Shallow Draft Vessel Review —Jekyll Isle (continued from page 17) longitude readout. Radios are two Nautilus VHFs and one 1,000- watt SSB. For routing and oper- ational planning she carries a Furuno facsimile weatherfax sys- tem. The boat is designed for crew and passenger comfort as well as performance. For coastal day trips she can carry a master and up to 12 passengers. For offshore missions she has four berths lo- cated in the forecastle and two in the dinette area, providing ac- commodations for four crewmen and three to four guests. The ves- sel has central heating and air- conditioning throughout. TOWBOAT 'JOHN M. DONNELLY' In the shadow of the St. Louis Arch, Ingram Barge Company re- cently christened its new 9,000- bhp towboat, the John M. Don- nelly. Designed and built by St. Louis Ship, Division of Pott In- dustries, the vessel features the exclusive Hydrodyne hull, and is the third towboat in the Ingram fleet built by St. Louis Ship. The Donnelly's hull measures 200 feet by 50 feet by 11 feet 6 inches, with a normal operating draft of 8 feet 6 inches, and is designed to have an overall height of 38 feet 6 inches at design draft. The all-welded steel hull is heavily framed longitudinally and transversely, with the aft deck raised to provide additional strength to the stern. Propulsion power is furnished by three GM Electro-Motive Di- vision 16-645E7BA marine die- sels, each developing 3,000 bhp at 900 rpm, fitted with Falk 30MRV48 vertical offset, reverse/ reduction gears. The engines and gears are cooled with water cir- culated through a St. Louis Ship skin cooling system. The engines are started from the engine room only, and are controlled by WA- BCO pneumatic control equip- John M. Donnelly ment in the pilothouse and at each engine. Three five-bladed, stainless steel, 109-inch propel- lers turn in stainless steel lined Kort nozzles. In additional to the conventional engine room con- trols, the Donnelly is equipped with an Engine Monitor Inc. mon- itoring system featuring an alarm panel in the pilothouse and one in the engineer's control booth. Electric power is provided by two GM Detroit Diesel 150-kw diesel generator sets. A General Electric deadfront switchboard located in the soundproofed and air conditioned control booth is wired for parallel operation of the generators. Pollution-control equipment has been installed to bring the tow- boat into compliance with all ex- isting environmental protection requirements. All propulsion en- gine, reduction gear, and gener- ator diesel sumps, as well as the propulsion engine's lube oil filters and coolers, can be pumped by a Viking pump to the dirty oil hold- ing tank, or to a valved discharge connection on the main deck. Pro- vision is also made for pumping out the dirty oil holding tank to this deck connection. All bilge suctions are pumped via a Gorman-Rupp bilge pump to the oily water bilge collecting tank. A Hyde bilge pump draws from the oily water collecting tank and discharges to the Hyde separator, where separation and dispersal by gravity takes place. A St. Louis Ship FAST model 13-M sewage treatment plant treats the sewage from the toilet drains, and is valved to discharge the effluent overboard or to a flanged connection on the main deck.
