A bespoke and beautiful yacht designed in collaboration with Studio F.A. Porsche, the 35.5 m (115’) GTT 115 blends comfortable high-speed cruising with transatlantic range. Featuring hybrid propulsion, Hull Vane and an exclusively designed four-fin stabilisation system, she embraces advanced technology for super-efficient performance and top cruising comfort. Spacious guest areas with generous ceiling heights of 2.15 m (7’ 1’’), as well as a massive and versatile sundeck, create a very special onboard experience. Only seven editions of the GTT 115 will be built, making her a truly exclusive collector’s item.
The price for the GTT 115 starts at €12,500,000 (excluding all options, taxes and charges). Call us today to configure your very own version!
Fast Displacement Hull Form
Devised by the famous Dutch naval architects Van Oossanen, the GTT 115 unique hull features a round-bilge shape for remarkably low resistance and low fuel consumption while still being capable of high speeds. The design decreases vertical accelerations of the hull, which translates into a far more comfortable motion when sailing. The bow shape with a vertical stem maximises the waterline length, enhancing performance even more. To keep spray levels low, an integrated spray rail deflects water hitting the bow area. Built entirely from marine grade aluminium, the GTT 115 hull guarantees unparalleled comfort and safe operation for more than 25 years.
Robust Full Aluminium Construction
Certified marine-grade 5083 aluminium and stronger 5383 Sealium, a lightweight alloy that weighs three times less than steel, is used for Dynamiq GTT 115 hull and superstructure. A lighter hull provides better performance, shallower draft, lower fuel consumption. Another benefit is that aluminium guarantees a stiff, robust and vibration-free vessel that is very comfortable and behaves well in a heavy swell or choppy seas. The strength-to-weight ratio of aluminium is equivalent to that of steel and there is much less risk of serious damage in case of a collision than with a fibreglass hull.
The Hull Vane® is a patented fixed foil located under the stern of the yacht. Developed by renowned Dutch naval architects Van Oossanen it influences the stern wave pattern and creates hydrodynamic lift, which is partially oriented forward. This innovation leads to significant reduction of the hull's resistance, which in turn enables the installation of smaller engines, fuel savings and longer range. The Hull Vane® also improves stability under way reducing both pitching and yawing motions.
Curved Stabilizer Fins
Vector Fins stabilizers dramatically reduce roll as well as undesired yaw and sway motions caused by active fins. Their vertical concave shape creates a net force direction, both in cruising and at-anchor modes, so the work is more up-down instead of side-to-side. By changing the net force angle, this also increases the leverage arm around the boat’s rolling point, further increasing the physical forces that work on the boat to reduce roll. This provides more efficient stabilization per fin size, which means that drag and power consumption are less than with other fins offering comparable roll reduction.
The GTT 115 has an ocean-going range of 3,400 miles at 10 knots and is perfectly equipped for long-range cruises, which means owners have the opportunity to enjoy two seasons during the year (Med and Caribbean) and greater freedom navigating remote locations with no bunkering infrastructure. GTT 115 is equipped with high-capacity Miele marine fridges and freezers, cold garbage stores, separate laundry facilities and plenty of storage space. Generous fresh-water tanks and powerful water-makers allow guests to spend long periods of time sea in complete comfort.
Engine Room Cooling
The engine room cooling offers two main benefits: on the one hand it cools down the ER quicker on arrival in port or anchorage without having the blowers running full power for an hour; and on the other hand, it keeps the ER at a comfortable and steady temperature while at anchor to preserve electrical equipment. Overall, the benefit is reduced noise as there is no need to have the blowers running when the yacht is static, and the temperature cooling in the engine room makes it a more comfortable environment to work in. A long-term benefit is that it extends the longevity of all the equipment and especially the electronic parts.
Design by F.A. Porsche
Studio F.A. Porsche created exclusive exteriors with the Porsche DNA. GTT 115 features the carmaker’s signature elements like Targa-style mullions or transom in line with the futuristic Mission E concept study. Available in Carrara White, Rhodium Silver, Chalk or special Monte-Carlo Blue from Porsche line exterior colours.
High-end Audio by Bowers & Wilkins
Dynamiq has partnered with iconic British sound maker Bowers & Wilkins to deliver pristine sound to its discerning customers. All luxury spaces and each guest cabin will be carefully analysed and studied by experts to ensure the ideal positioning of the speaker systems to have the best possible sound expertise on board.
The GTT 115 features next-generation laminated XIR glass that allows maximum light transmission, while keeping solar heat gain at bay. Harmful UV rays are almost completely blocked, and heat transmission reduced by 60%. The result is an interior that offers the wide panoramas of large windows without the penalty of heat build-up. This means significantly reduced air-conditioning loads and therefore lower running costs. The glass manufacturer is Isoclima, an Italian high-tech company that also supplies glass for luxury automobiles such as Bentley, McLaren, Mercedes and BMW.
