The page's specification block lists: displacement 270 t., length 136 ft, beam 24 ft 6 in, draft 8 ft, speed 15 kts, complement 32, armament one 3"/50 dual purpose gun mount, two 20mm mounts, and two depth charge projectors, and propulsion two 880 bhp General Motors 8-268A diesel engines with Snow and Knobstedt single reduction gear on two shafts. Call sign Nan-Able-Nan-Yoke. The page states: 'There is no DANFS history available for YMS-108', shows no commanding-officer table, and carries 'No image of YMS-108 is available at this time.'

   Limitations

   NavSource is a live secondary photo-archive compilation, not an official registry. Its builder line reads 'Burger Boat Co., Boothbay Harbor, ME' - the city is contradicted by uboat.net, Naval Marine Archive, Shipbuilding History, and the Wisconsin Maritime Museum's own launch-party record, all of which place Burger Boat at Manitowoc, Wisconsin (the adjacent Frank L. Sample hulls YMS-104/105/106 were the Boothbay Harbor-built boats; the error likely transposed the neighboring yard's location). It styles 24 August 1942 'Completed' rather than 'Commissioned', and its spec block conflicts with its own class-index figures (270 t vs 320 t; 15 kts vs 12 kts designed; 32 vs 33 complement; 8 ft vs 6 ft 1 in draft). It contains no asbestos, survey, abatement, product, or exposure evidence.

The same table shows the neighboring hulls YMS-104, YMS-105, and YMS-106 were built by Frank L.

The description records that the woman holding the bouquet is Mrs. Henry Burger, the sponsor, and that a note penciled on the photo's back states her bottle failed to break when she struck the vessel, so Mrs. G.

   Finding type

   Finding

   NavSource's Auxiliary Motor Minesweeper index establishes the class context and this hull's place in it: the Henry B. Nevins, Inc. Shipyard at City Island designed the type and laid YMS-1's keel on 4 March 1941 as the first United States 'Yard class Minesweeper'; 561 hulls of the wooden type were built at 35 yacht yards (12 East Coast, 19 West Coast, four Great Lakes); all 481 U.S. ships of the type shared the same general characteristics; YMS-1 through 134 had two stacks (the first/Mk I appearance group, which includes this hull); originally rated as service craft, they did WWII inshore sweeping ahead of amphibious assaults; survivors were reclassified AMS and given names in 1947, became MSC(O) in 1955 and MSCO in 1967; Ruff (MSCO-54, ex-YMS-327), last of the type in U.S. service, was struck November 1969. In the index's hull list, YMS-108 appears as a bare entry with no 'Named/Reclassified' annotation - unlike adjacent YMS-109 ('Brambling (AMS 42)'), YMS-113 ('Brant (AMS 43)'), and YMS-114 ('Courlan (AMS 44)') - consistent with her 3 July 1946 striking predating the 1947 reclassification.

The bare-entry observation supports but does not by itself prove the absence of any reclassification (the striking date does that). No asbestos, material, or exposure content.

NARA also notes that only some Navy records have been digitized and many remain in paper or microfilm.
