With a hydraulic lifter as standard, launching or retrieving a tender or watercraft is simple. Ideal for water sports or swimming when partly submerged.
The Riviera design team in collaboration with 4D designs have created this unique motor yacht. And everything about Riviera’s 645 SUV is impressive. The 645 has the largest water sports and fishing cockpit of all the models in our SUV Collection. When the alfresco deck opens up to our most spacious SUV saloon and galley, the single-level living plan is spectacular. And of course the 645 offers our largest SUV accommodation deck with a full-beam master stateroom. Choose three or four staterooms with three bathrooms plus an optional lower lounge and crew cabin, utility room or additional accommodation.
The three-seat helm station is expansive and the stand-up engine room is equally generous. And when it comes to performance, the twin shaft drive MAN turbo diesel engine options are the most powerful on offer in our SUV range.
You can personalise your 645 SUV with an array of interior packages and two design styles, the more traditional Classic Edition or avant-garde Newport Edition. Whichever you choose, from boarding platform to bow, you’ll relish the Riviera attention to detail, handcrafted luxury and exceptional operational technology.
Picture yourself on board your Riviera 645 SUV, exploring the great waterways of the world, diving in the Bahamas, or sport fishing on the Reef. Magic.
