Panthalassa - which translates from the Greek as 'all the sea' - combines the space and comfort of a motor yacht with the pace and agility of a racing craft. With an innovative lightweight hull and mast and a maximum speed of 15 knots, the 56-metre ketch is designed to evoke the thrill of sailing and reinforce a connection with the water. The interior concept articulates the boat's structural form within the living spaces - the aluminium hull is expressed and complemented by a simple palette of natural materials, such as teak and saddle leather, to create a discreet sense of luxury.

The yacht has capacity for up to twelve guests and a crew of ten, and incorporates a range of spaces, from smaller, more private retreats to flexible, open living areas. The three levels - a fly deck, the saloon deck and the guest and crew quarters below, are connected by an oval stair, which is surrounded by a screen of light-reflecting rods to project daylight back into the living spaces. Skylights are also used to draw daylight down into the heart of the boat. In the main saloon, the lounge, bar, library and boardroom are opened up to create a generous central space. A glazed wall between the boardroom and the captain's deck maintains a sense of spatial continuity. The saloon deck features a variety of places to relax and an informal outdoor eating area, complemented by a more formal dining space inside. Along with storage for jet skis and two pascoe tenders, the yacht also features state-of-the art entertainment and communications equipment, discreetly integrated into the furniture and interior panels.

Rather than a single owner's suite with smaller guest quarters, Panthalassa's six individual cabins share similar proportions. Within these cabins the storage and service areas are located towards the centre of the boat to allow the curve of the hull to be exposed and the number of portholes to be increased to maximise daylight and views. An organic, curved chaise-longue lines the hull of each cabin to provide informal seating and a marble wall divides each room from its own private bathroom.
