Sailing yacht builder Beneteau has entered into a co-operation with Netherlands-based DSM Dyneema. The agreement aims to improve the sailing performance of Beneteau yachts through the use of next-generation running rigging made with Dyneema ultra-strong, lightweight polyethylene fibre. The high performance rigging, produced by Corderie Henri Lancelin, will be used in the majority of performance cruising sailboats built by Beneteau.

Compared with standard ropes made from polyester, rigging made with Dyneema is said to provide increased strength at lower weight. This enables ropes to have a smaller diameter for easier handling. Furthermore, by minimising weight above the waterline, sailing performance can be enhanced. This new rigging reduces stretch by a factor of three compared with polyester ropes, resulting in greater control and less energy absorption. Wind energy can also be largely converted into hull speed instead of being absorbed by the rigging.

Another benefit of the Dyneema fibre is said to be its durability. The high-modulus polyethylene fibre is highly resistant to abrasion, chafing, bending fatigue, UV light and salt water, producing a reliable rig with long service life. The smooth material also allows free running of the ropes.

To celebrate the co-operation, a Beneteau First 34.7 yacht rigged with ropes with Dyneema and skippered by Jimmy Pahun will compete in the Spi Ouest race in La Trinité-Sur-Mer, France.
