TECHNOHULL’s fastest ever boat is now just a few months away from hitting the water. Several units of the 38 Grand Sport are at the moulding stage, with delivery anticipated at the end of the summer. When they splash, they will set a new standard for the Greek RIB builder, and for the industry globally.

Pre-production models tested last year achieved a top speed of 103 knots over the ground, equivalent to 118mph. And yet the 38 Grand Sport is able to offer such performance in offshore conditions with astonishing stability and comfort, thanks to its ground-breaking Dynastream hull design.

Pure Sport

Packing two Mercury Verado 300/350/400/450hp outboards as options on its notched transom, or three 450hp motors in the super sport version, the 38GS offers serious power. Combined with its relatively narrow 3.1m beam, and a sharp semi wave-piercing bow, this boat achieves speeds that would have seemed unthinkable in the leisure market even a few years ago. 

A new deck layout featuring a sun pad at the bow and twin loungers aft, plus a streamlined, low profile helm console make this TECHNOHULL’s sportiest looking boat yet. The yard’s shock-mitigating bucket seats offer comfort at speed, or spec your favourite Shockwave or Ullman seat. Either way, the second-row seats feature fold-up bolsters and ergonomic footrests for guest comfort.

To complete the sports look, carefully-stitched Spradling fabrics come in a range of colours and styles.

Dynastream difference

TECHNOHULL is able to offer this sort of performance thanks to its patented Dynastream hull, which took five years to develop with a dedicated in-house team of naval architects. The design employs three distinct steps, to channel in air and provide lift, natural cushioning and stability at all speeds. This hyper-ventilated hull shape is 10-15 per cent more efficient than previous TECHNOHULL designs, offering lower fuel consumption for higher speeds.

Through a rigorous process of CFD simulation, scale and full-sized tank testing, and the expertise of the renowned Davidson Laboratory of New Jersey, TECHNOHULL has gained a thorough understanding of this technology. It is part of what allows the boat to plane at low speeds and achieve its eye-watering top speed.

Also, the super deep-V hull form gives the 38 Grand Sport true offshore capabilities. It deflects spray in even a heavy seaway and makes light of tough conditions – just as well considering the boat’s 220 nautical mile range. 


Just because this is a fast boat doesn’t make it a spartan one. TECHNOHULL has gone to some pains to ensure that the 38 Grand Sport offers real luxury. Besides the high-quality solid teak decking, there is also an electric toilet, external shower and the option of a snug cabin in the bow.

Choose between the open console or the elegant hardtop for better weatherproofing; add an extra canvas shade mounted on sleek, carbon poles. There is all-round LED courtesy lighting, too, and a bathing ladder which deploys and adjusts at the touch of a button.

TECHNOHULL claims the build quality is "superb" and a wide range of customisation requests can be delivered. Whether you want a unique look for your 38 Grand Sport, or to match it to a larger yacht, TECHNOHULL’s in-house designers can make it happen.
