Twin Disc Pacific has been appointed the Exclusive Distributor for the innovative Seatorque Marine Propulsion Systems. The enclosed shaft system is a major feature on the new Riviera 68 and 72 Sports Motor Yacht set for a 2017 Sydney International Boat Show debut.
Unlike traditional diesel inboard boats that require shaft alignment, the Seatorque system uses a coupling or bolt-on shaft system called a Boss for short. The totally enclosed, oil-filled, self-contained, shaft and thrust bearing assembly is supplied as a complete unit from transmission output coupling to propeller end. The shaft system uses rubber mounts and attaches to the hull structure, with a flexible connection to the propulsion engine. This ensures shaft-line noise and vibration are eliminated at the source…
Making boats and making boats better are passions that have driven Peter and Jana Stolper for more than 30 years.
Today this power couple, owners of Seatorque in Stuart, has established a worldwide reputation for designing and manufacturing ultimate quality products for large high-end yachts (50 to 200 feet in length). The Stolpers’ array of inventions and innovations for boat builders includes products that boost performance, cost less in the long run and have think-outside-the-box properties that consistently grab the international yacht-building community’s attention and respect…
Even though up to 95% of their business is international exports, Jana and Peter Stolper consider Stuart a perfect place to center their business, Seatorue Control Systems. But then, that’s that happens when you move from Rhode Island.
Adastra super yacht is a one-of-a-kind aquatic marvel: In the world of boating, there are yachts, super yachts, and then there’s the Adastra, a massive, custom built masterpiece of engineering that looks more like a spacecraft from Star Wars than an actual vehicle.
ADASTRA SuperYacht – Propulsion by SEATORQUE. Adastra is equipped with an ST-300 Seatorque Enclosed Shaft and Thrust Bearing Package. The entire driveline is an impressive 33ft (10m) in length.
Chris Conklin on watch on Tony Fleming’s new 65. VENTURE II incorporates several new, technologically advanced systems.
When Fleming Yachts asked if I’d contribute to Venturer magazine again I was delighted to do so, under one condition. I insisted upon sea trialing the components about which they’d asked me to write. That request was granted while I made a passage from Stornoway in northern Scotland to Reykjavik, Iceland, aboard VENTURE II, Tony Fleming’s personal Fleming 65.
Clever people who take the celebrated “simple approach” to problem-solving often stray far from the conventional way of doing things.
“Is it hard to argue with tradition? Not really,” quips marine manufacturer, and former America’s Cup racer, Peter Stolper. “Especially when that tradition is an old technology that’s had no real development for 200 years!” Peter and his wife Jana recently founded a company to solve a problem that has plagued boatbuilders since the first propeller shaft was tentatively poked through a hull.
If you plan on building an 80-foot sportfisherman that’s capable of more than 40 mph, you’d better build her strong. Donzi Yachts believes it’s done just that. Bob Roscioli founded the company 22 years ago, purchasing the rights to the Donzi name from the legendary Dick Genth. Although Donzi Yachts by Roscioli remains a separate company from Donzi Marine—its boats are all over 50 feet, while Donzi Marine’s are considerably smaller—and its strength is its traditional way of building. According to Roscioli, the construction process for the R-80 is similar to the boats he originally built. Although some of the methods may seem like overkill nowadays, Roscioli’s simple declaration can’t be argued with: “It’s tough,” he says.
Already successful in the US, Seatorque is looking to conquer the global market with a New Zealand designed new-build about to be completed in Africa.
Is it hard to argue with tradition?
“Not really,” quips marine manufacturer and former America’s Cup racer Peter Stolper. “Especially when that tradition is an old technology that’s had no real development for 200 years.”
