Notes: The Skinner & Eddy Corporation established their original yard in 1916 to build 8800-ton Design 1013 "Robert Dollar" type ships for European interests. It was located in Seattle just to the east of the yard of the Seattle Construction and Dry Dock Co., the builder of the 7500-ton Design 1014 "Cascade" type ships, which was soon purchased by the Todd Dry Dock & Construction Co. Between 1916 and January 1918 Skinner & Eddy received orders for 35 Design 1013 ships (including 11 that were requisitioned and 20 for the EFC). On 27 May 1918 Skinner & Eddy, received Contract 309 for 15 more ships (EFC Hulls 1731-1745) which were built at Shipyard No. 1. In 1918 Todd sold the former Seattle Construction and Dry Dock yard to the Shipping Board who on 1 June 1918 handed it over to Skinner & Eddy for operation as their Shipyard No. 2., their original yard becoming Shipyard No. 1. On the same day the EFC awarded Skinner & Eddy, now with 10 building ways at its disposal (5 in each yard), its Contract 324 for 35 ships (EFC Hulls 1925-1959) of which 22 were built at Shipyard No. 2 and the others cancelled on 25 April 1919. On 18 July 1918 it followed this with Contract 447 for 12 "9600-ton" ships (EFC Hulls 2292-2303), all of which were also cancelled on 25 April 1919.

The ships in these three contracts (except Hulls 1925-1928 which were Design 1013) were built to two new designs (Designs 1079 and 1105), probably produced like the private one mentioned below by Skinner's design staff. Design 1079 was a shelter deck ship with three decks (shelter, upper, and second), two 'tween decks, and no hull islands (flush decked). If the shelter deck was fitted with "tonnage openings" that could not be closed, the upper 'tween deck became what regulations called a "sheltered space, not enclosed" and was excluded from the ship's registered tonnage and therefore from the canal tolls based on it. The deck below it lacked such openings and was the top of the enclosed and watertight portion of the hull. The plan view of EFC Design 1018 shows the tonnage opening at the after end of the shelter deck but the drawings of Design 1079 (above) do not show this feature, suggesting that it was a "closed" rather than "open" shelter deck design optimized for carrying heavy rather than bulky cargo. For an example with measurements of the difference between open and closed three-deck shelter deck ships see the page on EFC Design 1057-B. Design 1105 was a shelter deck ship with two decks (shelter and upper) and two hull islands like Moore's Design 1015. For more on shelter deck and full scantling ship types see also the page Contract Steel Ships by Category. Designs 1079 and 1105 were officially rated at 9600 and 9500 dwt respectively but were also reported as 10000 and 9600 dwt.

Following the April 1919 cancellations Skinner's design staff produced a larger and faster three-deck shelter deck design for four final hulls that the company built on its own account with "Robin" names in place of the cancelled EFC Hulls 1947-1950. After completing these the Skinner & Eddy yards ceased operations. Shipyard No. 2 reverted to the Shipping Board and became Seattle's principal ferry terminal, while the site of Shipyard No. 1 is occupied today by U.S. Coast Guard Base Seattle.
