78 Motor Yacht Enclosed Bridge Deck

Following more than 40 years of evolution and with over 5,700 yachts in multiple styles built and now being enjoyed in all corners of the world, the 78 MY design represents a distinguished new era for Riviera.

The Riviera design group, in collaboration with award-winning superyacht designer Luca Vallebona, bring a combined passion for excellence to create a sophisticated yacht that delivers a perfect combination of family cruising, entertaining and blue-water passage-making capabilities.

The flexibility of the new 78 Motor Yacht design will allow owners to personalise their yacht to reflect their individual tastes and further enhance their lifestyle.

Saloon and bridge decks extend to the stern

The 78 Motor Yacht be available with an enclosed or open bridge deck and includes accommodation for up to 10 adults in four luxurious staterooms and crew quarters.

The saloon and bridge decks both extend through to the stern of the yacht, offering multiple dining, entertaining and relaxing spaces for parties, family gatherings or quieter moments.

Riviera Australia owner Rodney Longhurst describes the new yacht as “timeless and contemporary”. A range of premium fabrics and leathers are utilised extensively throughout the interior, combining with a painted finish to walls and headliners while superbly varnished, finely matched timber can be selected in high gloss or satin finishes.

Owners will be engaged with personalising their yacht from the very beginning of their build, deciding on furniture placement, colours and fabrics and how they wish to best utilise the many spaces on board.

One of the key interior design features is flush surfaces throughout – including the use of integrated refrigeration and icemakers.

The main saloon may include dining and lounge spaces or simply act as the grand lounge with dining focused on the aft deck which can be semi-enclosed, covered entirely by the bridge deck overhang and protected by optional clears. The large U-shape galley, with twin ovens, four-burner hob, comprehensive refrigeration and storage capabilities, has been positioned as a centrepiece of the entertaining spaces.

An internal timber staircase leads from the port side of the main saloon to the bridge deck which also offers lounge, entertaining and dining spaces. A bar is built into the aft deck and a day head is optional.

The highly versatile foredeck offers a number of entertaining layouts and a Euro sun awning with the option to carry a tender or jetski and davit.

An elegant curved timber staircase from the forward end of the main saloon leads to the accommodation deck with its four staterooms and three bathrooms. The full-beam Master suite amidships is bathed with natural light from extended hull windows. It provides an electrically adjustable king-size bed and extended his-and-hers en-suite bathroom. The VIP guest stateroom fitted with a queen double bed and also benefiting from hull windows is forward, with an en-suite bathroom. The port stateroom offers the option of a double bed or twin beds that can slide together. The starboard stateroom includes two single cross-over berths. A third bathroom is shared and can act as a day head.

Two doors are built into the exterior of the transom. A separate door on the starboard side provides access to the stand-up engine room and crew quarters. A larger door on the port side lifts to reveal a garage for water sports, diving and fishing equipment. A convenient shower is built into the underside of the door.

The unique teak-laid swim platform was developed in co-operation with Opacmare to provide a three-step design that can be lowered into the water to make access simple both for swimming and launching water sports equipment. A swim ladder is incorporated into the side of the platform.

With the design flexibilities for owners to reflect their individual lifestyle and personality in the Riviera 78 Motor Yacht, she will be admired in the bays, harbours, marinas and oceans of the world.
