Ropes with Dyneema® RSK78 core and Technora® mixed sheath – Dyneema® and Polyester

Description

Versatile Ropes with Dyneema® SK78 Racing core and mixed Technora® – Dyneema® and Polyester sheathing

To meet the demands of intensive, continuous use in ocean racing, Lancelin has developed a high-performance Rope with a Dyneema core. The strength and durability of the modern fibers used enable us to maintain a relatively small diameter for maneuvers that are subject to high stresses and prolonged racing.

Advantages:

• Excellent abrasion resistance
• Good grip on winches
• High-performance Ropes with Dyneema core, low stretch

Use:

A technical Rope ideal for regattas and offshore racing, recommended for mainsail halyards and sheets, genoa sheets, spinnaker sheets and gennaker sheets.

Technical specifications:

• Sheathing: mixed 24-spindle sheathing in Technora®, Dyneema® SK78 and continuous polyester
• Core: 12-strand braid in Dyneema® SK78 Racing, sizing and hot pre-stretched
  

The benefits of pre-stretching the soul:

During braiding, air slips between the spindles, creating gaps. Pre-stretching a braid involves stretching the rope to orient the fibers in their working axis. By squeezing together, the spindles expel the air trapped in the braid. The result is a denser braid that will not stretch when first tensioned.

How to choose the right diameter :

First of all, think about the diameter accepted by your rope clamps. Without overglue, the minimum diameter recommended for a conventional rope clamp is likely to slip once under tension. To choose a smaller diameter, we advise you to use a Technora polyester overglaze at the blocker passage. It improves grip to prevent slippage and increases the longevity of your Rope by protecting it from abrasion by the blocker.

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

Here are a few guidelines:

To define the approximate breaking strength of your halyard (in kg) :

• Genoa area x 80
• GV surface x 100
• Spinnaker surface x 30

For the approximate length of your halyard :

• Genoa = Mast height x 3
• Spinnaker = Mast height x 3
• GV = Mast height x 2.5
