Thinking about upgrading to a more stylish boat this year? Is the late spring weather this year is getting you down and you can’t take it any more? We may have a solution… Stop what you are doing, call up your friendly travel agent and book a flight for you and your family to travel across the pond to beautiful Italy in late May…

And make sure you tell your travel agent that you want to stay in the area of the Villa d’Este on Lake Como, Italy on the weekend of May 24 – 26th. Then give the nice folks at RM Auctions a call and pre-register as a bidder for the RM Auctions’s upcoming sale during the Concorso d’Eleganza Villa d’Este weekend.

This could be your chance to purchase a rare Cadillac powered Riva speedboat and get it back to America just in time to make the prime classic boating season. It could be a story for the ages, one that you could share with your neighbors at the cottage for years… as you cruise across the lake in your elegant, timeless Riva. (Or you could simply register with RM Auctions as an on line bidder and buy it from home, but that wouldn’t be much of a story for the guys at the lake…)

Here’s the official Press Release from our friends at RM Auctions.

RM AUCTIONS OFFERS UNIQUE RIVA TRITONE ‘SPECIALE’ AT ITS CONCORSO D’ELEGANZA VILLA D’ESTE WEEKEND SALE

Villa Erba

• RM Auctions secures fabulous 1960 Riva Tritone ‘Speciale’ Cadillac for its highly anticipated sale in Cernobbio on Lake Como, Italy, on the 25th of May
• Custom-built powerboat represents the biggest, best, and most powerful Riva of the Golden Era
• Auction to also lift the hammer on the only surviving 1956 Riva Ariston Cadillac
• Exclusive evening sale held in conjunction with the celebrated Concorso d’Eleganza Villa d’Este

LONDON (5 March, 2013) – Collectors and connoisseurs are eagerly looking ahead to the opportunity to acquire some of the world’s most exotic and exclusive vehicles when RM Auctions hosts its forthcoming biennial sale during the Concorso d’Eleganza Villa d’Este on Lake Como, Italy, on the 25th of May. Alongside examples of historic cars from such celebrated marques as Ferrari, Bugatti, and Rolls-Royce, the exclusive evening sale will also proudly present a remarkable and historically significant 1960 Riva Tritone ‘Speciale’ Cadillac Powerboat.

If ever a vehicle embodied the spirit of la dolce vita in the 1950s and 1960s, it is the series of glorious wooden powerboats built by Carlo Riva from his bespoke yard on Lake Iseo. Riva’s sumptuous, hand-crafted wooden sports machines very quickly established themselves among the world’s elite, from royalty to movie stars, including the likes of Brigitte Bardot, Peter Sellers and Sofia Loren. Yet despite the wealth and status of his clientele, Riva made a point of refusing to build custom boats or indulge bespoke requests—all except one, that is.

Achille Roncoroni was an industrialist from Como and an accomplished mariner, and he even represented Italy in sailing at the 1948 Olympic Games. He was also a regular customer for Riva and requested that the distinguished boat manufacturer build him a unique example of its range-topping Tritone model to be the largest and fastest Riva ever seen—and that he should never build another custom boat thereafter. Riva acquiesced, and in 1960, this genuine, one-of-a-kind boat duly appeared.

The Tritone ‘Speciale’ Cadillac, named Ribot III by its owner, lived up to Roncoroni’s expectations in every way. Her 8.3 metre hull remained the biggest for many years, and the 325 horsepower Cadillac Crusader Marine V-8 was the most powerful engine available at the time. New lettering was forged for the hull and dashboard, while the bespoke interior of blue, red, and white was specially crafted. The engines were finished in red rather than blue, and the inside of the hull was painted white, as opposed to the usual grey.

The performance demanded by its Olympian owner was amply demonstrated by the 650 horsepower Ribot III on its pre-delivery test runs. In the hands of the youngest and bravest of test drivers, the boat presented here reached a remarkable top speed of 96 km/h (60 MPH), establishing a new record for a Riva runabout powered by stock engines and propellers. Thereafter, Roncoroni made great use of his prized Ribot III on Lake Como and at his holiday home in Sardinia before it passed onto its current owner in the early-1970s.

Peter Wallman, Car Specialist at RM Auctions, says, “RM is delighted to have been entrusted with finding a new home for the recently-restored Ribot III. Riva was one of the greatest status symbols found throughout the Mediterranean in the Golden Era. We are thrilled to have had a Riva consigned to this sale on Lake Como, but to have Ribot III is truly fabulous. This example has performance and specification that no other boat manufacturer can match, and such exclusivity that even the King of Jordan could not convince Riva to build another to this specification. It also has authenticity in the original fittings and sympathetic restoration by Giacomo Lazzari to amazing condition”.

Two owners from new and offered for the first time in more than 40 years, this wonderful powerboat represents a unique opportunity for enthusiasts, investors, and Riva aficionados to acquire a truly unique piece of boating history. It is expected to fetch between €550,000 and €750,000 when it goes under the hammer at the May auction.

