Masa-Yards and Silja Line have been actively developing the "Baltic Ferry Concept" since the late fifties and early sixties. The 665-1/2-foot Silja Serenade, although it incorpo- rates many of the design achieve- ments of the past, is unique because of the Silja Promenade. This "main street" is a huge atrium on her main deck, with a length of 470 feet, width of 27 feet and height of five decks. The promenade is accented by skylights atop and a glass wall at the aft end of the ship, thus provid- ing passengers with a view of both the sea and sky. Restaurants, shops, and other recreational and enter- tainment facilities are accessible from the promenade. In addition, two accommodation blocks are situated on each side of the promenade, with cabins facing either the sea or the main street. The Silja Serenade will have a gross tonnage of 58,376 tons, breadth of 103 feet, and design draft of about 22 feet. She has a passenger capacity of 2,500 in 952 cabins. Ad- ditionally, the Silja Serenade can also accommodate 450 cars or 60 trucks. Equipment List Equipment List Main engines .... GE Propellers Matsui/Nakashima Thruster Schottel Thriuster motor . .

With an overall length of 775 feet, beam of about 105 feet and draft of 39 feet, the 45,900-dwt Taihe oper- ates in the Pacific, calling at ports on the U.S. West Coast, Vancouver, Japan and Hong Kong. Her draft, beam and Stone Vickers bowthrus- ter enable her to operate and ma- neuver in constricted, congested ports and transit the Panama Ca- nal. Propulsion power for the Taihe is provided by a derated Clark-Kin- caid-MAN B&W 6L80MC engine, which develops 22,770 bhp at 88 rpm and a service power of 20,490 bhp at 85 rpm. The engine is capa- ble of operating on MDO or HFO to a viscosity of 420 cSt at 56 degrees C to achieve a service speed of 19 knots. She is fitted with a Stone Manganese propeller supplied by Weardale. The auxiliary power is produced by three Harland & Wolff 1,000-kw main alternators each driven by a MAN B&W Holeby 8L23/30 engine rated at 1,040 kw. Built with a longitudinally framed hull, the Taihe's container capacity is provided by six fully cel- lular holds, which can be arranged for both TEU and FEU stacks. Equipment List Main engine . .

The USNS Relentless is the last of a series of ocean surveillance ships built by Trinity Marine Group. The Baltic cruise ferry Silja Serenade, built by Finnish yard Masa, features a five-deck-high promenade. The Turku shipyard of Finnish builder Masa-Yards recently deliv- ered the cruise ferry Silja Serenade to Silja Line. When she goes into service between Helsinki and Stock- holm, the Silja Serenade will mark a new era in the ferry traffic in the Main engine Wartsila Vasa Auxiliary diesel Wartsil Reduction gear Renk-Tacke Clutch Renk-Tack CP Propeller KaMeWa Shaft & stern tube bearings & shaft seals Waukesha-Lips Electric motors & 40 Maritime Reporter/Engineering News
