After just over two years of engineering and construction, the 41-metre Dynamiq GTT135 has been launched from the Dynamiq shipyard in Massa, Tuscany, and looking every inch a superstar!

Stefania is the evolution of Dynamiq’s Gran Turismo Transatlantic (GTT) concept and represents everything you would expect in a 2021 top class superyacht from a boutique shipyard: exclusive looks, advanced technologies and attention to detail.

“We are very proud of this achievement, especially in these challenging COVID-19 times” says Dynamiq founder and CEO Sergei Dobroserdov. “This beautiful 41-metre superyacht looks impressive and fresh and expresses the innovative and chic soul of Dynamiq yachts. Just as importantly, she also performs at the top of her class with the latest technology on board such as the Hull Vane aft foil and a unique torque compensation system by Rubber Design, to name just a few. We’re sure she’ll be a source of exclusivity and pride for her owners, a family that didn’t follow the mainstream path and selected the Dynamiq GTT 135 because it’s the best vessel in her size range, together with her reverse bow, long waterline and master cabin located in the most comfortable place amidships on the lower deck. We are now completing the sea trials where our team and surveyors witnessed how her technical innovations took performance and comfort to the next level.”

Stefania is the result of a truly international collaboration with full engineering by Van Oossanen Naval Architects in the Netherlands, striking exterior design by Monaco-based studio Dobroserdov Design, and sophisticated interior styling by Giuseppina Arena in Miami. The exclusive colour palette of metallic gold and dark brown sets her apart from all the white yachts on the water.

Stefania’s efficient hull has a round-bilge shape creating a remarkably low resistance and low fuel consumption while still being capable of high speeds. She is equipped with twin MAN V12 1650 engines for a maximum speed of 20 knots with an ocean-going range of 3,000 miles at cruising speed, which means owners have the opportunity to enjoy two cruising seasons during the year (Med and Caribbean). There is also a greater freedom when navigating to remote destinations with no bunkering infrastructure as the yacht also has a shallow draft of 1.8 metres for cruising the cays and shoal waters of the Caribbean.

Meeting her modern owner’s active lifestyle, Stefania offers a balanced ratio of interior and exterior. The oversized pool on the main deck together with the beach club area leading to a bar allows guests to enjoy the en plein air lifestyle in port and at anchor. More privacy is offered on the 120m2 sundeck divided into two different zones including a jacuzzi, surrounded by large sunpads, two 75-inch TV screens and a bar unit. The al fresco dining area for 10 guests, and a convertible lounge area in the aft for enjoying life at sea and the panoramic views in style.

Stefania features Art Deco interiors with accommodation for 10 guests in five very spacious staterooms, including a full-beam master suite, all located on the lower deck in order to maximise motion comfort on board for owners and guests alike. The main saloon features full height windows with sliding doors in the dining area and customized furniture from Fendi Casa. Among other stand-out design features is the real fireplace, a centrepiece that adds a cosy touch when cruising early or later in the season when the evenings can be a bit chilly.

Dynamiq also joined forces with German VIP car outfitter Klassen to develop the optional “Wheelhouse by Klassen”, which comes with the same quality and style of Klassen VIP shuttle vans with sporty trim and high-end finishes.

Stefania is safe, comfortable and environmentally friendly vessel in accordance with strict RINA Commercial Class, Comfort and Green Star Plus notations and the latest REG manning standards.

After sea trials and delivery, the yacht will voyage to her home port of Monaco and will be available for charters through Arcon Yachts, who were also the build managers during construction.

The second hull of GTT 135 fast but highly efficient family cruisers is available for order with delivery summer 2022.


Dynamiq was founded in 2014 by experienced yacht broker and designer Sergei Dobroserdov, who assembled a ‘dream team’ of world thinkers, engineers and naval architects to turn the next-generation superyacht concept into reality.

“I simply believe we can propose something better that offers owners more choice: versatile yachts perfect for any occasion, whether it’s relaxing family cruising, vibrant deck parties and exploring the remotest destinations. Fast but with ocean-going range, easy to order and customise with top world brands,” says founder and CEO Sergei Dobroserdov.

Dynamiq is the first company in the superyacht industry to introduce an online configurator, allowing the yacht to be easily and transparently customised down to the last detail. Dynamiq unveiled its first launch, 39m Spring (ex-Jetsetter), at the 2016 Monaco Yacht Show to wide acclaim. The following project, the GTT 115 M/Y Jaaber, was developed in conjunction with the renowned design firm Studio F.A. Porsche and successfully unveiled at the 2017 MYS. GTT 135 (41m) Stefania will be delivered to her owner in Spring 2021. The latest addition to the Dynamiq fleet is the GTM 90 Beach Club and new Global series of long-range explorer yachts designed on the EPIQ platform of Efficiency, Performance, Innovation and Quality.