In addition to Ribot III, RM’s upcoming sale during the Concorso d’Eleganza Villa d’Este weekend will also feature a powerful 1956 Riva Ariston Cadillac. Named ‘Slughi’, it is one of just six Aristons fitted with the powerful 250hp Cadillac engine in 1956. Additionally, it was the second of just 19 boats built, of which it is today the only surviving example from that year. Having spent its entire life in Italy, it is freshly restored and estimated between €180,000 – €220,000.

Lot 138
1956 Riva Ariston Cadillac “Slughi”
€180.000 – €220.000

• Hull no. 101 250 bhp, 365 cu. in. Cadillac V-8 engine. Length: 6.45 m (21 ft. 2 in.)
• One of 19 Cadillac-powered Riva Aristons
• The only example from 1956 known to survive
• Sold new in Italy and has been a resident here ever since
• Beautifully and authentically restored

One of the most successful of all Riva wooden runabouts was the Ariston, named for the celebrated Milan movie palace and translating from Greek to “the best”; not humble, perhaps, but in the end, an apt choice. The Ariston combined Riva’s original runabout design with inspiration from Chris-Craft’s delicately rounded “barrelback” stern, giving it lightness and elegance.

Only 19 examples of the Ariston were outfitted with powerful Cadillac engines: six in 1956, eight in 1957, and five in 1958. This is the second example ever built, and it is most likely the oldest to known to survive. Hull number 101, known as Slughi, was outfitted with a 250-horsepower V-8 engine. As a comparison, Chris-Crafts at the time were available with a 158-horsepower inline six-cylinder engine.

Delivered new to Sig. Dolci, an industrialist from Milan, Slughi is believed to be unique among the 19 hulls, as it was built during the change from Riva’s traditional two-piece windscreen to the new, and soon to be iconic, panoramic design. The hull was fitted with the two-piece unit, but it was drilled to accommodate the latter, should the client elect to make the change to the modern design.

Fated to never leave its home country, Slughi was retired from service in the mid-1960s and stored in a hangar on the Italian Riviera for decades. It was discovered in 2004 by a master marine carpenter and expert yacht restorer, M. Guastini, who embarked upon a complete restoration, which included installing new planking on the deck.

The next two owners continued the restoration, locating many missing, rare original parts, with the present caretaker completing the work at the Albertoli yard on Lake Maggiore. The original planking on the sides of the hull was saved and retained, whilst the bottom was replaced and reinforced, as on many old Rivas, for safety purposes. The original Cadillac V-8 was restored with much care, and the upholstery was restored to its original pattern.

The result is a spectacular boat of class, elegance, and refined Cadillac power. Slughi is ready to be enjoyed this summer season and will be delivered with its Cantiere Riva blue cover and its wooden berth.

In addition to Ribot III, RM’s upcoming sale during the Concorso d’Eleganza Villa d’Este weekend will also feature a powerful 1956 Riva Ariston Cadillac. Named ‘Slughi’, it is one of just six Aristons fitted with the powerful 250hp Cadillac engine in 1956. Additionally, it was the second of just 19 boats built, of which it is today the only surviving example from that year. Having spent its entire life in Italy, it is freshly restored and estimated between €180,000 – €220,000.

    Go for it Matt. Put some white fins on it and it will look almost like that 21ft. Continental, only faster!

  2. Jim Staib

    Chad,
    If you go remember to leave your monkey at home. Remember what happened to the Bebe’s monkey when he brought it to Europe!

  3. Paul H.

    Love the Tritone’s, but I don’t know – maybe Jimmuh’s is a bit more special, because it begat almost all of them.

    • Jimmuh

      A great 2nd choice though…..and a worthy successor to PERLITA…

      And Lago di Como definitely surpasses Lake Washington….

      (still too early for the Riva gentle-folk I guess…)

  4. Gary

    Obviously there is a bunch of Italian engineering going on on that Cadillac engine in the Riva Ariston. The photo shows the top of the transmission and the engine placard but blowing it up distorts it too much to read the model number.
    Any chance of RM getting that information?
    Chrome plating the exhaust manifolds is a sweet idea on the part of the Italians!

    • Texx

      Gary – Here is an excerpt from the RM Catalog description, you can see the entire description by clicking on the link to the catalog above.

      Outstanding features include a length of 8.30 metres, more than any other Riva of its era, and two Cadillac-Crusader Marine V-8s produce 325 brake horsepower each, some 100 brake horsepower more than the most powerful stock Riva Super Tritone.

      A marine conversion of the same engine that powered the Cadillac Eldorado, the Crusader was built by Calvin “Cal” Connell, of Cadillac-Crusader Marine in Warren, Michigan, who described it as “manufactured with the skill and precision to be expected of a product bearing the name Cadillac…

      The engines have been completely engineered for marine use and contain many features new to the marine industry. It is the lightest and most powerful standard production V-8 marine in the world. Between 1955 and 1960, it broke four international speed and endurance records”.

