The Tuscan shipyard, Benetti, is currently attending the 2013 Cannes International Boat Show, presenting a third generation of fast yachts, rounding out the already extensive range of products. This presently comprises Class Range, semi-custom displacement vessels with 6 models from 93′ to 145′, as well as Custom, mega-yachts starting at 45 metres.
The new Fast Displacement line of composite yachts built by Benetti in the Viareggio boatyard already includes two models: the F-140’ yacht, introduced last year, and the brand new F-125’ yacht, which is making her debut at Cannes 2013.
With this new line, the boatyard intends to tap into a strong and as yet relatively unexplored market in semicustom super yachts with a sporty spirit. These are vessels characterised by their versatility, speed (when called for), but which are also extremely comfortable in displacement mode and highly efficient at any speed. Their dynamism perfectly unites with the sheer pleasure of on board living, and the construction quality and maximum customisation which Benetti is known for.
Benetti CEO Vincenzo Poerio says, “Many of our clients have requested faster, more versatile, and efficient boats, while maintaining the same level of comfort and customisation found in our existing yachts. The new Fast Displacement line is designed precisely in response to these requests, and it rounds out our current offering in the Class Range. We haven’t just created a new series; we have invested time and resources – combining the Benetti’s 140-years of experience in super yachts with the technological knowhow of Azimut Benetti Group – to create a new way of heading out to sea.”
The two Fast Displacement models were developed by Benetti in collaboration with the Azimut Benetti Group Research Centre, which has designed an extremely innovative hull geometry exclusively for the new range. The Fast Displacement yachts are equipped with a revolutionary new D2P_Displacement to Planing® hull which unites sportiness and the performance of a planing hull with the comfort and quiet of a displacement hull.
The D2P® hull has been coupled with a wave piercer bulbous at bow, a combination which affords increased cruising efficiency (less resistance to forward motion) of up to 30% compared to a conventional hull.
The design of this new hull was carried out using a series of CFD (Computational Fluid Dynamic) simulations to define the best possible geometries. This was followed by extensive tank testing to verify the computer simulations and validate the hull geometries and associated appendages. After an initial “theoretical” phase of developing the hull shape based on preliminary design data and layout (sizes, general plan, and design specifications), the design process then involved a hull optimising phase using CFD (Computational Fluid Dynamic) simulations.
The development of the hull shapes was quickly followed by tank testing (at the Brodarski Institute in Zagreb) during which important hull components were optimised and validated including the bow wave piercer and the stern tunnel thrusters. The tank testing also included hull auto propulsion tests on all the appendages, to verify the final propulsion efficiency and associated speed performance.
The D2P® hull is equipped with a wave piercer, enabling the new Fast Displacement series to reach higher speeds without engine strain, or to cruise in displacement mode at an economical speed with a much greater range. The hull has been optimised for the entire range of most frequently used speeds, including displacement modes from 10-12 knots with increased range as well as cruising speeds and maximum speed of 22 knots in semi-displacement mode.
Compared to the traditional semi-displacement hull, the new D2P® hull offers countless advantages:
• Increased efficiency at all speeds and therefore maximum flexibility of use
• Lower fuel consumption and therefore greater range
• Higher cruising speed and therefore reduced transfer times
• Significant reduction in pitch and slamming and therefore increased cruising comfort
Today, the new Fast Displacement Class Range includes two new models, the F-125’ and the F-140’. This is a clear sign that Benetti has entered the new market of semi-custom fast yachts and that it is rounding out its range to satisfy even the most demanding boatowners, ever respectful of the values which have distinguished the Benetti boatyard over its 140-year history: innovative technology, design, customer service, and construction excellence.
