Perseus^3 is the second hull in the 60-m sailing yacht series produced by the Perini Navi Group, to be followed by a third hull that has already been sold and will be launched in 2017, and a fourth currently under construction on spec. In the context of Perini Navi’s production, ‘series’ has a very specific meaning that differs from the concept of a series for many other yachting businesses. Here, ‘series’ means a basic naval architecture design that is interpreted differently for each individual vessel in order to offer owners exactly what they want. This does not just mean an unchanging hull and superstructure, with compartmentation and fittings chosen by the owner; instead, clients are offered the opportunity to create a sailing yacht that meets their needs as sailing enthusiasts in every detail on a single platform. The 60 m series is a good example of this fully custom philosophy on an unchanging platform. There are many differences between the first vessels in the 60 m series, Seahawk, and Perseus^3, starting with technical aspects. These range from the obvious differences in the sail plans to the equally apparent differences in the choices that make Perseus^3 a yacht designed for superyacht regatta yacht regattas as well as cruises in the utmost comfort. If we add to these basic characteristics the substantial design effort made by the Perini Navi Group in its search for solutions to facilitate manoeuvring with similar sail plans, making it not just simpler for the crew but also safer and quicker, we can get an idea of the huge amount of work done by the Italian shipyard to achieve results that set new standards. Let’s start with what makes Perseus^3 different from the other yachts in the series, such as the first hull, Seahawk, which was awarded international prizes for her design. On this previous sailing yacht, the Perini Navi Group introduced some key innovations, such as the new furlers coupled with large winches specially made to offer the speed and power required for rapid, safe manoeuvring. On Perseus^3, these elements have been improved even further, and the forces in play are different, since Seahawk is ketch rigged while Perseus^3 is a magnificent sloop, with further significant technical innovations in her rigging. The Owner of Perseus^3 clearly doesn’t like merely participating in regattas, he likes to win them, and has therefore chosen cutting-edge solutions that allow the yacht to manoeuvre extremely quickly, with a single 75 m high carbon mast dressed with Carbon Rigging and PBO Headstays. This choice of lighter rigging and the resulting use of carbon made it possible to limit mass high up, resulting in the centre of gravity being brought down. The benefit generated by this choice is not so much a reduction in general weight but rather a major increase in the righting moment, resulting in greater stability. However, efficient sailing has also been achieved through by repositioning the centerboard and its casing as well as the presence of the twin rudder element, as well as the presence of a double rudder, meaning that the surface under water and therefore drag are further reduced. All these adjustments are clearly intended to increase performance, but not just that, as thanks to the sloop rigging the deck remains a comfortable, safe place for the Owner and guests even in regatta conditions, since the aft deck -dedicated to Reacher or Gennaker sheet trimming – ensures separation of the relaxation areas in the aft cockpit and on the flying bridge. Talking about Perseus^3 necessarily entails looking at issues of advanced technology applied to the management of a modern, highly efficient yacht like this one. Both the sail handling gear and the powerful rigging intended to manage a sail plan designed and manufactured exclusively for this yacht are controlled by a complex integrated system that allows the crew to carry out fast, simplified manoeuvring. The manoeuvring speed is another unique element on this yacht, the result of the applied research that the Perini Navi Group constantly carries out in this field. All of this has resulted in systems for furling, trimming and sail handling that offer very fast times. This has been achieved with the adoption of captive reel winches that are not visible on the boat as they are enclosed below deck, and which can handle the speed and power necessary for such a sail plan. Given the powerful sail plan developed by Doyle for Perseus^3, the powers in play and the forces that need to be managed are undoubtedly so great that developing specific solutions was unavoidable. We asked Burak Akgül, Sales, Marketing & Design Director of the Perini Navi Group, to tell us about these technical characteristics and all the technology on Perseus^3:“The owner of Perseus^3 is someone who doesn’t merely want to participate in regattas, he wants to win them. But he wants to do it with a sailing yacht capable of travelling around the world in the utmost comfort and safety. The initial theme was therefore complex, requiring the development of numerous solutions that could on the one hand reduce the weight to ensure suitable performance even in light winds, and on the other ensure the most efficient sail handling handling possible in terms of speed and safety. To optimise performance, we also redesigned the keel centre based on a different sail centre, as this was a sloop rather than a ketch like the first hull and the third which is currently under construction. In practice, we moved the keel centre forward one frame and the resulting balancing was very important. This solution made the hull even more efficient in tackling a moderate sea, which was confirmed by the crew even after a journey from Malta when they encountered a moderate sea with a headwind at a speed of 25-30 knots. The pitch of the hull is negligible and comfort for the crew is always excellent, even though the crew quarters are forward. In terms of the results achieved with the combination of these technical elements, I must say that we are very pleased because the boat handles very well in light winds and also pulls hard, especially in regattas. Just think that with a true wind speed of 13 knots, we were able to sail upwind at an angle of less than 40° at a speed of 13 knots. For a 60-m sailing yacht, these figures are certainly very positive. We also carried out other tests during the recent Palma de Mallorca regattas, and with a true wind speed of 8 knots we sailed at 9 knots making use of the apparent wind. I repeat, with a 60-m vessel and nearly 550 tonnes of displacement this is a great result. The sail plan of this vessel has naturally been developed to guarantee this level of performance, with the collaboration of Doyle, which created the sails specially for Perseus^3, some of which are the largest sails ever built in the world. Just consider that the A2 with a surface area of 2,200 m2. In spite of this imposing and more importantly very powerful sail plan, the balance achieved partly with modifications to the underwater body is extraordinary and ensures that the helmsman can always have everything under control in the most effective way. For some years now, we have also been developing an electronic system that simulates the rudder’s resistance to allow the helmsman to have realistic feedback and tactile sensation in real time. On Perseus^3, we have also introduced a control system for the twin rudder that further optimises manoeuvrability in various operating modes. The vessel’s navigation is impeccable, something we have seen partly through analyses of various wind conditions, where we obtained very limited leeway values and genuinely extraordinary course stability which obviously derives from the balance obtained with the various solutions I have described. The speed with which the rigging can be managed must also be added to all this, with systems for handling the lines, halyards and all the rigging that allow this boat to be handled faster than ever before. We are very proud of the results we have achieved, because the forces and powers in play are very high but we were able to make a series of gybes during the Palma de Mallorca regatta at a speed that unarguably demonstrated the effectiveness of the whole system. The gear we have developed has proven to be amply oversized, affording a high level of safety particularly in view of the cruises the Owner wants to tackle in the near future. The yacht is due to make a cruise to the Pacific around Cape Horn in the near future, so safety is a key element as it should be for a boat like this one, even though we’re talking about a yacht that seeks to match the maxi yachts in international regattas.” First and foremost she is a boat designed for cruising, offering complete comfort inside and out. There are numerous careful details typical of a cruising yacht, such as the large guest cabins all located to ensure the right level of privacy, the relaxation areas fitted out to be used in any external conditions and offering entertainment systems and suitable space, luxurious interiors, a forward Jacuzzi on the main deck with a water recovery system to limit waste, and countless other details to ensure that the Owner and guests have an enjoyable stay on board even during very demanding voyages.
