Diesel River Towboat Bids For U. S. Engineers The United States Engineer office, Vicksburg, Miss., on May 29 opened bids for the construction and deliv- ery afloat at Vicksburg, Miss., of one steel hull, twin screw, diesel driven river towboat. These bids were in response to an advertisement issued April 24. The lowest bid received was in the amount of $314,750 and 180 days, from the Marietta Mfg. Co., Point Pleasant, W. Va., and it is under- stood that contract has been or will be awarded to this company. Other bids received were from the Midland Barge Co., Midland, Pa., $344,000 and 250 days; Chicago Bridge & Iron Co., Chicago, $339,800 and 300 days; Nashville Bridge Co., Nashville, Tenn., $364,850 and 360 days; and the Dravo Contracting Co., Pittsburgh, $343,630 and 250 days. Alternate bids were also made by Marietta Mfg. Co., Nashville Bridge Co., and the Dravo Contracting Co. This vessel is to be 176 feet in length molded, 38 feet in beam of hull molded and 8 feet, 6 inches depth molded. The two engines are to be of full diesel type, direct re- versible and are to develop 650 brake horsepower at 250 revolutions per minute. Besides the main propelling engine there are to be two 75-kilo- watt 125-volt direct current full die- sel driven generating sets. Naval Building Program The naval building program author- ized under the Vinson act is to be started promptly. The immediate pro- gram calls for an expenditure of $90,- 000,000, and will include one heavy cruiser, two 10,000-ton cruisers, 12 de- ‘stroyers, two destroyer leaders, and six submarines. This represents the start of the con- struction of 102 additional ships to bring the United States navy up to the London treaty limits. It is now expected that a request for bids will be submitted to shipyards within 50 days. At New York Fuel oil per ton per barrel Dis a 48.11.35 25.63 June 19, 1934.

This can now be done by the administration without further reference to congressional au- thority. Airplane Carrier Ranger The airplane carrier RANGER, built by the Newport News Shipbuilding & Dry Dock Co., was officially accepted by the navy department at Norfolk on June 4. She was placed in command of Capt. Arthur L. Bristol, by Rear Admiral Arthur St. Clair Smith, act- ing commandant of the Norfolk naval district. On her preliminary sea trials she is Said to have exceeded her designed speed of 2944 knots. Her general per- formance was also highly satisfactory. Tonnage of Normandie According to first estimates by the builder, the gross tonnage of the giant French linear NoRMANDIE£, now under construction, would be _ 68,000 tons. These estimates have now been revised on the basis of greater accuracy pos- sible as the vessel approaches nearer to completion, and it is believed that the gross registered tonnage will ac. tually be between 78,000 and 79,000 tons. British shipping men are speculat- ing on whether the tonnage of the new Cunarder will be altered in a similar manner from the original figures given of 73,000 tons. The gross registered tonnage is generally accepted as a measure of size. The question now is will the NorMANpre or the new Cunarder have the distinction of being the largest ship in the world. The McClintic Marshall Corp., Bethlehem, Pa., was the low bidder at.$85,140, for furnishing and deliv- ery afloat of 44 steel dredge pontoons to the United States engineer office, Vicksburg, Miss. Bids were opened on June 12. Bunker Prices At Philadelphia Coal Fuel oil per ton __ per barrel June 19, ae ‘ ‘ 1735 May 18.. Hees ee ai el kee pil eg peels: 5@4. .4.30@4. 60 ce 18 1933.

MARINE REVIEW—July, 1934 Model Experiments Used For New Cunarder Information has been received on several interesting features in con- nection with the construction of the Cunard superliner at John Brown & Sons, Clydebank. The vessel will have three funnels. The diameter of each funnel will be approximately 30 feet. The forward funnel will be more than 70 feet in height from the boat deck, with the two other fun- nels decreasing in height. F'rom the keel to the top of the forward funnel will be approximately 180 feet. Final design of the funnels was based on the results of numerous trials in a specially constructed wind tunnel. More than 30 models were tested. The rudder for the new liner weighs nearly 140 tons and is by far the largest ever made. It will be completely assembled and tests car- ried out to make certain that every detail is perfect. It will then be dis- mantled and transported in sections to the liner’s berth where it will be reassembled and fitted to the ship. To determine the design and form of the hull 16 models were used and over 4000 experiments were carried out in the model tank. In order to determine the proper position for the hawsepipes, a wooden replica of the bow of No. 534 was erected. A series of tests were made with models of the hawsepipes and of the anchors to establish perfec- tion in action. In a series of fullsized model cab- ins, constructed ashore, everything that goes into a typical stateroom in all three classes of accommodations will be given a critical practical trial. These rooms will be exactly like sim- ilar rooms which it is intended to build into the ship, and the model rooms will be fitted out to the last detail by experts in design and fur- nishings. In this way decorative and furnishing schemes to provide mavxi- mum comfort and restfulness will be established. Experiments will also be carried out in heating, lighting and ventilation of the rooms, Other Ports June 19, 1934 Boston, coal, per ton.$ 7.96 Boston, oil, Diese engine trimin bunk alongside oil alongside per gallon Hampton Roads, coal, per ton, f.o. i $5 Cardiff, coal, per ton..
