Dynamiq presents Stefania, the 41-metre gold Superyacht. This GTT135 was completed at the company’s shipyard in Massa, Tuscany, after 24 months of designing and construction. This golden beauty looks every inch a superstar!

Dobroserdov Design developed the elegant exterior of the aluminium superyacht. Her unique colour scheme of shiny gold and dark brown differentiates her from the other white superyacht in the ocean. Her reverse bow looks impressive and fresh and expresses the innovative, chic soul of Dynamiq yachts.  Just as important, she performs at the top of her class.

M/Y Stefania’s efficient fast-displacement hull was designed by Dutch naval architects Van Oossanen to give her minimal resistance and low fuel usage while still capable of high speeds. She uses as little as 50 litres of fuel per hour thanks to twin MAN V12 1650 engines.

  • Top Speed: 20 Knots
  • Range: 5000 Nautical Miles 
  • Cruising Speed: 10 Knots

With this range, the owners can enjoy two seasons during the year, the usual Med and Caribbean. Still, she is also capable of greater freedom when navigating remote locations like South-East Asia with no bunkering facilities. Stefania’s shallow draft of 1.8 metres makes her perfect for cruising the Bahamas’ remote cays and shoal waters.

The Hull Vane®, a patented fixed foil located under the stern of the boat, is one of Stefania’s distinguishing characteristics. This innovation results in a considerable reduction of pitch and hull resistance, allowing for the installation of smaller engines, lowering fuel costs and increasing range.

Sergei Dobroserdov founder of Dynamiq Says:

“Superyacht Stefania is the evolution of our full-aluminium Gran Turismo Transatlantic concept and represents everything you would expect in a medium-sized product from a boutique family shipyard: exclusive looks, advanced technologies and attention to detail”

“The basis of the GTT 135 is the lightweight full aluminium hull, but every element has been perfected, from the top-notch soundproofing components by Dutch experts Rubber Design, including a torque compensation system for the gearboxes, to the Bowers & Wilkins hi-end sound system. Dynamiq has even developed an exclusive pen with Montegrappa for the owner. The difference from our previous models is that the design and engineering has now been developed to the utmost degree. I am very happy with how the GTT135 looks: she’s modern and elegant with lots of design details and interesting elements. We are happy to state after the sea trials how her many technical innovations take performance and comfort to the next level.”
