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.
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. 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.
