's hull list, the federal documentation record, and the class table - four concordant sources against NavSource's single line; the underlying NARA construction record itself was not pulled this session.

Registry trail: TABOGA (Panama Canal Zone registry, 1947-1971); TABOGA (U.S., official no. 545312, 1971-1975); HANNAH, DARYL C. (renamed June 1975); SELVICK, CARL WILLIAM; ROSA M (1998). 'First enrolled, May-June, 1973. (135.42 x 33.08 x 14.50; 473 gross - 149 net).' Casualty note: 'As HANNAH, DARYL C.; Two men were drowned when their 22-foot fishing boat was struck by the 143-foot tug. She had a barge in tow at the time and sounded a warning signal but the men in the fishing boat were unable to start the boats motor.' Disposition: 'Out of documentation.'

'First enrolled May-June 1973' postdates the 1971 Malcolm Marine sale - the hull's 1971-73 documentation status is unexplained (possibly foreign or undocumented interim; carried in gaps). Rename date June 1975 conflicts mildly with NavSource's 1974 sale to Hannah Marine - sale vs. documentation-rename dates differ. The drowning casualty is a safety event, not an exposure record.

Chronology largely agrees with shipscribe/NavSource: launched 25-11-1943; 'Delivered to US Navy as ATR-99' 23-2-1944; 'Reclassified Auxiliary Ocean Tug ATA-172' 1944; 'Deleted from Navy list' 1947; sold to Panama Canal Company, renamed Taboga; subsequent sales to Malcolm Marine (1971), Hannah Marine (1974, Daryl C. Hannah), Daryl C (1984), Selvick Marine (1988, Carl William Selvick), Roger Rouzier Jr. (8-1998, Rosa M), 'Later transferred to same owners Marintec Towing & Salvage Co., Port-au-Prince, Haiti.

- asbestos_application
- Finding
- A 143-ft steel-hulled diesel-electric ocean tug built 1943-44 inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation in a small confined hull volume. As a diesel-electric tug she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, but machinery-space and exhaust-system insulation plus era-standard gaskets/packing remain plausible installed materials for the type.

- Finding type

- Finding
- The canal authority's own occupational standard documents asbestos-bearing materials in its facilities and industrial shops and a formal substitution regime: 'Asbestos products such as ropes, fabric, linings, cement or dust, or products containing asbestos fibers may not be used to replace other products in work areas without written authorization'; substitution with non-asbestos materials required 'as soon as materials that do not contain asbestos become available to replace asbestos materials or asbestos bearing products currently in use.' The standard 'supersedes the policy and safety procedures in Chapter 790, Appendix E, of the former Panama Canal Commission Personnel Manual' - i.e., a formal asbestos-management regime existed inside the Panama Canal Commission system, the same federal agency that owned, operated, and maintained this hull as the tug Taboga from 1947 to 1971.

- Finding
- NAME COLLISION classification: the only federal appellate decision naming a vessel 'Taboga' connected to the Panama Canal is NOT this hull. In Tsakos, the M/t TABOGA - a motor tanker owned by Refineria Panama, S.A. - struck the stern of Tsakos's vessel IRENE'S GRACE in a Panama Canal lock while under Panama Canal Company pilotage; the appeal turned on Canal Zone Code waiver/sovereign-immunity mechanics. By the August 1978 district-court order this record's hull had already been renamed Daryl C. Hannah (June 1975, U.S. flag), was a 143-ft harbor/ocean tug rather than an 'M/t' motor tanker, and was never owned by Refineria Panama.
