Stena develops hybrid vessels, adapted for different fuels and prepared for electric operation. In 2025, the specially built RoRo vessels Stena Connecta and Stena Futura, equipped with rotor sails, were put into operation in the Irish Sea. These vessels are part of the NewMax concept – a concept adapted to maximise capacity within given port constraints, such as on the Belfast-Heysham route. C-Flexer is Stena RoRo’s next-generation future-proof RoRo vessel (cargo), while E-Flexer is a series of RoPax vessels (combined cargo and passenger). C-Flexer builds on experience from E-Flexer, but focuses on maximum freight efficiency, with preparation for alternative fuels and hybrid battery operation. All in all, the investments strengthen a flexible and future-proof fleet, ready for stricter climate requirements and changing market conditions.
