The fast & sporty GTM 90 Transformer was developed to not only entertain, but also protect guests whatever the weather. The main aft deck and sun deck provide ample space for lounging open air, while the beach club, dining area and open-style galley with bar can be transformed with foldable bulwarks to allow the fresh sea breeze in. The striking exterior styling recalls the lines of modern supercars and a super-efficient hard chine hull delivers a top speed of 30+ knots with a range of 750 nm at 12 knots.

The first edition of the GTM 90 is being developed in collaboration with leading VIP-car tuner Klassen, with interior décor that mirrors the design of exclusive Klassen vans with different leathers, rich wood paneling and elegant LED courtesy lights. Klassen will also be responsible for all the exterior detailing, including leather supply, stitching and other special automotive design features.

key Features
  • Hard chine hull shape
    Hard chine hull shape
    Devised by leading Dutch naval architects, the GTM 90 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 GTM 90 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 GTM 90 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.
  • Curved Stabilizer Fins
    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 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.

  • XIR glass
    XIR glass
    The GTM 90 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.
