- NHHC records: 'Aide De Camp, a wooden-hulled motor yacht designed by B. T. Dobson, was built in 1922 at Neponset, Mass., by the George Lawley & Sons Corporation for the noted yarn manufacturer, Samuel Agar Salvage, whom she served as Colleen.' Spec block: dp. 167; l. 110'; b. 18'2"; dr. 6'; s. 15.0 k. Ownership chain: John Gilbert Winant bought her from Karl W. Erikon of New York City in late 1926 or early 1927 and renamed her Ranger; about a year later H. M. Pierce of Red Lion, Del., renamed her Poinsettia; in 1931 Boston financier Frederick Henry Prince renamed her Aide de Camp, a name she bore under Frank D. Comerford and Harvard University. Early in WWII she was turned over to Harvard's Underwater Sound Laboratory for experimental sonar/antisubmarine-warfare work, then passed to OSRD custody ('the records of the transfer have apparently perished'). Transferred to the Navy 31 May 1945; placed in service 18 Jun 1945, Lt. David W. Warren, Jr., in charge; assigned to Commander, 7th Naval District for Bureau of Ordnance underwater sound research based at Fort Lauderdale, Fla.; placed out of service 2 Nov 1945; stricken 28 Nov 1945; transferred to the Maritime Administration 4 Sep 1946 and sold. Post-Navy: Gustave G. Copeland of Miami 1949; Fred Bowman of DeLand 1951; home port Pensacola 1953; ca. 1955 Kennedy Marine Engine Co., commercial operations from Biloxi, Miss., as Mariner 11; remained in that status into the 1980s.

- Compilation naming this hull in construction/disposition tables and a dedicated ship note: IX-224 AIDE DE CAMP - 'Ex yacht AIDE DE CAMP, previously named POINSETTA, RANGER, and originally COLLEEN. Motor yacht. 167 tons full load, 113 tons gross. 110.0' oa, 102.0' wl x 18.2' x 6.0'. Wood hull. 2 Winton diesels (fitted 1929), 400 HP, 15.0 kts. Sold in September 1946 to Evald Sooder of Miami, Fla., the yacht AIDE DE CAMP was listed in U.S. merchant vessel registers as being owned by the President and Fellows of Harvard College until she was transferred to U.S. Government ownership in 1948. In around 1955 she became MARINER II, owned by the Kennedy Marine Engine Co. of Biloxi, Miss., and was still in service for that firm in 1972.' Class note documents the acquisition machinery: 27 Apr 1945 Bureau of Ordnance requested transfer of the yacht and the 30-foot motor boat TOMMY from OSRD for BuOrd underwater sound research at Fort Lauderdale; owner in 1942 was Frank D. Comerford of Boston; by 1945 both craft were OSRD-owned and operated by Harvard's Underwater Sound Laboratory; HUSL functions were to pass to Pennsylvania State College on 1 Aug 1945 and that college declined responsibility for the craft; the District Craft Development Board on 9 May 1945 recommended Navy transfer to Comdt. 7th Naval District for BuOrd use at Fort Lauderdale, with IX classification for AIDE DE CAMP, citing the impracticability of transferring the installed research equipment to a service-designed vessel.

- Scholarly/institutional record of the organization that operated this vessel 1942-1945: Harvard Underwater Sound Laboratory ran sonar and acoustic-homing-torpedo R&D under NDRC Division 6 / OSRD contracts OEMsr-58 and OEMsr-287 (director Frederick V. Hunt, who coined 'sonar'); founded June 1941, closed 31 Jan 1946; its torpedo division became Penn State's Ordnance Research Laboratory (now Applied Research Laboratory) in 1945 - the same Penn State transfer that prompted the Navy to take custody of this vessel and her installed research equipment rather than move the equipment.

[7]Consolidated era/design inference - shipscribe IX-224 ship note (documented machinery: wood hull, 2 Winton diesels fitted 1929, 400 hp) + WWII-era asbestos-use scholarship (Corn & Starr 1987; Fleischer et al. 1946) [other_primary]

- Finding type
- asbestos_application
- Finding
- Era/design inference, deliberately narrowed: this hull is documented as a wooden-hulled motor yacht powered by two Winton diesels (fitted 1929) - there is no boiler or steam plant, so the asbestos-containing boiler insulation and steam-line lagging pathway documented for WWII steam auxiliaries does not apply to this hull's machinery. The residual era-typical applications for a 1922 diesel motor yacht are engine/exhaust insulation (exhaust line and muffler lagging), engine gaskets and machinery packing, electrical wiring and switchboard insulation, and asbestos-cement sheet/joiner work in accommodation spaces. Documented disturbance events for this hull - the 1929 diesel repowering, WWII laboratory outfitting with sonar-research equipment, the Jun-Nov 1945 Navy period, and post-1946 yacht/commercial conversions (as Mariner II into the 1980s) - are disturbance-phase pathways whose materials scope is unrecorded.

- Limitations
- Inference from the documented machinery type and construction era - NOT a hull record. No survey, specification, contract, or material schedule naming IX-224 or any of her yacht names was located; establishes no asbestos content, quantity, location, individual exposure, or causation. The inference is materially weaker for this hull than for steam auxiliaries because its documented plant excludes the steam-lagging pathway.

- Finding type
- asbestos_application
- Finding
- Era literature documents extensive asbestos use as fireproofing and insulation in U.S. WWII shipbuilding generally (Corn & Starr 1987) and amosite as 'an important ingredient of pipe covering material used on U.S. Navy vessels' in the USMC-commissioned 1944-45 industrial-hygiene survey (Fleischer et al. 1946). For this hull the relevance is indirect: the documented plant is twin Winton diesels with no steam system, so the pipe-covering/steam-lagging findings of these sources do not map onto this vessel's machinery - retained as era context only.

CourtListener hits are name collisions - 'aide de camp' as the military staff title (7 opinion hits incl. 19th-century and military-civil cases; 92 docket hits in trademark/criminal/FOIA/FSIA filings sampled) and 'IX-224' as an exhibit/identifier string in Delaware corporate opinions (2 hits) - not this hull. One law-firm marketing list page names the hull (freeasbestostesting.com auxiliary-ships list) asserting era-typical content without primary support - excluded source class, logged in batch report.

- Absence of a located public record does not prove absence of asbestos aboard - a 1922 motor yacht's exhaust lagging, gaskets, wiring insulation, and joiner work are era-consistent with asbestos-containing materials, and her documented repowerings/outfittings are unrecorded disturbance phases. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility. CourtListener docket-level recall is phrase-matched; the 92-hit set was sampled (top 15 by relevance) and all inspected hits were job-title collisions - uninspected tail cannot be certified collision-free.
