In a historic victory, INEOS Britannia has clinched the Louis Vuitton Cup, securing their place in the 37th America’s Cup Match against Emirates Team New Zealand. This marks the first time in 60 years that a British team has made it to the finals, after Ben Ainslie’s crew triumphed over Luna Rossa Prada Pirelli with a 7-4 victory. The advanced manufacturing techniques and materials used in this race, particularly carbon fibre, were key to their success. Gandtrack’s tooling for composites played an essential role in manufacturing quality components for the AC75 race yacht.
The demands placed on modern race yachts extend far beyond traditional boatbuilding. Every component must combine low weight, high strength and exceptional accuracy, often while operating under extreme loads. This makes material choice, manufacturing quality and specialist tooling for composites particularly important. Composite materials have become central to this development, allowing engineers to create lightweight structures without compromising the rigidity and strength required at the highest level of competitive sailing.
THE ROAD TO VICTORY
The America’s Cup, the world’s oldest international sporting event, has been a challenging race for Britain to conquer. Since its inception in 1851, no British team has won it, but INEOS Britannia is now one step closer to breaking that streak. Ainslie’s team has set the stage for what could be a historic triumph, and their journey wouldn’t have been possible without the precision manufacturing and materials used in their AC75 boat. From the hull to the sails, Gandtrack’s tooling for composites ensured the precision needed for both strength and aerodynamics.
Behind every high-performance yacht is an extensive manufacturing process involving designers, engineers, machinists and composite specialists. Small improvements in weight, accuracy or component finish can contribute to overall performance. For manufacturers working with advanced composites, maintaining consistency throughout production is essential, particularly when components are manufactured to demanding tolerances and must perform reliably under race conditions.
This is where specialist tooling for composites becomes increasingly important. Carbon fibre and other composite materials can present challenges such as delamination, fibre breakout, fraying and rapid tool wear. Choosing the correct geometry for the material and application can help maintain component quality while reducing the risk of damage during machining.
THE PINNACLE OF SAILING TECHNOLOGY
The AC75 class represents a monumental leap in sailing technology, akin to comparing Formula 1 cars to standard vehicles. These foiling monohull yachts are designed to lift out of the water, allowing them to sail up to four times faster than the wind. The second generation of AC75s, set to compete in the upcoming America’s Cup, features even wider foils and a host of refinements that promise to enhance performance.
The performance of these boats relies on the close integration of aerodynamic design, hydrodynamics, materials science and precision manufacturing. Weight must be carefully controlled while components still need to withstand enormous forces. Carbon fibre provides an excellent combination of strength and low weight, but producing accurate features within composite structures requires specialist machining knowledge and the correct tooling for composites.
Even relatively simple operations such as drilling a hole can become critical when working on advanced composite components. Poor tooling can damage fibres, reduce hole quality or require additional finishing operations. In a high-performance environment, this can increase manufacturing time and potentially compromise the component itself.
WHY THE GT-50 DAGGER DRILL?
The GT-50 Dagger drill, along with the full range of Gandtrack’s carbide tooling for composites, is specifically designed to meet the demands of working with high-performance materials like carbon fibre. Precision engineering lies at the core of our carbide drills, allowing them to handle the intricacies of advanced composites with ease. These tools ensure clean, quality, high tolerance holes that are essential for maintaining the integrity of crucial components like hulls, sails, and foils.
In addition to precision, enhanced performance is a hallmark of the GT-50. Its unique geometry reduces friction and optimizes chip removal, enabling manufacturers to work efficiently without sacrificing quality. This is especially important in fast turnaround environments where speed and accuracy are critical.
Moreover, versatility is a key advantage of Gandtrack’s carbide tooling. Our range of drills provides manufacturers with the right tool for every specific task, ensuring flawless execution whether you’re cutting through carbon fibre for a yacht’s hull or drilling intricate components for its sails and foils. The GT-50 stands out in its ability to consistently deliver reliable results across a variety of complex applications.
For manufacturers, selecting the right drill can also help improve process consistency. A tool that produces a clean, accurate hole from the outset can reduce the need for secondary finishing operations and minimise the possibility of scrapping an expensive composite component. This becomes particularly valuable when working with complex parts that may already have undergone many hours of manufacturing before drilling takes place.
Other options for drilling carbon fibre include:
The GT-15 will drill and ream in a single operation for high tolerance holes from 2.3mm.
The GT-105 will create a burnishing effect with its 4 lands for stability. Available from 2.5mm.
The GT-250 reduces delamination in ferrous materials like Kevlar, and has been proven to work extremely well with carbon fibre applications. Available from 2.4mm.
The GT-240 will drill quality holes in one shot in automated controlled feed machines due to its trepanning action. Available from 4mm.
Together, these options allow manufacturers to select tooling according to the specific requirements of the component, material, machine and finished hole. Different applications may prioritise tolerance, stability, reduced delamination or the ability to combine multiple operations, making tool selection an important part of the overall manufacturing strategy.
