Stewart & Stevenson Deliver Three Crewboats To Italy Stewart & Stevenson Services, Inc., Hous- ton, Texas, has provided three unique crew- boats for Impreso U Girola Estero, a joint venture of Italian firms. The Stewart & Stevenson vessels, built at Houston's Glen- dale Boat Works, have passenger capacity of 28 persons or a 4,200-pound payload. Speed of the crewboats, powered by two 300-horse- power Stewart & Stevenson DIESELJET engines, exceeds 30 mph. The Stewart & Stevenson powerplants are turbocharged and inter-cooled. Shown above is Stewart & Stevenson's 6V53TI-DJ crewboat, recently built at Glendale Boat Works for a joint venture of Italian firms, Impreso U Girola Estero. Stewart & Stevenson was brought into the project by the Italian firms to solve an un- usual problem in construction of an inter- connecting freeway around the Port of Lagos. The freeway includes several bridges being built from island to island across sev- eral rivers. A major difficulty involved trans- portation for job foremen, roof men, and suppliers. Using traditional land transporta- tion vehicles, it took as much as two hours for crews and suppliers to reach some of the job sites. With Stewart & Stevenson's crew- boat, that time has been reduced to under 30 minutes. In all, three of the Stewart & Stevenson crewboats have been delivered to Impreso U Girola Estero at a total cost of $225,000. The crewboats have an overall length of 31 feet 6 inches and a beam of 11 feet 6 inches. They feature an extremely stable design that provides high maneuverability even in shallow depths, operating efficiently in only two feet of water. The boats include com- plete acoustic insulation for both the engine room and the passenger compartment, sky- lights for the passenger compartment, and removable seats to provide a quick change from crew to cargo-carrying uses.
