It's 7:30 on a Saturday morning in Boca Raton. You're on the flybridge with coffee in hand, watching the sun climb over the Atlantic. Your wife is still asleep in the full-beam master. The kids are in the VIP, probably scrolling their phones. You've got 1,004 gallons of fuel, twin MAN V12s idling below, and a sapphire-blue hull that looks like it was dipped in the deep ocean itself.
You're not thinking about the office. You're thinking about the 30-mile run to Delray, lunch on the hook, and whether you'll push the throttles to 37 knots on the way back just because you can.
This is what the Riva 66' Ribelle was built for.
Who This Boat Is For
The 66' Ribelle is for the owner who wants a sport cruiser that doesn't apologize for being fast. You've probably owned a center console, maybe a 50-footer that you ran hard on weekends. You know what 30 knots feels like, and you're not interested in giving that up just because you want three staterooms and a flybridge.
You're also someone who values design. Riva doesn't build boats for people who think "Italian styling" means chrome and marble. The Ribelle's lines are aggressive without being cartoonish. The sapphire-blue hull is a signature move, and the nearly full-length hullside glass gives the salon an inside-outside feel that most 66-footers can't match.
This is not a boat for the owner who wants to cross oceans or live aboard for months. The 710-litre fresh-water capacity and Riva's published 250-nautical-mile range at a 33-knot cruise tell you everything you need to know. This is a weekend warrior with a pedigree, built for the Bahamas run, the Keys, or coastal Florida cruising where you're never more than a few hours from the next marina.
Design and Layout: Form Meets Function
Riva's design team created a yacht that looks like it's moving while tied to the dock. The bow is sharp, almost knife-like, and the sheer line runs straight from stem to stern without the bulbous flybridge overhang you see on most sportfly yachts. The result is a profile that reads more like an express cruiser than a three-cabin family boat.
The salon is where the layout starts to make sense. Low-back L-shaped seating to starboard keeps guests within earshot of the lower helm while maintaining clean sightlines to the water. The electric high-low table adjusts for breakfast, lunch, or cocktails, and the cockpit door disappears belowdecks to create a 40-foot-long entertainment zone from the transom sun pad to the helm.
The master is full-beam amidships with a centreline berth and en suite head. The VIP is forward, and the third guest cabin is to port. Riva lists three cabins and three bathrooms plus a crew cabin with its own bathroom aft, and most owner-operators will use the crew cabin for storage or gear.
The flybridge is where you'll spend most of your time underway. The helm has clean sightlines in all directions, and there's enough seating for six guests. The hardtop is raked, which adds to the yacht's aggressive profile but does create some visibility restrictions at the lower helm during hard-over turns. It's a trade-off, and one that most owners will accept given how good the boat looks from the dock.
Performance: Speed as Freedom
Twin MAN V12 diesels rated at 1,550 horsepower each push the 66' Ribelle to a top speed of 37 knots. Cruise is 33 knots, and Riva puts the range at that cruise at 250 nautical miles on 1,004 gallons of fuel. There is one engine option and Riva publishes one set of figures, which makes this a simpler boat to shop than most of the range.
These numbers matter because they define how you'll use the boat. At cruise, you can run from Fort Lauderdale to Bimini in under two hours. You can make the Palm Beach-to-Miami run in 90 minutes. You can leave the dock at 8 a.m., spend six hours on the hook in the Bahamas, and be back at the dock by sunset with fuel to spare.
The Ribelle planes easily and tracks true. Steering is real-time responsive, and the yacht heels moderately inboard on hard-over turns. It's not a center console, but it's closer to that driving experience than most 66-foot yachts. The V-drive setup keeps the engines low and centred, which helps with weight distribution and handling. Ask about the current stabiliser options — on a boat this size it is the choice that most changes how the evenings at anchor feel.
The lower helm is forward of the salon. Most owners will drive standing up, especially in tight quarters or when docking, and the controls fall naturally to hand.
Ownership: What It Costs to Run This Boat
Let's talk about the reality of owning a 66-foot Riva with twin 1,550-horsepower diesels. This is not an inexpensive boat to operate, and anyone who tells you otherwise is selling something.
Riva publishes range but not fuel burn, so get observed gallons-per-hour at cruise from the dealer in writing rather than working backwards from a number someone guessed. Whatever it comes back as, add dockage, insurance, maintenance and crew if you hire help, and you're looking at six-figure annual operating costs.
But here's the other side of that equation: this boat gives you the freedom to go where you want, when you want, at speeds that most yachts in this size class can't match. You're not waiting for weather windows or planning multi-day passages. You're running hard, getting there fast, and spending your time on the water instead of in transit.
Most owners will run this boat themselves, possibly with a part-time captain for longer trips or when entertaining clients. The systems are straightforward, the handling is intuitive, and the boat is small enough to dock without a full-time crew. If you're coming from a 50-foot center console or express cruiser, the learning curve is minimal.
Maintenance on the MAN V12s is predictable but not cheap. Budget for annual service, oil changes every 200 hours, and major service intervals at 1,000 hours. The good news is that MAN has a strong dealer network in South Florida, and parts availability is solid. Resale on Riva yachts holds reasonably well, especially if you keep the boat clean, maintain service records, and don't over-customize.
Where to Start
The Riva 66' Ribelle is a sport cruiser for the owner who refuses to choose between speed and comfort. It's a boat that runs like it's being chased, looks like a piece of Italian sculpture, and delivers a driving experience that most 66-footers can't touch.
If you're serious about this boat, start by getting on one. The photos don't do justice to the sapphire-blue hull or the way the salon opens to the cockpit. Sit at the lower helm, stand on the flybridge, and walk through the master stateroom. Then take it out and push the throttles forward. You'll know within the first five minutes if this is your boat.