      In August 1961, the harshest offshore competition on the European side of the Atlantic, the Cowes Torquay race, was won by Thunderbolt, a small cabin cruiser driven by champion Tommy Sopwith, heir of the famous Sopwith aeronautical firm. Thunderbolt was powered by two “stock” Cadillac Crusader 325-brake horsepower, 390-cubic inch V-8s, exactly the same as the engines selected one year earlier by Carlo Riva and Achille Roncoroni for Ribot III. It was decided that in order to highlight the functional beauty of the red-painted Cadillac power units, the interior of the hull was finished in white rather than the usual grey, at Roncoroni’s order, so as to make the inner engine bay sparkle.

    • Jim Staib

      Gary,
      Here is a shot from the Cal-Connell catalog. The way I read it a single 4bbl was 250hp. The low profile model was 265hp. And Dual quads were 285hp.

  5. 72hornet

    Wow, wow and more wow. Love the lines on the Rivas and of course the detail on the Cal Connell Cadillacs. Stunning to say the least…..

  6. Cobourg-Kid

    It’s incredibly odd that out of 19 Riva Ariston’s crafted by Riva in 1956 only Slughi survived.

    What the heck? That’s less than a 5% survival rate for a boat built in the 50s, .There are hundreds of Century Coronado’s still out there from that era and they were not built to last!

    Even when I was a kid Rivas , even in atrocious condition, were worth a pile-O-money. So logically one would think that most of those 19 boats would still exist, after all you don’t consign valuable art to the burn pile and, like it or not, a Riva is mobile art .

    Hey viewers, any theory’s why so many up and vanished (that don’t involve a monkey) Perhaps they are just lost in a forgotten section of Carlos Riva’s cave?

    • Jimmuh

      C-K ,
      A couple of things:
      -there were not only 15 Aristons in 1956, there were 34 AR, including 6 AR Cadillacs, with 13 more AR Cadillacs in 57 & 58,
      -the 331 Cad was somewhat notorious for oil pump failures; perhaps a real service problem in Europe at the time,
      -Rivas were the province of the ‘rich & famous’; when the next big thing came along, the old Riva was gone,
      -they were ‘run hard & put away wet’, often in the ocean,
      -just like 21′ Capris, E-types, and any number of more exotic cars; by the time they got to their 5th owner, maybe the cost of maintenance was too much to deal with….
      -only very recently has the wooden boat hobby in Europe brought out many ‘barn finds’; there may be another AR Cad waiting patiently in a shed near Lake Geneva, CCC long gone, maybe a CC V8 in place, corroding fasteners pushing their way to the surface, ahhhg! can’t face it again……..

  7. Jim Staib

    Anyone else find it fishy this post appears the next day after the DONATE button story. Looks like a Riva in the Crystal boat house!

  8. mike k

    when cadillac went to the 390 the cal connell went up in horsepower to 325. i have the same engine as one of those twins. mine is pretty much the same except the chrome exhaust manifolds and rocker covers. it is fly wheel rear. the other engine is an earlier (331?) and flywhell forward. this is the one that jim has in the advertisement. i dont know what year they went fly wheel rear.

    i do know that i need a thermostat housing on mine, if anyone sees one let me know!!!

    mike

    I’m not sure which is more beautiful, the outside or the engineering that goes into a Riva build. While delivering one to northern Ohio that was shipped in from Italy to the port of Savannah, I had to crawl around inside the boat to take it all in. All the yacht flooring was rubber suspended and removable without tools. The rear cockpit had a hand shower with a through floor catch basin and drain pump, all wiring routed flat and fastened every 4 to 6 inches, no loose wiring just running “wild” thru the air, it was just incredible, I could go on and on.

    On the way through Cincinnati, a truck hauling an empty dumpster dropped it accidentally about 75 ft in front of me on I-75 n/bound while I’m pulling the Riva. Sparks are flying all over the road while this dumpster is grinding down the interstate at 60 mph. As I always do when towing, I left enough room between me and that truck/dumpster, to whip it over into the right lane and around the skidding metal monster. Cars were dodging left and right when I looked back in the mirror. Fortunately, I was closest and got around it without having to deal with the remaining traffic.

    • Texx

      Another entertaining story from the memory banks of Mr. Turbo, thanks for sharing it with us.

      We should start publishing a series of short classic boating stories under the title of “The Turbo Chronicles” – Like a Woody Boater version of Readers Digest…

      • Texx

        By the way – how would you ever explain to your insurance agent that you were hit by a dumpster that was speeding down the freeway at 60 MPH?

        • floyd r turbo

          Insurance? oh yes insurance, Carla runs from the Hagerty table when she sees me walking towards her, lol. just kidding. Ironically, it was just south of Lou Rauh’s old place Antique Boat Center, exit 8 Towne St but I was headed to the north shore.

  10. floyd r turbo

    “Look, officer, he (the dumpster) didn’t signal his lane change, cut me right off”.

    • Texx

      Officer says “Was it a vintage blue dumpster with a rusty lid or a modern green dumpster with a plastic lid?”
