fabric reinforced diaphragm history
The hull form of Effie M. Morrissey was modeled after the successful fishing schooner Fredonia of 1889, an improvement of the unstable Gloucester clippers of the 1850s-80s, with a sharp, clipper bow, elliptical transom, fine sharp lines, a lofty rig, and a deep draft that brought speed under sail and, as an "offshore" version of the Fredonia hull, served as a stable platform for offshore, deepwater voyages.[3] The schooner was and is built staunchly of white oak, treenail and iron-fastened with Swedish wrought iron, with later replacements in yellow pine and tropical hardwoods. The double-sawn oak frames, 7.5 by 6 inches molded and sided, are on 24-inch centers. The carvel-planked hull is 3-inch thick oak planks, treenailed with locust. The hull was sheathed with 2-inch thick greenheart after 1926 for Arctic voyages; this was removed in or around 1959 when the schooner served as a Cape Verde packet. In 1978, the hull was sheathed with fiberglass below the waterline, which the schooner retains. The ceiling planking, originally oak, has in time largely been replaced with yellow pine. Treenails have given way to spike fastenings. The hull is reinforced by a 4-inch thick bulge stringer. Hanging knees support each major deck beam, and the decks are strengthened by lodging knees throughout. The white pine deck, largely original, is formed of 3- by 5-inch planks, with a beaded undersurface, spike fastened to the deck beams. Replacement of deck planks has largely been confined to the foredeck area.

On deck, the schooner is fitted with its original steering gear and wheel, an 1891-cast "A.P. Stoddart, Gloucester" helm. The ironwork is all original, including the boom-bumper and horse, mastbands, and the two manual Edson diaphragm pumps. The windlass, a Gloucester-manufactured hand-cranked log windlass, is set forward. "Booby hatches" have been built and laid over the coamings of the fish hatches to provide all-weather pedestrian access below. Water barrels are lashed in place on deck, as are the ship's boats, along with two modern inflatable rafts. The radio antenna folds down and tucks alongside the aft-cabin deckhouse, minimizing the visual intrusion of the modern world. Firemains are below deck, but reach to the edge of the hatches, providing quick access to them in emergencies. Below deck, the schooner has a fully restored forecastle, with 12 varnished bunks, brass oil lamps, and the huge oak table. One feature of the forecastle is a steel truss rod, with turnbuckle, that was installed in the 1930s when the schooner began to loosen up with age.

The hold, subdivided into the midships berthing area and engineroom, accommodates 16 and two enclosed heads. Aft, and adjacent to the mainmast are four additional, enclosed berths. Between them and below, in the bilges are steel fresh water tanks and a waste holding tank. A watertight bulkhead with a water- tight door separates the accommodations from the engineroom. In addition to the engine and fuel tanks are two kilowatt generators, two flo-max, 3-inch pumps driven by 7.5-h.p. Baldor electric motors and the sewage discharge pump. The engineroom is completely modern, with aluminum diamond plates, fiberglass- wrapped exhausts, and welded steel pipe. The aft-cabin retains its original berths and varnished bird's eye maple and black walnut panelling, with a chronometer used aboard by Capt. Bob Bartlett during his Arctic voyages hanging on the forward bulkhead. The schooner is in excellent condition and retains outstanding integrity. The marks of a fire below decks in 1948, though painted over, are evident on some planks. Worn deck planks, and fittings evident in the earliest known photographs of the ship speak to the age of the vessel and retention of original fabric.
