BIG MAMA is a Riviera 78 (R78) motor yacht, the first R78 on the market. Synonymous with high performance and luxury on-water living — and coupled with the Luca Vallebone’s award-winning design sensibility — the R78 is an excellent opportunity to own a perfectly appointed Riviera without the wait.

Through electronic sliding glass doors is BIG MAMA’s galley and main salon. Well-appointed and with full-size fridges to both port and starboard, the open-plan space is designed for functional living and interactivity. Both spaces enjoy large windows — bigger than in older Riviera models — and allow unobstructed views. The main saloon is located forward; to starboard is a custom sofa with an ottoman and to port, a chaise longue. A large rug ties everything together. A 65” television is hidden in the ceiling and is also hooked up to the Raymarine navigation equipment — charts and cruising information can be shown to guests at the touch of a button. Completing the space is a fully equipped wet bar and remote-controlled electronic shades.

Stairs from the main deck lead to BIG MAMA’s luxury cabins, where she can accommodate up to seven guests across four suites. Her full-beam master suite features a king-sized bed, black-out blinds, wireless charging stations and a hidden refrigerated drawer bedside. Large hull windows to both port and starboard bring the outside in — as well as a good cross breeze when needed. A cedar-lined walk-in closet provides ample storage and an en-suite is complete with his-and-hers sinks and a rain shower. Each of her guest cabins also enjoys en-suites and cedar-lined storage, with a VIP forward featuring a double berth and a portside guest cabin with two side-by-side single berths. A fourth cabin to starboard has been converted to a private office, with a Pullman berth hidden in the aft bulkhead.

BIG MAMA’s exterior spaces offer plenty of opportunity for sunbathing and socializing. Her aft deck, accessible via steps to both port and starboard, has an alfresco dining area with a large table. It is enclosable via a weather canvas, allowing it to become an extension of the saloon. Above, her extended aft flybridge differs from other models in the series with a custom sunbathing deck boasting a large sunpad with a wetbar. The entire space is semi-shaded with a Bimini and hardtop, allowing for the ultimate views with cruising. Forward, the foredeck offers plenty of plush seating; while at anchor, a full sun awning can be raised. Her teak-laid swim platform aft provides easy access to the water and can carry easily her four-meter BRIG Eagle RIB with a Honda 60HP outboard engine.

For those seeking unparalleled luxury, customization and top-tier performance, BIG MAMA is the ultimate choice. With warranties, impeccable maintenance and unique features, she's a remarkable opportunity to own a yacht that stands out in style and sophistication.
