can accommodate 44-55 cars, depending on size. As there is 4.6m headroom below the car deck, sufficient height is available for trailer stowage. The lightweight consequences of the
extra deck structure and the hull sponsons are such that the maximum deadweight of the latest ships is 1150tonnes less than that of the preceding deliveries. Te increased internal volume has hoisted gross tonnage by nearly 8400gt to 33,960gt. Notwithstanding the design modifications
and the hydrodynamic consequences of fitting sponsons, the four-deck ships have a speed which is only marginally less than that

of the three-deck ro-ro’s. In common with the preceding ConRo220 vessels, Opaline is powered by a 10,800kW MaK medium- speed, 12VM43 main engine produced in Germany by Caterpillar Motoren. Te design service speed is 18knots, relative to the 18.5knots of the Mazarine quartet. The Flensburg yard can offer other
variants of the ConRo220 type, including a design with a more powerful engine of 12,000kW, for a 19knot service speed, and a Baltic trading version strengthened to 1A Swedish-Finnish ice class. Tis is closer to the specification adopted for two vessels under construction to the account of Finnish owner Bore. Te pair of newbuilds, dubbed the Bore RoFlex class, is destined for long-term charter to British operator Mann Lines. NA
