24-Ft.-High Aluminum Superstructure Featured On MonArk Towboat MonArk Shipyard has announced the delivery of their hull No. 4 to Pitmarine Corporation of Pittsburgh, Pa. The vessel, named Betty Lou, is now in service in the Pittsburgh area on river construction and barge switching. Edward D. Fry, president of Mon- Ark Shipyard, said that the Betty Lou is one of the stock vessels that will be built by the Pine Bluff, Ark., facility, a newly formed subsidiary of MonArk Boat Company of Mon- ticello, Ark. In order to obtain the desired eye level without sacrificing stability, the superstructure from the main cabin top up was constructed of .125 alumi- num 5086 H-32 alloy. Although the operator has a 24-foot eye level, the weight above the main cabin top in- cluding double bunks, controls, in- struments and operator, is less than 3,000 pounds. Mr. Fry explained that this cabin may be purchased as a separate unit for installation on existing vessels. Although other types of boats have used aluminum cabins, principally high-speed offshore ves- sels, this is believed to be a first such skyscraper version used on an inland river towboat. "The additional cost IF WE GOT A CALLTODAYAT 3PM TO BUILD A MID-OCEAN TERMINAL, WE COULD GOTO W0RK0N IT AT $05. It's night. And an English container ship slips out of its berth for America. That same night an American container ship sails for England. But part of the English ship's cargo will never reach America. And part of the American ship's cargo will never reach England. Instead, both ships will dock in the mid-Atlantic. At a mid-ocean transfer terminal. Here's why. Both ships were loaded to capacity, but some of their cargo was bound for other destinations. So they off-load some containers and take on others. Then each ship continues on, completely filled with cargo for one specific destination. Think of it. Mid-ocean terminals for all the oceans on earth. And we could start to build them today Look at it this way We've been innovators in marine systems and shipbuilding for nearly a century. And today, we're the only shipyard that builds all three types of Naval nuclear ships. Submarines. Frigates. And carriers. And our interest and expertise in commercial markets continues to expand. Especially in the marine and energy industries. From super oil tankers and high-technology liquefied natural gas carriers to components and services for land-based nuclear power plants. So you see, we have the experience and confidence. Experience and confidence to go to work on tomorrow's marine systems. Right now. Today the world has plenty of seaports. And tomorrow there will be plenty of ports at sea. of the aluminum superstructure is offset quickly by the fact that the exterior was not painted and will never require paint," Mr. Fry said. Aluminum tower on the Betty Lou affords the operator a 24-foot-high eye level for safe navigation when pushing high barges. The Betty Lou is 41 feet long overall, by 15^ feet wide and 6 feet deep. She is powered by two Cum- mins NH-250 with 4.5:1 reduction gears turning an extra large blade cast steel 45-inch by 34-inch propel- lers. The propellers were custom built by Kahlenberg Brothers of Two Rivers, Wis., to MonArk Shipyard's specifications. The cold rolled shafts have stainless steel liners turning in BJ cutless rubber bearings. The en- gines are keel cooled with Fernstrum coolers and have dry exhaust using Maxim silencers. Special rock guards made of 4-inch O.D. x J^-inch wall pipe are provided under the vessel to protect the running gear and rud- ders when working around rock dikes and banks. The grounding gear is adequate to support the entire weight of the vessel and should it be neces- sary in a remote construction site, the owner would be able to simply drag the boat out of the water for any emergency repairs. Zach McClendon Jr., president of MonArk Boat Company, reported that due to its rapidly expanding sub- sidiaries, MonArk was seeking addi- tional new business and could offer quick delivery in either aluminum or steel boats.
