Cover Title Page Contents Introduction 1. Synthetic fibres

Developments Technical features

Breaking load Safe working load Stretch Creep

Synthetic fibres used for ropes Polyester Polyamide Polypropylene UHMWPE (Dyneema, Spectra) LCP (Vectran) PBO (Zylon) Aramid (Kevlar, Technora)

2. Construction of ropes

Twisted ropes Single braid ropes Double braid ropes Braided cover with a core of twisted strands or parallel fibres Additional types of rope construction

3. Which type of rope?

Sheets and halyards

Materials

Control lines and running backstays

Diameter and breaking load Length

Mooring lines

Diameter Length

Ropes combined with clutches Maintenance and troubleshooting

Inspection Friction and wear Rope does not hold in clutches Twisted ropes Cleaning ropes

4. Before you start

Splicing tools Splicing technique and core materials The size of the eye How to remove a core from the cover ‘Tapering’ the ends of a rope ‘Milking’ the cover Long bury splicing

5. Eye splice in plaited or twisted ropes

Three-strand rope Eight-strand rope

6. Eye splice in polyester ropes

Double braid rope

Stainless steel thimble

Rope with a laid core Rope with parallel fibres in the core

7. Eye splice in Dyneema ropes

Single braid rope

Basic method Method for hollow braid with a grip fibre Lock splice

Double braid rope

Without using the cover Using the cover Double layer cover

8. Dyneema shackles

Soft shackles

Type 1 Type 2 Integral

Soft shackle knot

9. Weight savings and tapering

Tapering a doubled braid Dyneema rope Joining two single braid ropes Joining steel wire with double braid polyester Joining a single braid Dyneema rope with double braid polyester

10. Thickening and strengthening

Splicing or sewing in an extra cover

Splicing in an extra cover Sewing in an extra cover

Splicing in an extra core

11. Continuous loops

Double braid polyester

For equal thickness, spliced without the core For strength, spliced with the core

Single braid Dyneema ('loop')

Basic loop Loop with cover

Double braid Dyneema

12. Whippings

Double stitched whipping for braided ropes Common whipping Whipping for a three-strand laid rope

13. Reeving of new halyards

Reeving eye (‘Flemish eye’) Reeving loop with whipping

14. Splicing tools

Using a soft needle How to make a soft needle
