All-rounder rope, SK78 Dyneema® core, Technora® – Dyneema® and Polyester cover

Description

All-rounder rope, SK78 Dyneema® core, Technora® – Dyneema® and Polyester mixed cover

To meet the requirements of intensive and continuous use during offshore racing, Corderie Lancelin has developed a high-performance Dyneema core 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.

Advantages:

• Very high resistance to abrasion
• Good grip on winches
• High-performance rope, Dyneema core, low elongation

Application:

A technical rope ideal for regattas and offshore racing recommended for mainsheet, genoa sheet, spinnaker sheet and gennaker sheet.

Technical specifications:

• Cover: mixed Technora®, SK78 Dyneema® and Polyester continuous 24-plait core
• Core: 12-plait SK78 Dyneema® coated and heat-stretched braid
  

Core pre-stretching advantages:

During braiding, air enters between the plaits and creates spacing. Pre-stretching a braid consists in stretching the rope in order to orient fibres toward their working direction. By tightening together, the plaits expel captive air from 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 though clutches. It increases the grip, avoids slipping effect, increases longevity of your rope by protecting it from chafing caused by the clutch.

Diamètre	Charge de rupture - Âme RSK78	Poids/mètre
6 mm	2 300 kg	31 g
8 mm	3 750 kg	44 g
10 mm	6 900 kg	68 g
12 mm	9 000 kg	96 g

Some points to guide you:

To estimate the approximate breaking load of your halyard (in kg):

• Genoa surface x 80
• Mainsail surface x 100
• Spinnaker surface x 30

For the approximate length of your halyard:

• Genoa = mast height x 3
• Spinnaker = mast height x 3
• Mainsail = mast height x 2.5
