Captain's Report

The Riviera 645 SUV measures 69’8” (21.23 m) with a beam of 19’1” (5.8 m). She’s powered by twin diesel inboards up to 3,100 hp total.

Report by Eric Colby

The Riviera 645 SUV places a premium on entertaining in the lower aft cockpit, alfresco deck, salon and bow.

Mission Statement

The Riviera 645 SUV came to life as a response to requests from the company’s dealers and customers for a larger motoryacht that places a premium on a single-level entertaining and living, according to Riviera owner Rodney Longhurst. Like the rest of the SUVs, the 645 can keep guests comfortable during an extended cruise and can entertain a crowd with equal aplomb. Riviera’s design team collaborated with 4D designs to offer three or four staterooms, three heads and a utility room with single crew quarters aft. She’s available in the Classic edition that has traditional teak and black caulking or the avant-garde Newport with hardtop wings and gray-caulked teak.

Riviera 645 SUV Major Features

  • Large cockpit
  • Hydraulic swim platform
  • Customizable bow area with spacious lounges
  • Tilt-out window between alfresco area and galley
  • Choice of accommodations deck plans
  • Full-beam master stateroom
  • Twin inboard engine options up to 3,100 hp combined

Like all Rivieras, the 645 SUV should be able to run in less-than-ideal conditions.

Riviera 645 SUV Features Inspection

The Stern. Immediately abaft the transom is a full-beam swim platform that has enough space for crew to pass between it and the hydraulic version that extends well aft and can accommodate a tender. There are two longer staple rails across the trailing edge with two smaller ones outboard. Riviera takes the extra step of putting middle rails in them to add safety. Passageways to starboard and port lead into the aft cockpit and close with two-piece gates. They have bottom sections that open aft and caps that lower over them.

While a hydraulic swim platform is an option on Riviera’s 64 Sports Motor Yacht, the one on the 645 SUV is standard.

The aft deck is left open with more than 90 sq. ft. (8.36 sq. m) of space and the depth is 30” (76.2 cm). In the transom, the 645 SUV comes standard with a centrally positioned lounge. An owner can opt for a centrally positioned aquarium-style livewell with lockers outboard on each side. In the deck, the aft outboard corners have rounded cutouts covered in stainless steel above vertically mounted 13” (33.02 cm) cleats to accommodate dock lines without threatening the finish. There’s more storage outboard in the gunwales. Forward to starboard there’s a bar with a grill and sink to starboard. To port is a top-loading freezer. Two steps on each side lead to the side decks.

Here the cockpit has the “Classic” treatment with teak decking and black caulk.

The Newport finish has subtler gray caulking for a more modern look.

The forward end of the cockpit has a grill and sink to starboard and a drop-in freezer to port.

The Bow. Before we head up under the protection of the hardtop, let’s check out the 645 SUV’s bow, which is accessible via a port-side entryway. An owner can choose between two layouts. One has a forward-facing bench behind a table with a triple-wide sunpad that has ratcheting headrests ahead. The other has an L-shaped lounge that extends across the front of the pilothouse and up the starboard wide with a shorter one to port plus a smaller fiberglass table. The ground tackle is in a raised section of the foredeck. The anchor passes through the stem and is retrieved by a windlass. Regardless of the layout, an optional shade is available to protect the bow from the sun.

Here we see one of two layout choices for the 645 SUV’s bow.

In this layout, there’s space for tender between the bow lounges.

The foredeck is raised slightly and notice the third cleat for securing a second anchor if necessary.

This plan shows the livewell in lieu of the transom lounge. It leaves the cockpit more open for fishing or other activities.

In this plan, we see the aft lounge and the larger bow table and sunlounge.

The Alfresco Deck. Heading back down the side decks to the aft cockpit, we make our way up centrally positioned steps to what Riviera calls the Alfresco Deck. Sometimes, the area is also called the mezzanine. To port is an inboard-facing lounge that converts into a day berth. Just ahead on the same side is a small bar that has an icemaker in the base. A TV folds down from a locker in the overhead. To starboard, an L-shaped sofa wraps around a teak table that’s hinged to make it easier to enter and exit the seating area. When the Newport package is chosen, there are acrylic side wings beneath the hardtop that provide further protection for the alfresco deck.

