"soft nose," vertical post, and a cruiser stern. The 

 entrance is sharp and sHs;htly hollow, the body is long 

 and begins well forward of midlength, and the run is 

 rather long and easy. 



There is a raised deck forward. Abaft this the sheer 

 is broken, with no bulwarks; amidships is an island 

 house, two decks high, on which is a 2-deck super- 

 structure containing the bridge structure. There are 

 three cargo hatches forward and two aft, foiu" pairs 

 of derrick posts forward and three aft. The ship has 

 a single stack. 



These ships measured 492 feet overall, 69 feet 6 

 inches beam, 42 feet 6 inches moulded depth, 28 feet 

 6 inches draft to load line, 17,615 tons displacement 

 loaded, 12,343 tons deadweight, 7949 gross tons reg- 

 ister, and had 8500 shaft horsepower geared turbines 

 which gave them a speed of 10)^ knots and a cruising 

 radius of 12,000 nautical miles. Scale of model is ?§ 

 inch to the foot.

STANDARD AMERICAN TANKER, TYPE 2-SE-Al 

 Rigged Model, usnm 313036 



This model represents a standard design turbine- 

 driven, single-screw tanker prepared by the U. S. 

 Maritime Commission before the last war. These 

 vessels were faster than most earlier American tankers 

 and were intended to serve the Navy in time of war. 



The model shows a tanker having moderate and 

 broken sheer, straight keel, straight raking stem with 

 a small "soft nose" and very angular forefoot, an 

 upright post, and cruiser stern. 



There is a short raised deck forward, with a break 

 in the sheer, a catwalk to the midship island, which 

 is two decks high and has upon it a superstructure two 

 decks high, containing the wheelhouse and bridge, 

 and a signal mast. A catwalk leads from the island 

 to the raised poop, one deck high, on which is a large 

 deckhouse, a smaller one, and a stack. Forward is 

 a derrick mast, and the ship also has a mast and two 

 pairs of derrick posts. 



This class of ships measured 523 feet 6 inches length 

 overall, 68 feet beam, 39 feet 3 inches moulded depth, 

 21,670 tons displacement loaded, 16,765 tons dead- 

 weight, 10,172 gross tons register, and had 6000 shaft 

 horsepower geared turbines which gave the vessel a 

 speed 14}^ knots and a cruising radius of 12,600 nau- 

 tical miles. Scale of model }i inch to the foot.

STANDARD AMERICAN CARGO STEAMER, 



LIBERTY SHIP, TYPE EC2-S-C1 

 Rigged Model, usnm 311022 



This model is of a standard design of wartime single- 

 screw vessel. Known as "Liberty ships," they were 

 built in American shipyards by mass production 

 methods. The design, a modification of a successful 

 British class of ships, was prepared under the direction 

 of the U. S. Maritime Commission to fit American 

 production requirements. The ships were commonly 

 of all-welded construction and had reciprocating steam 

 engines, as turbines were required for other vessels. 

 Liberty Ships served throughout the war as cargo 

 carriers and even as emergency transports; many were 

 lost through enemy action. 



The model represents a cargo steamer having mod- 

 erate and flush sheer, straight keel, straight raking 

 stem, upright post, cruiser stern, a long body and 

 deadflat, a short and full entrance, and a short but 

 easy run. Midsection formed with a slight rise in the 

 straight floor, a low and hard bilge on a short radius, 

 and an upright topside. 



There are three cargo hatches forward and two aft 

 to serve the five cargo holds; a single deckhouse stands 

 a little abaft midlength, and on it is a 2-deck super- 

 structure containing wheelhouse and bridge, a single 

 stack, and a signal pole to port of the foreside of the 

 stack. There are three derrick masts, and a small deck- 

 house lies right aft on the main deck. Some variation 

 existed in the deck arrangement of vessels of this 

 design. 



Liberty Ships measured 441 feet 6 inches length 

 overall, 56 feet 'lOY^ inches moulded beam, and 37 

 feet 4 inches moulded depth, drawing 27 feet 8% inches 

 when loaded. The ships were of 14,257 tons displace- 

 ment and 10,865 tons deadweight. The reciprocating 

 engines developed 2500 shaft horsepower, giving a 

 speed of 10}^ to 11 knots and a cruising radius of about 

 10,000 nautical miles. Scale of model is % inch to the 

 foot.

STANDARD AMERICAN CARGO STEAMER, 



VICTORY SHIP, TYPE VC2-S-AP 

 Rigged Model, usnm 313023 



This model is of a standard design of turbine-driven 

 single-screw merchant ship prepared by the U. S. 

 Maritime Commission early in the last war. This de- 

 sign was the result of experience with low-speed cargo 

 ships, which suffered heavy losses from enemy sub-
