Hydrogen-fuelled zero-emission chase boat demonstrates impressive range The hydrogen fuel cell powered chase boat, designed and built by Emirates Team New Zealand, was launched recently in Auckland. As a long-term official supplier to the America’s Cup team, Gurit played a significant role in this project, providing a complete package of advanced composite materials and structural engineering support.

ticking off her foiling and testing milestones. Latest reports from the team, based on sea trials, estimate a range of 165 nautical miles at around 30 knots on a full tank of hydrogen – this translates to just under 6 hours on the water - and the only by-product is water.

Chase Zero features Gurit Corecell™ M structural foam core, which was developed specifically for marine applications, offering superior dynamic energy absorption, high shear elongation for impact resistance and is suitable for high temperature processing. Gurit’s high-performance epoxy prepregs, with excellent mechanical performance and a 35-year race yacht history, were used throughout the vessel.

Gurit undertook Finite Element Analysis to meet the structural, performance and systems requirements June 2022 Gurit Marine Newsletter 1 of 8

“As the design of the primary structures was well underway before final design of the systems, we had to incorporate some versatility,” explains Tony Stanton, Engineering Manager, Gurit Asia Pacific. “The deck and topside hatches needed to be large enough to access the systems hardware; and had to be structural to keep the vessel’s weight down (she has a displacement of just 4800kg). In addition, the aft compartment had to allow sufficient ventilation for the hydrogen tanks that it houses.”

Gurit’s Engineering Team ran finite element analysis to optimise the hatches, creating a lightweight yet stiff platform, with as much open space as possible. The result is a unique lattice design on the deck.

Gurit has been a supplier to Emirates Team New Zealand, providing materials and technical support for the America’s Cup yachts, for over 15 years. This collaboration continues with the hydrogen chase boats, the AC40s currently in build at McConaghys China, and the land speed craft Horonuku, which has just completed testing in New Zealand and now heads to Lake Gardiner in Australia to attempt the land speed record.

The Sailing Museum - inspiring a new generation of sailors Gurit donated Bcomp ampliTex flax fibre fabric to Composite Energy Technologies for the creation of a spinnaker on a J/24 exhibit at the new sailing museum in Newport, Rhode Island, USA. The Sailing Museum is an educational non-profit organisation that features the

National Sailing Hall of Fame and America’s Cup Hall of Fame exhibits. In the space once used as the Press Room for the America’s Cup the heritage of sailing is celebrated, the legends of the sport honoured and new sailors and innovators inspired. Gurit is proud to have been able to contribute to this exhibit.

NEO 570c – bringing the Italian touch to racer/cruisers The Mediterranean Grand Prix sailing circuit has served as the proving ground for new design concepts for decades.

Paolo Semeraro and the team at Neo Yachts in Bari, Italy believe the Neo 570c racer/cruiser is the latest gamechanger on the scene.

The idea for the 570c first came about when Semeraro realised the boat he wanted to sail wasn’t available on the market: a fast racing boat with the same speed and performance on the water as a TP52, but also with a level of comfort and layout suitable for family cruising.

He believed that there was a potential market among owners who were seeking both adrenaline and pleasure from their yacht.

Looking for design inspiration, Semeraro approached Shaun Carkeek, a designer with a passion for creating innovative boats and keen to push the boundaries in naval architecture. Carkeek had a proven record of success and was eager to create a boat with a difference.

The 570c project commenced in earnest in 2019. Working with longtime partner and Gurit distributor Resintex, the Neo team selected a full complement of Gurit products to achieve the weight savings needed, including carbon fibre for the hull, deck, and internal structure.

The build team worked with a female mould, utilising Gurit carbon SPRINT™ and prepreg for the hull, as well as Corecell™ M structural foam; the deck also featured Gurit

The Neo team of Patroklos Tottas – Deckplan Manager, Paolo Semeraro – Project Manager and Anotonio Latini – Composite Manager prepreg carbon. The Ampreg™ laminating series, PRIME™ infusion systems and Spabond™ adhesive products were key in the construction of the internal structure.

To achieve the seemingly impossible, a forward-thinking team was essential. Paolo Semeraro reports, “The build of the 570c required a team of special people; it was key to have a team who were not constrained by previous ideas and who approached the build with an open mind. Every day we created something new. In this respect, it was also important to have suppliers and products that we trusted.

