Stena E-Flexer Series Versatile ferries for the 21st century

Stena RoRo’s E-Flexer class of ro-pax ferries has rapidly become the benchmark for efficiency, capacity, and adaptability. The ‘E’ relates to efficiency and environmental performance, whilst ‘Flexer’ reflects the customisable potential of the concept. The flexible design is deployed across a range of markets, from freight- dominated routes, to passenger-focussed services, as well as a blend of the two.

Designed by Stena RoRo and Deltamarin and built in China by China Merchants Jinling Shipyard (Weihai) Company, E-Flexers represent a significant evolution in ro-pax shipbuilding, standardising the core hull and machinery design yet allowing bespoke adaptations tailored to the needs of customers. The design encompasses differing vessel lengths, power configurations - including LNG dual-fuel capability and hybrid battery systems- and customised bespoke interiors. There are now thirteen E-Flexers and a further two vessels in build, making the E-Flexer the most successful modern ro-pax platform.

This book reviews the evolution and implementation of the E-Flexer design with a detailed review of each vessel in service and those in build plus a look at related at a number of other Stena RoRo related designs including the NewMax and C-Flexer freight vessels.
