A one-of-a-kind opportunity to own one of Riviera’s most coveted, and no longer in production, models. WATERDOG is a stunning 5400 Sport Yacht Platinum Edition that has been exceptionally maintained since new by her original owner.

Inspired by the evolving lifestyles of modern yacht owners, the 5400 Sport Yacht redefines onboard living. Riviera’s vision was to create a yacht that seamlessly integrates elegant styling, cutting-edge technology, and effortless entertaining spaces. The result is a yacht that combines clean lines, rich interiors, and relaxed sophistication with spirited performance at sea.

Even before you step aboard, the yacht’s sleek profile, recessed hull windows, and sculpted lines make an immediate impression. Once inside, her spacious volume is immediately apparent, with an open layout that flows from the expansive cockpit through to the luxurious salon and below to the well-appointed accommodations.

Below deck, WATERDOG offers a three-stateroom, two-head layout, highlighted by a full-beam master suite with a private ensuite. Every detail reflects Riviera’s commitment to craftsmanship and comfort, from the high-gloss timber finishes to the thoughtful integration of light, texture, and space.

Recent services include bottom paint, Seakeeper maintenance, AC descaling, and generator service, ensuring WATERDOG is turnkey and ready for her next adventure. She is powered by twin Volvo IPS 950s, with only 355 hours.
