“The R35 is a rare mix of extreme elegance and technology. Often design is a triumph of beauty over function or function over beauty. Princess has been able to develop a technologically game changing yacht that is also stunningly beautiful. It is in every way a new experience, yet also instantly recognisable as a Princess.”
Antony Sheriff, Executive Chairman of Princess Yachts.
Introduction
The R35 is a genuinely innovative and revolutionary yacht borne of a desire to combine all of Princess’s renowned design and quality strengths with new technologies, materials, and engineering and design partnerships. As the world’s first R Class performance sports yacht, the R35 will make its debut at the Cannes Yachting Festival in September 2018.
To deliver a truly game-changing sports yacht, Princess has teamed up with the world’s finest design and technology partners to ensure the R35 delivers a new, intoxicating experience. It will enthral Princess loyalists and engage new customers at first sight and first ride. The inspiration for the R35 came from many sources, but focussed on one clear goal: how could Princess deliver a beautiful and elegant yacht that re-defines dynamic performance?
A key differentiator is Princess’s unique collaboration with BAR Technologies – the British company behind Britain’s attempt to win back the America’s Cup – that allows the R35 to utilise the benefits of foiling technologies to take performance, handling and efficiency to new heights. What followed was a meeting of minds, as Princess challenged BAR Technologies to transfer their racing knowledge into the motor yacht industry. Princess wanted to raise the bar: was it possible, using a dynamic foil system, to dramatically improve stability and seakeeping on the R35, whilst reducing drag by up to 30 per cent?
The result is the ingenious Princess Active Foil System (AFS). Twin moving foils beneath the waterline provide improved dynamic stability, raise the performance bar and increase efficiency. AFS does not elevate the hull above the waterline like the America’s Cup sailing yachts. Instead, it uses the lift to dynamically adjust the heel and running angle, optimising ride and comfort. Incorporated in a small, dynamic sports yacht like the R35, the benefits of AFS are immediately and dramatically obvious.
Princess found further inspiration working together with iconic styling house Pininfarina, responsible for some of the world’s most beautiful motor cars. There is a historic and intrinsic link between boat and car design that the Italian company inherently understands – the step changes in automotive design in the 1930s and 50s was inspired by the sweeping curves and graceful lines of the boats of that period. As a result, the R35 looks sculpted, elegant, dramatic, and as breathtaking at speed as it does at a standstill. A testament to the designers who created it.
Vitally, the R35 also builds on Princess Yachts’ leading market position and loyal customer base. It points to an even brighter future for the world’s leading yacht builder, engaging new customers
and presenting new technologies and design language that will be rolled out across the range in coming years.
Having delivered record financial results in 2017, with their highest ever annual sales performance, a return to profitability, and over $1bn of advanced orders, the R35 rides the waves of recent successes and will be the first of six new launches in the second half of the year that are set to help Princess deliver even stronger financial results for 2018.
America’s Cup inspiration from Ben Ainslie Racing Technologies
Princess’s innovation partner on the R35 is BAR Technologies – the nautical experts behind Britain’s bid to win the America’s Cup.
Known as the Formula 1 of sailing, the America’s Cup inspires its competitors to design the most advanced boats on the water. Where wings harness the power of air flow in Formula 1, foiling
techniques have driven America’s Cup racing boats to reach incredible speeds. It has put the world’s oldest sporting trophy back in the global spotlight and illuminated just what is possible onwater.
As with Formula 1 and the automotive industry that supports it, and just as the ‘race-to-road’ concept sets the standard in developing sportscars, technology flows down to the customer. This
long-held motor racing principle is now happening on water.
BAR Technologies worked closely with Princess’s development team in Plymouth in the goal to make game-changing improvements to the potential handling, grip and seakeeping of Princess’s
future yachts. The result on the R35 is a new performance benchmark defined by hydrodynamic innovation via the unique Princess Active Foil System (AFS).
“We wanted to bring America’s Cup foiling prowess into the luxury yacht market in an entirely new way. But the brief wasn’t ‘how can we include foils’ – rather it was ‘how can we build a hull that is noticeably more efficient, stable and faster.”
Paul MacKenzie, Product Development Director at Princess Yachts.
Princess Active Foil System
Hydrodynamics are the new fast forward in yachting, and the America’s Cup technology encapsulated in the Princess Active Foil System (AFS) underpins the R35’s fluid, fast and unflappable behaviour across the water: the catalyst for a leap forward in boat design.
The Princess AFS is a unique design that helps deliver not just the fastest Princess ride ever, but also the most exhilarating yacht ride. AFS engages twin carbon-fibre custom-engineered foils
beneath the waterline to reduce drag and provide unrivalled stability – it also helps the R35 achieve fuel efficiency savings of almost 30 per cent at cruising speed.
