2026 Riviera 645 SUV

The Riviera 645 SUV is a 64-foot fiberglass sportfish yacht built with a single-level open layout that connects the expansive saloon and galley to a large water sports and fishing cockpit. Twin MAN diesel engines producing 3,100 horsepower deliver a cruising speed of 30.5 knots and a maximum speed of 34.7 knots, paired with joystick control and trim tabs for easy handling.

The yacht sleeps up to four cabins with four heads. The layout features a full-beam master stateroom on the accommodation deck, with flexible configurations that can include three or four staterooms and an optional lower lounge, crew cabin, or utility room. The three-seat helm station sits above a spacious stand-up engine room.

The 645 SUV is available in two design styles: a Classic Edition or Newport Edition. Both offer a range of interior packages and showcase Riviera's finish quality and integrated automation throughout.
