The vehicles are housed over three decks. The European Causeway has a capacity of 1,771 lane metres, corresponding to 375 cars. Deck 3 is 791 lane metres and has a free height of 5.2m. Deck 2 is 833 lane metres and has a free height of 5.2m. Deck 1 has a length of 147m and a free height of 5m.

The European Causeway is powered by four Wärtsilä 12V38 engines, which each have an output of 7.92kW when driven at 600rpm. There are also two auxiliary engines. These are Daihatsu 6DK-28 units that have an output of 1,900kW each when at 750 rpm.
The engines are linked to two Kamewa propellers with a diametre of 4.25m, which rotate at 182 rpm. This gives the ferry a service speed of 22.7 knots, although it can attain a maximum speed of 24.95 knots.
For manoeuvring, the ferry employs two Kawasaki 1,260kW bowthrusters. To ensure a stable crossing, there is also a Litton stabilizer. The total consumption of the 380cSt quality fuel is approximately 123.9t/24hr.
The ferry’s tanks can store 1,032m³ of fuel oil and 124m³ of diesel, as well as 134m³ of lube oil. Other tankage also holds 260m³ of fresh water and 2,488m³ of ballast water. Fitted on the ferry are series 260 Tankstar-type approved sensors, digital display monitors and two indicator panels with analogue displays. The system provides digital indication within the ballast control room, with the panels mounted at the port and starboard fuel stations. The Series 600 Tankwatch self-powered gauges are also fitted as a secondary display, meeting regulations for passenger vessels and a lower-cost alternative to expensive sight glasses.