The port and starboard foils can adjust independently of each other by +/- 5 degrees with the foil positioning being calculated automatically by an onboard computer that takes input from pitch, roll and heave acceleration from a high resolution IMU (inertial measurement unit), boat speed, engine revs, steering input and user selected modes. The optimal foil position is computed 100 times per second with almost instant foil response as required to give the boat exceptional comfort and stability. Unlike other foil technologies, AFS does not lift the R35 out of the water. Instead, it adjusts the heel angle and attitude of the boat ensuring the most effective contact area at the bow at any speed for stable travel and extreme levels of grip when cornering to optimise ride comfort and efficiency.
A mode selector at the helm allows the pilot to choose between Optimal, Sport and Rough weather control algorithms which adjust the attitude and responsiveness of the foils to suit the pilot’s wishes.
But what does that mean when out on the water?
The R35 has a raft of technologically advanced features that seamlessly combine high performance and comfort. Auto-comfort and auto-sport settings take the strain out of piloting the boat, while independent roll and pitch control can be adjusted manually or automatically, depending on the helmsman’s choice.
AFS means the boat is working with the sea rather than battling against it, providing a new, on the water experience. The foiling system controls the attitude of the boat regardless of sea conditions
or hard acceleration, actively keeping the R35 steady, even in a straight line. If required, AFS also compensates when the boat is banking left or right to offer a more balanced ride when cruising or
an exhilarating G-force-induced heave never before experienced in sports yachts.
Carbon closes the innovation loop
Core to the effective installation of the AFS system was a rigid, predictable and lightweight hull. A full carbon fibre monocoque structure was the only option to fully optimise the potential for Princess’s revolutionary R35 design: the first time this has been seen in a Princess, and any series boat of this size and price point.
Carbon fibre offers a 15-20 per cent weight saving over the more conventional glass fibre, but that wasn’t enough of a technology leap for Princess. The design engineering team therefore selected
a resin film infusion, rather than resin infusion, which allows for much more efficient use of resin and a subsequent weight saving of 25 per cent over glass fibre.
For a high performance boat, weight is key, so Princess also avoided using a gel coat on the R35, shaving a further 300kg off the weight. The system is called Sprint and has a surface film equivalent to a gel coat, helping to push the boundaries of process and design.
Carbon is now key to Princess’s future, so the company has already installed a state-of-the-art carbon fibre production unit at its Plymouth headquarters. The investment makes Princess the first
luxury yacht manufacturer to introduce full carbon fibre boat construction on a volume assembly line.
“We decided to use carbon fibre to build the R35 because our boats are getting bigger and stability is very important. We wanted to bring carbon fibre into the business in a more extensive way and thought the R35 was a great technology developer to further develop our yacht building skills.”
Paul MacKenzie, Product Development Director at Princess Yachts.
Lightweight, powerful and efficient engines
To fully exploit the carbon hull, the AFS system, and their combined performance potential, Princess has employed a state-of-the-art petrol engine. Robust, safe, compact and highly efficient,
the engines provide a tangible boost in performance and excitement: another indication of Princess’s ambition to challenge perceptions at every turn.
The smooth delivery of power in the R35 comes from twin Volvo Penta 430 horsepower V8 petrol engines. The engines are all aluminium and feature direct injection, variable valve timing and fully CNC machined intake and exhaust ports to provide exceptional levels of torque and responsiveness that safely power the R35 to an exhilarating 50 knots: the fastest-ever Princess.
A beneficial power/size to weight ratio plus the efficiency of modern petrol engines made them the best choice and give the R35 its exhilarating top speed and responsive performance at all speeds – the boat will happily cruise efficiently at 25 knots.
The 6.2-litre 430 is the most powerful of the next generation of Volvo Penta petrol engines, producing 14 per cent faster acceleration and ten per cent improved fuel economy over the previous model. It incorporates a combination of technical features perfectly suited to helping helmsmen make the most of the R35’s technology. Among these are closed-loop freshwater cooling, with no internal parts exposed to raw or salt water, and wideband oxygen sensors that optimise the engine for varying fuel quality and reduce carbon monoxide emissions by 95 per cent.
“We challenged the perception that limits of performance had been reached for yachts – that there were no more tangible gains in the battle between stability and speed. Just like a race team, we looked for the competitive edge, the last tenth, the supposedly impossible performance gain. And our vision and ambition changed that perception and created the R35.”
Antony Sheriff, Executive Chairman, Princess Yachts
Design and style from the heart and head
Beauty and form in tune with technology define the R35 looks and performance.
“This ‘revolution’ started with a simple idea: to speak to people we haven’t spoken to before and to engage a totally new type of customer, whilst exciting and delivering a true Princess to our existing family of owners and fans. We also intended to take a radical communications step towards ‘cool’. To bring this product to market we wanted to explore the boundaries of our comfort zone and leap across with conviction. We’ve designed, built and delivered 17,000 yachts since we started in 1965, and that confidence was the basis for the R/evolution. That confidence is found in the Steve McQueen or Mohammad Ali style of cool, and pushed us to explore ideas such as Manga and Animé to bring this product to life.”
Kiran Haslam, Director of Marketing at Princess Yachts.
