TRIBUTE TO 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.

​

HULL

Drawn by the famous Dutch naval architects Vripack, 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 in the hull, which translates into a far more comfortable motion when sailing. The avant-garde 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.

HULL VANE®

The Hull Vane® is a patented fixed foil located below the stern of a ship. 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 much smaller engines, fuel savings and longer range. The Hull Vane® also improves stability under way and at anchor, while reducing both pitching and yawing motions.

​

PROPULSION

Fortjes pods are much more efficient than any system using conventional shafts and propellers. Their positioning outside the hull also means greatly reduced noise and vibration levels, as well as lower emissions. The pods use counter-rotating propellers linked via a compact gearbox to the main engines, reducing engine room space requirements by nearly 18%, which means more accommodation for you and your guests. Built in Germany, Fortjes pods are the perfect compliment to the efficient GTT 115 hull form.

​

STABILISATION SYSTEM

Swedish leading specialists Humphree created a custom stabilisation system using 4 cutting-edge electric stabilisers and 4 interceptors. The very efficient system underway reduces roll by up to 85%, while enhancing stability and course keeping. At anchor, 4 fins with a large total area cut roll by up to 60%. Electric stabilisers are far quieter, more reactive, take up less space and are more power efficient than their hydraulic counterparts. With no hydraulic systems running through the yacht, there is also no risk of interior damage following a hydraulic system failure.

​

HYBRID POWER PLANT (OPTION)

With the main engines switched off, the generators power two ultra-compact 20 kW electric motors allowing the yacht to reach 6 knots in complete silence for an unlimited period of time.

​

GLASS

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 40%. 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.

​

SUNDECK

The huge, 95-sq/m (1,022-sq/ft) sundeck is bigger than those found on much larger yachts, and has been created to allow maximum functionality. It has been carefully designed with four versatile zones: an aft sunbathing area; an alfresco dining area with 75-inch home theatre screen; a bar and barbecue zone; and a forward pool with sunbathing area. Deck furniture is Minotti outdoor collection, while deck cushions are fabric upholstered with a classic Pepita houndstooth pattern similar to the latest Porsche 991 R edition.

​

FORWARD GARAGE

Unusual for a yacht of this size, the GTT115 has a forward garage that allows the deployment of a 15-foot tender and jet-ski at any time, even when docked in port. It also provides great storage capacity far away from the guest areas.
