Princess S78

Distinctively cool whilst propelling you to an exhilarating 39 knots, the all-new S78 is the flagship of the Princess S Class. Her sportbridge inspires relaxation with a range of exclusive furnishings to choose from and seating areas that convert into sun loungers. Unique central access from her hydraulic bathing platform to the cockpit passes between twin sunpads whilst her foredeck features innovative seating with sunpads which can be converted to create additional aft facing seats. The perfect ambience is ensured across her sportbridge, saloon, cockpit and master cabin, where the world class NAIM Audio sound system comes installed as standard. Refined and captivating, she’s more than everything you would expect from the largest Princess S Class.

Experience traditional craftsmanship reinvented throughout her integrated interior. Ambient lighting plays a supporting role behind furniture, feature panels and through flooring. A cavernous main deck saloon seamlessly connects you to the world outside through full length side windows. Her well-equipped galley surpasses the highest of expectations whilst her dining area delivers a sense of versatile space with an ingenious sliding glass table. Below deck eight guests enjoy four beautifully appointed en suite cabins all bathed in natural light from the S78’s elegant and expansive glazing, with a further aft cabin for occasional guests or 2-3 crew.
