The new Y78 features the very latest in Princess exterior design and interior materials and finishes. Her flexible deck layout features a walkthrough foredeck with U-shaped seating and sunbathing area, whilst her flybridge aft has space for free standing furniture or can accommodate a crane and a tender. Natural light flows in to her main deck through extended window lines and a unique full-height window on the port side to make the free standing dining area a spectacular place to entertain. Forward on the lower deck, all three guest cabins are en suite whilst a dedicated staircase leads to the owner’s stateroom amidships via a private lobby area.
