To meet the requirements on intensive and continuous use during offshore racing, Corderie Lancelin has developed a high-performance Héolia rope. The resistance and longevity of the modern fibres used enables the diameter to remain relatively small for control lines subjected to high tensile forces, during long racing periods.
Core pre-stretching advantages:
During braiding, air enters between the plaits and creates spacing. Pre-stretching of a braid consists in stretching the rope in order to direct fibres toward their working axle. By tightening together, the plaits expel air stuck in the braid. In this way, you can obtain a denser braid that will not undergo elongation as soon as it is put under load.
How to choose the right diameter:
First, consider diameter suitable with your clutches and cleats. Without adding a chafe sleeve, the minimum diameter that is recommended for a standard clutch may slip once the rope is under load. If you choose a lower diameter, we suggest adding a Technora Polyester type chafe sleeve at the passage point where your rope passes through clutches. It increases the grip, avoids slipping effect, increases the lifespan of your rope by protecting it from chafing caused by the clutch.Some points to guide you:
To estimate the breaking load of your halyard (in kg):– Genoa surface x 80
– Main sail surface x 100
– Spinnaker surface x 30
To estimate the length of your halyard:
– Genoa = Mast length x 3
– Spinnaker = Mast length x 3
– Main = Mast length x 2,5
