Riviera has unveiled the new 645 SUV Series II, an updated version of its flagship SUV model that brings a redesigned interior, new technology and additional customization options to the 64-foot adventure yacht.
Building on the original 645 SUV introduced in 2021, the Series II retains the model’s combination of open-air entertaining spaces and offshore cruising capability while refining the onboard experience. The yacht blends the expansive cockpit and bluewater pedigree of Riviera’s Sports Motor Yacht line with the single-level salon and indoor-outdoor layout found on its Sport Yacht models.
The cockpit can be configured for watersports, entertaining or fishing, while an optional hydraulic swim platform expands usable space at anchor. The alfresco deck connects seamlessly to the salon and galley through sliding glass doors and a lift-up awning window, creating one continuous social area. Forward, the foredeck offers lounge seating and sun pads for relaxing underway or at anchor.
Belowdecks, owners can choose from three- or four-stateroom layouts with three heads. A full-beam master stateroom anchors the accommodations, while optional configurations include a lower lounge in place of the fourth stateroom, a dedicated utility room and laundry or additional crew quarters.
Power comes from a choice of twin MAN V-8 diesel engines rated at 1,300 hp each or twin MAN V-12 diesels producing 1,550 hp each. Available technology includes joystick maneuvering, remote vessel monitoring, Starlink connectivity, solar charging, and a choice of Humphree fin stabilizers or a Seakeeper gyrostabilization system.
The Riviera 645 SUV Series II is designed and built at the company’s Gold Coast, Australia, facility.
