To achieve rigging with minimal stretch, high modulus and low weight, Alinghi worked with DSM Dyneema, the manufacturer of ultra-strong Dyneema polyethylene fiber, and Gottifredi Maffioli, a leading Italian rope maker. Together, they developed a unique rigging concept that features a core of Dyneema fiber with high strength at lower weight.
When Alinghi, the Swiss team that will defend its America’s Cup title this June, sought a fresh advantage through optimized running rigging, they looked for a winning technology solution. The previous rigging used by Alinghi needed frequent replacement and was heavier than desired.
The new solution provides a number of benefits, including lower stretch and significant weight savings. The lighter-weight and stiffer lines are expected to contribute to the team’s overall performance.
“To defend the America’s Cup, we’ll need the best possible technology,” said Grant Simmer, Design Team Coordinator of Alinghi.
“To improve the performance of our running rigging we decided to partner with the top experts. DSM Dyneema is the manufacturer of Dyneema, which is their ultra-strong lightweight High Performance PolyEthylene fiber – clearly the material of choice for a racing yacht’s rigging."
"And Gottifredi Maffioli is well-known for innovation in rope manufacturing. We are confident that their combined expertise and technology will contribute to a successful race.”
Running rigging made with Dyneema, the world’s strongest fiber enhances the performance of a yacht in several ways. First, it reduces weight above the waterline while maintaining high strength to boost performance. This high strength-to-weight ratio enables thinner-diameter ropes for easy handling and splicing, free running and smooth flaking.
The lower stretch provided by Dyneema fiber results in less energy absorption by the rigging, allowing the force of the wind to be largely converted into hull speed. Finally, this material is highly resistant to abrasion, chafing, bending fatigue and environmental factors, extending the useful service life of the rigging.
Rolf van Beeck, marketing manager Sports at DSM Dyneema said, “Technological breakthroughs first used in racing are often incorporated into consumer products at a later stage – for example, the transfer of technology from F1 auto racing to the modern car."
"We are proud to contribute to the overall competitiveness of Team Alinghi by improving its running rigging – which, together with the sails, is the ‘engine’ of the boat. This project gave us valuable insight into the future of sailing and opens up new opportunities to develop new products that answer tomorrow’s needs.”
