- Documented for this hull (live NHHC DANFS): 'An island at the head of Blue Hill Bay, Maine, across from Mount Desert Island.' Spec block: 'displacement 167; length 117'; beam 24'; draft 8'9"; speed 9 knots.' 'The wooden steam ferryboat Aucocisco was built in 1897 at South Portland, Maine, by South Portland Shipbuilding Co., and was acquired on 3 April 1942 from Casco Bay Lines, Inc., of Portland. She was placed in service in the First Naval District on 5 May 1942 at Portland, designated as a ferryboat, YFB-32, and renamed Green Island.' 'Used to transport fleet liberty parties in Casco Bay, Maine, Green Island continued in service until returned to her former owner on 18 December 1945. Her name was stricken from the Navy Register on 20 March 1946. She continued to serve as Aucocisco until 1952-1953.'

- NavSource timeline for this hull: 'Wooden hulled Ferry Boat. Built by Portland Shipbuilding Co., South Portland, ME (also known as Nathan Dyer's Yard). Launched, 03 May 1897. Completed for Harpswell Steamboat Co., Portland, ME as Aucocisco (ON 107286), 1897. Consolidated into Casco Bay and Harpswell Steamboat Company, 1907. Company reorganized as Casco Bay Lines by winter 1919. Acquired by the US Navy, 03 April 1942. Placed in service as Green Island (YFB-32), 05 May 1942. Allocated to the 1st Naval District, used, along with YAG-12 as liberty boat at Casco Bay, ME, 1942-45. Placed out of service, date unknown. Returned to Casco Bay Lines, Inc., 18 December 1945. Struck from the Naval Register, 20 March 1946. Returned to Casco Bay Lines and resumed operations as Aucocisco, 1946. Placed out of service, 1952. Final Disposition, scrapped 1954.' Specifications: 167 gross tons; 117' x 24' x 8'9"; speed listed '0 kts' (spec-block error - DANFS gives 9); complement 'unknown'; armament 'none'; propulsion 'one compound 2-cylinder steam engine (15" 30" x 18"), single propeller, 250shp.'

- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track NVR/DANFS but the builder attribution differs from DANFS ('Portland Shipbuilding Co.' vs 'South Portland Shipbuilding Co.'; resolved as the same Ferry Village yard in ev-06) and its spec-block speed ('0 kts') is an obvious data error. Contains no asbestos content. The 1954 scrapping predates modern ACM-handling regulation; no hazmat or material record for the breakup was located.

- NHF Part IV, ferryboat passage and liberty-port paragraph
- Finding type
- historical_record
- Finding
- The NHF operational history describes this hull's wartime employment: 'During WWII, she served as a ferryboat based in Portland to and from naval vessels moored or anchored out in the bay. Along with its sister vessel the Penobscot Bay steamer North Haven (YAG 12), Green Island served as a large "liberty boats". A trip down the bay covered distances up to six miles from Portland and included multiple stops, often under unpleasant weather conditions. The steamer was coal fired. After the war, Green Island was returned to Casco Bay Lines where it continued to serve under its original name of Aucocisco until 1952.' The same source documents the system she worked: 'Access to naval support activities in Portland was all by watercraft with trips up to approximately three to six miles. Downtown Portland also served as a "liberty port" for sailors whose ships were moored or anchored in the bay.'

- Operating-environment documentation for the population this hull served: Casco Bay was selected as a destroyer base in summer 1941 for the Neutrality Patrol; U.S. Naval Shore Activities base established September 1941; Casco Bay designated fleet anchorage. Major functions: shakedown training for newly commissioned East Coast ships, refresher training after yard periods, specialized ASW training, destroyer-tender repair/upkeep, re-supply (Long Island Fuel Annex), convoy-escort and patrol staging, and local harbor defense. Moorings and anchorages at Long and Chebeague Islands. 'In 1944, there were more recorded ship visits (336) than in any other war year,' including battleships Arkansas (BB-33), Texas (BB-35), and Nevada (BB-36), 94 destroyers, and 178 destroyer escorts - 'virtually every DE that was assigned to the Atlantic Fleet during the war visited the bay.'

- Finding type

- Finding
- CORRECTION of a builder-attribution discrepancy: DANFS credits 'South Portland Shipbuilding Co.' while NavSource credits 'Portland Shipbuilding Co., South Portland, ME (also known as Nathan Dyer's Yard).' The South Portland Historical Society documents that the Ferry Village shipyard 'was originally established by the Dyer family and changed hands many times over its history, with many different names for the yard including Portland Shipbuilding Company.' The two citations therefore describe the same site - the 19th-century Dyer yard in Ferry Village - not two different yards, and NOT the WWII-era South Portland yard (New England Shipbuilding/Todd-Bath) that mass-produced Liberty ships 1940-45. Press Herald columns by the society's executive director corroborate the Dyer family operation at Pine and High streets, Ferry Village (paywalled; search-index excerpts only).

- The muster rolls of Naval Station Portland, ME - the activity this hull was allocated to (1st Naval District, Portland) - are digitized at NARA: 998 images covering 11 November 1942 through 30 July 1947, spanning her entire YFB-32 service (5 May 1942 - 18 December 1945). Yard-craft crews of this type were typically carried on the parent station's muster, so these rolls likely record the Navy enlisted complement of this ferry - an open lead for crew size and named personnel. COMDESLANT war diaries for the same window are likewise digitized in the catalog.

- asbestos_application
- Finding
- A coal-fired steam ferryboat built in 1897 and retained in steam through 1952 sits inside the era when asbestos and asbestos-compound lagging was the standard insulation of marine steam plant construction: boiler casing and drum lagging, steam-line and pipe insulation, flange and valve gaskets, and machinery packing aboard a vessel of this type and period were commonly asbestos-containing. Her 1942-45 naval service additionally falls inside the Navy's documented asbestos-insulation era (GAO: extensive shipboard use; substitution only beginning early 1970s). As a small wooden passenger ferry, her insulated footprint was confined to the boiler/engine space rather than distributed shipwide.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, conversion work package, or maintenance record located for YFB-32/Aucocisco. The 1897 build predates the documented WWII naval asbestos program, so inference rests on general steam-era practice plus her Navy-service window, not on a vessel record. No quantity, no manufacturer attribution, no present-day presence (hull scrapped 1954).
