A new class of cool

This avant-garde 50-metre superyacht is deliverable in just two years. With elegant yet sporty exterior styling, she packs a punch in terms of performance, aesthetics and onboard features. The combination of aluminium and Sealium alloys for the construction ensures a light, robust and easy to maintain vessel. When paired with a Hull Vane for maximum stability and efficiency, she boasts a top speed of 16 / 21 knots and transatlantic range. Onboard features include six luxurious guest cabins, two fixed balconies in the master stateroom, whisper-quiet propulsion, a touch-and-go helipad, and interior design by Claudio Pironi. She is the perfect yacht for cruising the Seven Seas in style.

key Features
  • Fast displacement hull form
    Fast displacement hull form
    Devised by leading Dutch naval architects, the GTT 165 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 maximizes 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 165 hull guarantees unparalleled comfort and safe operation for more than 25 years.
  • Robust full aluminium construction
    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 165 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.
  • Hull Vane
    Hull Vane
    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 and at anchor, while reducing both pitching and yawing motions.
  • CMC Stabilizer Fins
    CMC Stabilizer Fins
    CMC 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.
  • Transatlantic range
    Transatlantic range
    The GTT 165 has an ocean-going range of 5,000 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 165 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.
  • Touch & Go helipad
    Touch & Go helipad
    Helicopters are a convenient, time-saving and safe means of transportation. They are also a stylish way to welcome guests in style or explore uncharted locations. The GTT 165 offers a touch-and-go helipad platform with a maximum take-off weight 3,000 kg Eurocopter EC130 T2, AW 119, Bell 407 GXP).
  • Engine room cooling
    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.
  • Claudio Pironi for Dynamiq
    Claudio Pironi for Dynamiq
    Cult Italian design guru Claudio Pironi has studied the GTT 165 and has shared his unique vision of what the inside of a superyacht should look like. The client is free to choose this interior option, complete with bespoke, minimalist decisions, if they wish to maximize space and allow themselves to feel luxury regardless of where they choose to sail.
  • Main saloon fireplace
    Main saloon fireplace
    A real fireplace becomes a centrepiece and adds a cosy touch, especially when cruising early or later in the season when the evenings can be a bit chilly. They are completely safe and fully certified and rely on low-heat producing fuels such as ethanol.
  • High-end audio by Bowers & Wilkins
    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.
  • Owner’s stateroom with two fixed balconies
    Owner’s stateroom with two fixed balconies
    A standout feature aboard the GTT 165 are the two fixed balconies in the owner’s stateroom, which do not require any servicing or crew member to operate. Nor does the floor become an unsightly wall as with fold-down balconies. A fixed balcony means you can wake up and enjoy your morning coffee, sunbath in full privacy or read a newspaper close to the sea without delay.
  • XIR glass
    XIR glass
    The GTT 165 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.
