- DANFS (NHHC, updated 2023-11-21 by Robert J. Cressman): IX-85 - tonnage 59 (gross register); length 85'0" overall / 66'8" waterline; beam 20'0"; draft 6'6" mean; complement 15. The wooden-hulled yawl Nurmah, built 1910 at Neponset, Mass., by George A. Lawley & Sons, was renamed Mayhap. The Navy acquired Mayhap from John N. Matthews of New York in 1942; allocated to the Seventh Naval District, renamed Euhaw, designated unclassified vessel IX-85. Crew drawn from the Section Base at Port Everglades, Fla.; placed in service 13 October 1942, Lt. Cmdr. Arnold W. Chapin, D-V(S), USNR, officer-in-charge. Taken out of service 15 March 1943, crew returned to the Section Base; stricken from the Navy Register 28 June 1944 and transferred to the War Shipping Administration for disposal. John Matthews bought his craft in November 1944 and she resumed service as Mayhap; in 1958 Mayhap came under British registry.

- Volunteer-compiled archive reproducing register data - several figures differ from DANFS (see correction row); used for construction/conversion detail and the merchant-registry trail only. Contains no asbestos information; supports no asbestos claim. The 'placed out of service June 1944' entry conflicts with DANFS (15 March 1943) and is not adopted.

[4]NHHC DANFS (controlling) vs NavSource IX-85 archive page and shipbuildinghistory Lawley table [nhhc_danfs]
- Locator
- Cross-comparison of DANFS text/parenthetical vs NavSource characteristics block
- Finding type
- vessel_history
- Finding
- Source discrepancies resolved: (a) out-of-service date - NavSource lists 'placed out of service, in June 1944,' while DANFS (NHHC, updated 2023) states 'taken out of service on 15 March 1943'; the DANFS date is adopted as controlling (NavSource's June 1944 may conflate the stricken date of 28 June 1944 with an administrative status change). (b) Builder styling - DANFS writes 'George A. Lawley & Sons,' NavSource 'George S. Lawley & Sons,' while institutional sources (MIT Museum, Dorchester Atheneum) style the Neponset firm 'George Lawley & Son(s)'; the DANFS wording is carried in the builder field and all variants noted here. (c) Complement - DANFS parenthetical gives 15, NavSource gives 10 (1944); both carried. (d) Dimensions - DANFS 85'0" oa / 20'0" beam / 6'6" mean draft vs NavSource 84' oa / 19' beam / 5'8" draft; DANFS register figures adopted in prose.

- asbestos_application
- Finding
- Era context only: peer-reviewed scholarship documents extensive asbestos use as a fireproofing and insulating material in U.S. ship construction and repair during WWII - the era of this vessel's 1942 naval conversion (completed September 1942). The documentation covers production-scale shipyard work, not private yacht conversions at a Section Base, and does not name this hull.

- Limitations
- Program/era-level context for WWII shipbuilding generally. This vessel is a wooden sailing yawl with a small auxiliary engine and no steam plant - the mass-production shipyard exposure picture does not transfer; whether the 1942 conversion introduced any asbestos-containing material aboard this hull is undocumented.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or indexed-opinion litigation naming Euhaw/IX-85/Nurmah/Mayhap was found in the public sources searched - DANFS and NavSource contain no asbestos or insulation-material statement; the Naval Vessel Register excludes pre-1987 disposals; MARAD ShipHistory returns no vessel under any of the four names; no museum holds the vessel (fate unknown after 1958 British-registry transfer).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-typical components (engine-exhaust lagging, gaskets, electrical insulation) could have been present and are simply undocumented for this hull. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.
