Powering a Porsche

Taking the spirit of highperformance sports car styling to the high sea.

Dynamiq has recently launched its latest project, the Studio F.A. Porsche-designed Dynamiq GTT 115.

The luxury, 35-metre superyacht features a hybrid power plant, REINTJES’ FORTJES 5000 pod system, and a complete set of CFD-optimised, CNC-machined CJR propellers for optimum performance and minimized noise and vibration.

The launch, which took place in Viareggio, Italy, heard Dynamiq CEO, Sergei Dobroserdov, describe the GTT 115 as “the culmination of a long process of design and development to introduce a new kind of superyacht to the market.” He wasn’t exaggerating either. The GTT 115 has the unique honour of being the first superyacht designed – both inside and out – by Studio F.A. Porsche, with the objective of “taking the spirit of high-performance sports car styling to the high seas,” according to Roland Heiler, CEO of Studio F.A. Porsche.

However, this isn’t a case of style over substance. The all-aluminium yacht is built to RINA classification and is MCA compliant, with her naval architecture provided by the respected Dutch studio, Vripack. Power is delivered by a pair of 1,650hp MAN V12 diesel engines, twinned to FORTJES 5000 pod drives and three variable-speed generators for a top speed of 21 knots and a maximum range of 3,400 nautical miles.

The FORTJES 5000 pod drives are designed for performance but also offer greater efficiency than any system using conventional shafts and propellers. Their positioning, situated outside the hull, also means reduced noise and vibration, as well as lower emissions. In the case of the GTT 115, the pods use contra-rotating CJR-designed propellers linked via a compact gearbox to the main engines – reducing engine room space requirements by nearly 18%, which means more accommodation space for the owners and their guests.

“This is precisely the type of project we are becoming known for,” commented Mark Russell, CJR managing director. “Our investment in some of the industry’s most advanced CFD analysis software means that we are uniquely positioned to maximize the benefits of this type of drive system.

“The complexities of contra-rotating propellers means finding the optimal position for the props is vital, and you simply can’t do that without the use of computational fluid dynamics and the experience required to act on the results. For this project alone, we tested 30 different iterative designs to ensure maximum performance and efficiency, with high manoeuvrability at low speeds and improved stability at high speeds. We can do this faster and more cost-effectively than anyone else in the market, thanks to our highly-specialist team and in-house super-computer,” Russell added.

In addition to the fully optimised propulsion system, the GTT 115 features a vertical prow and an exclusive electric stabilization system, which uses four cutting-edge electric stabilisers and four interceptors and, as a result, reduces roll by up to 85% while enhancing stability and course keeping. At anchor, four fins with a large total area reduce roll by up to 60%. Plus, with no hydraulic systems running through the yacht, there is no risk of interior damage following a hydraulic system failure.

Other key features include a spa pool on the upper deck, which is situated just forward of the shaded al fresco dining area. Guest accommodation is all below deck with a configuration choice of three or four cabins, as well as a spacious light-filled saloon. The Porsche-influenced touches continue throughout the vessel and even include Pepita dogtooth deck cushions, similar to those found in the latest Porsche 911 R edition sports car.