Pininfarina – An Iconic Design Partner
Another key new partner for the R35 and Princess Yachts is legendary Italian styling house Pininfarina.
Based in Turin, the car design capital of Italy, the Italian coachbuilder has been responsible for shaping some of the world’s most exceptional cars for almost 90 years, including nearly every Ferrari ever created. Theirs is a long-established name forever synonymous with automotive classics, but Pininfarina has also put its considerable talents into designing products as varied as private jets, hydrogen powered supercars, locomotives and even the 2006 Olympic torch.
Pininfarina’s iconic designs are, in the words of founder Battista ‘Pinin’ Farina, “an agreement of lines, a sense of proportion, simplicity and harmony”. Yet this simple explanation of design masks
the complexity that goes into defining a new innovative product that needs to be instantly recognisable to the cognoscenti yet stand apart visually from the competition. As a result, more than 100 concept drawings were created by Pininfarina and the Princess Design Studio before a final theme was selected.
The exciting collaboration with Pininfarina has created a performance yacht of instant visual style, drama, simplicity and elegance. The R35 may be an all-new boat but it has the head-turning look
of a thoroughbred and clearly communicates its performance potential through its beautiful surfacing, functional air passages and strong, defining character lines.
“We wanted to push the boundaries of what Princess – and our customers – understand our current design styling language to be. The R35 had to feel fluid, elegant and achingly beautiful. And make you glance back at it after 10 seconds every time you step ashore. Above all else it needed to be recognisable and believable as the next generation of Princess yachts.”
Andy Lawrence, Head of Design at Princess Yachts.
Design and technology in harmony
Form and function unite in the R35’s carbon fibre hull, which has been sculpted out on both sides with Princess’s side air blade design. This adds visual drama and manages air flow and vortices to direct and supress spray that could normally come back into the boat. Computational Fluid Dynamics (CFD) analysis was key to channelling airflow: CFD uses supercomputers to provide detailed analytics of fluid flow to solve design problems and is a mainstay of supercar aerodynamic engineering.
And to create the R35’s symphony of curves and edges, extensive development of the lightweight, carbon-fibre hull required 3D modelling software to study the clarity, movement of light and reflections across all the R35’s surfaces. This was especially important as the hull and deck are painted in highly reflective metallic colours.
“The R35 is defined by a powerful, continuous and fluid topside ribbon running from bow to stern. This is complemented by distinctive and purposeful side air blades. It’s a subtle new design language for us that perfectly complements the dramatic new performance.”
Andy Lawrence, Head of Design at Princess Yachts.
Interior / Onboard – A Life of Luxury
The R35 adds new meaning to Princess’ expression ’Experience the Exceptional’. And with the exceptional performance delivered via the new AFS and carbon innovation, the cabin reflects Princess’s expectation that owners and occupants will have an increased desire to stay aboard and therefore delivers the most luxurious of surroundings.
Step down from the cockpit via a sliding hatch to a stylish cabin, designed to give the best owner experience possible and filled with natural light. Elegant windows and a skylight also enhance the
feeling of space. A wet-room and lavatory allow comfortable days at sea, while the U-shaped seating surrounding a dining table easily converts into a double bed where integrated blinds ensure a good night’s sleep. The R35 features a convenient hot and cold shower facility on the aft swim platform too: the perfect place to refresh after a day in the sea.
Slightly aft, the practical galley kitchen features a sink, drawers and storage space. Guests can relax in front of a 32-inch LED television*, complete with Blu-ray CD/DVD player* that integrates with the Naim audio system. An ingenious forward-facing camera* on the bow delivers live footage to the forward screen, allowing guests to see where they are travelling from every angle.
The Princess Design Studio offers three beautifully resolved interior schemes that complement the 5 metallic paint finishes. The finest materials and textures combine to create a bespoke and luxurious space in the R35. This maintains the integrity of Princess in terms of practicality, wellconsidered execution and absolute attention to detail as the company layers on new levels of
technology and engineering design.
“It’s exciting to work on a project where some elements are more automotive driven in terms of using colour and trim as the main consideration. We have been able to draw on our expertise in yachting design to ensure that every finish is not only beautiful but also incredibly durable in a marine environment.”
Sarah Verey, Director of Creative Design at Princess Yachts.
Ownership
But owning an R35 isn’t just about having a yacht – it’s about being part of the Princess family. Princess Lifeline provides owners with 24/7 international access to medical and security assistance, or technical help from our global network of dealers. Whatever happens, owners are covered wherever they cruise for the first two years of ownership after which they can easily renew.
A familiarization course prior to delivery means owners can confidently take to the waves in the new R35 and experience the full benefit of Princess’s, and their key partners’, vision and dramatic
execution.
“Aside from the revolutionary technology, the look and design of the R35 is enough of a reason alone to make you fall in love with this yacht. One day all boats will be made like this and it is our ambition to introduce this new level of technology and desirability to all of Princess’s boats. Forget what you know about yachts – the R35 challenges and changes perceptions.”
Antony Sheriff, Executive Chairman, Princess Yachts.
