PT Cahaya Samudra Shipyard in Batam, Indonesia, has delivered the first of two new next-generation 33 meter Incat Crowther designed ferries to Dumai Express Group. Named Ruby of Dumai<\/em>, it has completed sea trials and will soon commence operations in Indonesia<\/p>\n The new 33-meter ferries build on the success of a fleet of first-generation 30-meter catamarans designed for Dumai Express by Incat Crowther. They will deliver improved operational efficiency thanks to an extended stern, customized hull form an propeller tunnel.<\/p>\n The design enhancements mean Ruby of Dumai<\/em> provides a full-load draft of just 1.5 meters, allowing better access to more local ports and infrastructure, while offering significant fuel savings, reduced carbon emissions and faster trip times.<\/p>\n The vessels have also been future proofed allowing the operator to choose between different twin MAN D2862 engine set ups \u2013 a high speed 1,324 kW option, or a standard 1,066 kW option.,<\/p>\n Ruby of Dumai <\/em>provides a capacity of 271 passengers across a functional two-deck layout that offers spacious passenger cabins, expansive views and a comfortable travel experience. The vessels\u2019 main deck, capable of seating 213 passengers, features midship entry doors for central boarding near the stairs to the upper deck, with luggage racks positioned both centrally and at the forward end of the cabin.
