Some Incat 96 and 98 metre vessels are fitted with hoistable mezzanine decks enabling the stowage of cars on two levels. Deployed with a minimum of fuss, as and when required, the decks provide the operator with the flexibility to adjust load plans of a highway mix of traffic to suit sailing fluctuations.
To take advantage of shoulder seasons or night freight runs, the mezzanine decks may be raised to deck head level to allow a concentration of freight vehicles. Alternatively the decks may be split to accommodate a mix of cars and freight, suiting the operator's needs on any given sailing.
On the 112 metre vessels a full length upper car deck features above the main vehicle deck thereby leaving the latter free for shipment of a full load of freight vehicles and buses. The lower deck can be built to allow semi-trailers to turn on board.