The alfresco area is protected by the hardtop that has a series of LED lights recessed into it.

The glossy wood table to starboard has a stainless-steel framework and is hinged to make it easier to enter the lounge.

The Galley and Salon. A sliding stainless-steel-framed door opens to provide entry to the galley and salon area. To create a feeling of oneness between the galley and alfresco area, a window to starboard opens out and aft, latching in place in the hardtop. The galley is to port and has premium stainless-steel appliances, solid-surface countertops and suitable storage. An island in the center is a natural serving area for the lounge that runs the length of the salon to starboard. A TV can be embedded in the island or forward in a cabinet that’s just abaft the helm area. A pantograph-style door to port just ahead of the galley opens to the side deck.

Here we see the galley to port and the table that slides out from the starboard lounge.

With the table out of the way, there’s an easier passage to the helm or the cabin stairs.

The Helm. On the 645 SUV, Riviera positions the helm to port with three high-backed leather captain’s chairs. There’s a walkway between the port-most seat and the center one and the digital shift and throttle controls are in a panel between the middle and starboard seats. The steering wheel is forward of the starboard seat. Three Raymarine multifunction displays are in a matte black dash panel that has air conditioning ducts in the base. The autopilot and other systems are in the flat on each side of the steering wheel. Opposite the helm, there’s a small bar area to starboard.

The captain and his/her two companions have good views out the windshield and the side windows open.

Riviera 645 SUV Accommodations Deck

In the four-cabin plan, the starboard quarters has single L-shaped bunks.

In the three-cabin plan, each stateroom has its own private head.

The Master Stateroom. Stairs adjacent to the helm lead below to the 645 SUV’s accommodations level. Aft, the master stateroom is full beam and has a sofa-style lounge to port beneath the massive hullside window. There’s an equally large window to starboard where there is an assortment of lockers and drawers.

The head is to starboard and has a separate shower and an overall spacious feel.

The master stateroom has an expansive feel thanks to headroom approaching 7’ and large hullside windows.

The master en suite has a separate shower that’s bigger than the whole cabin on some boats.

The VIP. Forward, the 645 SUV’s VIP stateroom is in the bow. It has an island berth and looks to have at least 6' (1.83 m) of headroom. A flatscreen TV is on the aft bulkhead. Storage is provided in four drawers in the berth base and in a large hanging locker. The en suite head has a separate shower stall, a vessel sink and top-shelf-quality fixtures.

Even in the VIP in the bow, there’s a feeling of openness with the hullside windows and two overhead deck hatches.

Guest Cabins. Moving aft, the port guest cabin has two single berths that can be slid together to form a larger one. It has private access to the day head. If an owner opts for the fourth cabin, it’s to starboard and has bunk-style over under berths. Guests in this cabin must enter the day head from the companionway.

Laundry-Engine Area. Just off the master is the laundry/utility room that has a separate washer and dryer. A watertight door opens the engine room that can also be accessed from a hatch in the mezzanine. Available engines include the standard twin 1,300-hp MAN V8 diesel inboards and the upgrade to 1,550-hp MAN V12s, both with V-drives. Above each engine are the MAN control boxes and MasterVolt battery chargers. A Seakeeper is an available option.

The space between the master and the engine room can be set up to an owner’s preference and the laundry is a popular choice.

Observations

The Riviera 645 SUV will make her official debut in April and looks to be a worthy flagship for the series. A company that listens to its customers, Riviera decided to come out with the model when the owner of a 575 SUV told the company, “I’m really happy with my 575 but give me a call if you ever do an SUV version of the 64 SMY.” 

After returning from a Riviera owners event, the customer got a call that the manufacturer was moving forward with the 645 SUV and he ordered one without seeing so much as a drawing.

The 645 SUV combines the ability to cruise offshore for which Riviera yachts are known with outdoor and indoor gathering areas that have the luxury that enthusiasts expect from the Australian manufacturer. Keep an eye out for a full test of the yacht.