I have been using Gurit products since my first Neo 400 in 2013. Gurit’s long experience in producing high quality, certified prepreg materials made them my first choice, and Resintex helped guide the decision process.”

Laura Fabi of Gurit Authorised Distributor, Resintex adds, “Paolo is a great entrepreneur with an innate passion for sailing, surrounded by a network of experts, we are proud to support his projects.”

The stunning result is the Neo 570c, which embodies the future of dual-purpose yachts combining racing performance with high end design, styling and engineering.

The first Neo 570c was launched in June 2022 and the carbon moulds are now ready to begin boat 2.

Celebrating 42 years of excellence and Australian innovation Since Riviera’s inception in 1980, a culture of excellence has flourished, with innovation at the heart of everything the company does. Now, with 42 years and the experience of building more than 5800 luxury motor yachts behind the team, this approach continues.

New models offer a choice of 24 individual motor yachts from 39-78ft in length across five distinct model collections. With the latest boatbuilding techniques embraced and highest performing materials used, Riviera delivers a world class motor yacht experience for its owners. And the drive for continuous refinement and innovation is seen throughout the Riviera team, where the attention to detail and the culture of excellence is evident.

Gurit core materials are used throughout the Riviera range

The new flagship model, the Riviera 78 Flybridge

Gurit has been supplying Riviera with core materials for its full range of boats for over 15 years. In the early days, it was in the form of core kits as Riviera drove for improved efficiency in its composite department.

Quickly seeing the advantages of time saving, reduced waste, and consistently accurate shapes, the Riviera team drew on Gurit’s expertise to help them develop this approach in-house. Riviera now uses state-ofthe-art digital kitting to precisely cut all fibreglass and structural foams used in the lamination process. Gurit continues to supply structural core materials which provide reassurance of strength, impact resistance and durability to every Riviera luxury motor yacht.

“We have a long-standing partnership with Gurit,” says Kyle Davison of Riviera. “Continuity of supply and reliability of product performance are key aspects in creating the calibre of motor yacht that has earned Riviera global acclaim. And our partnership with Gurit helps ensure we maintain our international reputation.”

Riviera is a name synonymous around the world not only with luxury motor yachts but a unique lifestyle. When you buy a Riviera, you join a unique community of people who enjoy each other’s company, share adventures, and become part of the global Riviera family. This is encapsulated in the annual Riviera Festival of Boating, which this year was held alongside the Sanctuary International Cove Boat Show and saw the premiere of the 78 Motor Yacht, the new Riviera flagship model, the 4600 Sport Yacht Platinum Edition and 465 SUV, alongside boating seminars, on-water workshops, and several signature social events.

Successful together for innovative results Award-winning Carbon4Stack, for easier, faster, flexible processing of prepregs The Carbon4Stack solution, developed by Voith in partnership with Gurit, marks a technological breakthrough in the composites world by enabling a high volume and consistent serial production of carbon fibre-reinforced plastic components.

It is suitable for prepreg compression moulding, as well as in- and out-of-autoclave processing, and is available in variable thicknesses to a maximum sheet size of 1600mm x 1800mm. The flexible production process means that varying quantities can be produced, making it suitable for prototyping through to series production.

In short, Carbon4Stack are customised stacks made of pre-impregnated 50mm-wide UD tapes, with resin systems formulated to specific customer requirements.

Each tape is automatically placed using VRA (variable rate application) technology, creating the desired layup including local reinforcements in any fibre angle. The final stacks are multi-ply laminates with variable thicknesses and local reinforcements, manufactured in near net shape to provide the ideal solution for each case and application.

Carbon4Stack offers significant time and cost savings for manufacturers by drastically reducing the number of manual processes and amount of waste generated during the production cycle.

The Voith Inline Thruster CFRP rotor blade This year, the Voith Inline Thruster CFRP rotor blade using Carbon4Stack and Carbon4Tool was awarded the JEC Composites Innovation Award in the “Maritime Transportation Shipbuilding” category, for enabling optimal vessel manoeuvrability in the marine industry. The carbon fibre rotor blades are lighter, stiffer and more resistent to corrosion than if they were made with conventional materials.

The innovative design is the result of a close R&D cooperation between Voith Composites, Voith Turbo, Gurit and Cotesa.
