Aqua City arrived in New York on her maiden voyage recently, ushering in what ACL calls "a new era in North Atlantic shipping." The 820-foot-long, 37,000-dwt Companion is the largest and most technologically advanced cargo ship ever built for the North Atlantic service, and like her sister ships to follow, was constructed to ACL de- sign specifications. Designated as "G3s" by the company, they are the first new vessels built for ACL in 14 years, and will replace the fleet of five Second Generation steam-tur- bine-powered ships now in opera- tion. Designed by TransConsultants AB of Gotaverken and built in the Malmo, Sweden, shipyard of Kock- ums, the Atlantic Companion has a capacity for 2,130 TEUs as well as space for 600 automobiles in the stern superstructure. Among the major features of the vessels are a large, multi-lane quarter stern ramp; permanent cell guides on the weather deck so that up to 1,410 TEU of containers can be stacked easily and safety, four per tier; and three decks for normal, heavy RO/ RO cargo or for the block stowage of containers. The cell guide structure, stern ramp, and other RO/RO equipment were supplied by Mac- Gregor-Navire. The consortium's vessels fly the British flag (Cunard), Swedish flag (Swedish American Line, Transat- (continued from page 17) Aqua City Maritime Inc. of Liberia, for charter to Showa Line Ltd. NKK has pioneered since 1978 in the design of sail-assisted ships in conjunction with the Japan Mari- time Machinery Development Asso- ciation. The shipyard built the first such vessel, Shin Aitoku Maru, in 1980; since that time, five smaller coastal and short-range vessels have been built and put into service in Japan. The first sail-assisted vessel to fly a non-Japanese flag, the Bahamian- registered Aqua City is now operat- ing in the Japan-Canada-U.S. West Coast trade. On her maiden voyage from Yokohama to Vancouver, B.C., she averaged 15.28 knots in sail- assisted operation and 14.86 knots using the engine alone at an output of 5,830 bhp. The vessel has an overall length of 590.2 feet, beam of 83.3 feet, depth of 47.6 feet, and draft of 34 feet. Her Sumitomo/Sulzer 6RTA58 main diesel engine has an output of 8,300 bhp at 99 rpm. Design service speed is 14 knots. Total area of the two sails mounted atop her forecastle is 352 square meters. The, two sets of parabolic-shaped, rectangular sails on steel frames are 16 meters high and 11 meters wide. Computer-controlled, they respond automatically to shifts in wind di- rection and speed, and are said to provide up to a 30-percent fuel sav- ing under the best wind conditions.
