On Sunday 16th May 2010, the first of two new Superferries made its maiden voyage from Hook of Holland to Harwich.  The largest ferries of their type in the world, each will be capable of transporting 230 cars, 300 freight vehicles and have 1,376 beds and 12 kennels on board. At 240 metres in length, each Superferry would be 2.4 times as tall as Big Ben (98 metres) if stood on their end. Designed to have a low environmental impact, the Superferries are also the greenest in the world. Eco-friendly features on the new Superferries include catalytic converters, an improved hull design, highly efficient engines and better combustion rates, all helping to reduce environmental impact. The ferries have facilities to recycle glass, cardboard and food waste onboard, while solar film on all windows will exclude up to 82% of the sun’s radiant heat, reducing the energy used by the onboard cooling system.
