What is heat-setting a rope?

Heat-setting is a pre-stretching process carried out at a temperature of 100°C to improve fiber compaction and stabilization. This process improves a rope's mechanical properties and lifespan. It is reserved for high-end ropes intended for demanding applications.

Many natural fibres are used to make rope:

hemp
cotton
sisal
jute
linen
coconut fibre

The strongest material is hemp. The most used materials in decoration are cotton and jute.

Polypropylene
Textured polypropylene (synthetic hemp)
Polyester
Nylon (Polyamide)
Polyethylene
Steel
Latex

The breaking strength of a rope varies according to its raw material, construction, density, and diameter.

Download our comparison of the breaking resistance of all our natural and synthetic ropes from 2mm to 40mm!

The tensile strength is the tensile capacity of a new rope when it is new, static, straight, knot-free and splicing-free. A tolerance of +/- 7% is always applied for the breaking resistance of a rope. For safety, no more than 80% of the breaking load of a rope when it is new should be used.

Expressed in KG, it refers to the tension capacity at standstill (weight); while expressed in decanewton (DaN), it refers to the tension capacity in motion (weight x speed). The use of a rope reduces its breaking resistance.

The main factors that attenuate a rope’s strength are: moisture, UV rays, heat, frost, abrasion, knots, splicing and chemical agents.

The majority of our ropes for decoration are made in France. The origin of our ropes is specified in the product descriptions.

Anti UV treatment

To stay intact in the face of prolonged exposure to the sun, our synthetics are treated to resist UV.

Better resistance to weather

Rain, snow, sea water... Our synthetic ropes are designed to last in the face of moisture and corrosion.

Longer life

The synthetic rope is suitable for long-term decoration of your exterior. You can choose the synthetic hemp rope for a natural effect guaranteed.

Polyester ropes have excellent abrasion resistance, very good knot holding and low elongation.

Polyester rope is water repellent and do not lose their strength when wet. It is non-floating. It is resistant to moisture.

Density: 1.38

Polyester has excellent UV resistance. It is ideal for long-term outdoor exposure.

Polyester fiber is resistant to mites, bacteria, mold, mineral and organic acids, oxidants and diluted alkalis.

It is sensitive to strong alkalis, some phenols, benzyl acetate and nitrobenzene.

The thermal properties of polyester ropes are as follows:

Critical temperature: ± 180°C
Melting temperature: ± 260°C
Smell of hot oil with flame, black smoke
Flame-retardant

A Garcette (lashing line) is a small synthetic rope with a diameter generally less than 5mm used to do all kinds of small work on a ship.

A halyard is used to hoist a sail to the top of the mast, while a sheet is used to adjust its angle relative to the wind.
It is the sheet that allows you to control the boom and trim the sail to gain or reduce speed.

Dyneema® is the benchmark technical fiber for halyards and sheets. Both very lightweight and extremely strong, it stands out for its near-zero stretch, ensuring precise and consistent trimming over time.
Long reserved for high-performance sailing, it is now widely used on demanding cruising boats. Its higher cost is justified by its performance and durability.

More accessible, polyester is the most commonly used material on cruising boats, valued for its versatility. It performs well under constant load and offers good resistance to UV and seawater. However, it does have some stretch, making it a good compromise between strength, durability, and flexibility.

Polyamide (nylon), a stiffer and more elastic material, is generally reserved for mooring and anchoring lines

Which materials ?

Polyamide (nylon) is the most suitable fiber for mooring lines. Highly elastic and resistant to abrasion, it effectively absorbs shocks caused by the boat’s movements. Its UV resistance is, however, slightly lower than that of polyester.
Polyester is a durable alternative, known for its excellent resistance to UV and abrasion. Its lower elongation makes it less effective at absorbing shocks, but more suitable for stable mooring lines.
Polyethylene, thanks to its floating properties, is useful for specific applications such as buoy pick-ups, temporary moorings or areas with propeller risk.

Three-strand or braided mooring line?

Three-strand: more rigid, it is mainly appreciated for its ease of splicing, ideal for making loops or custom mooring lines.
Braided: more flexible and comfortable to handle, it offers better comfort when maneuvers are frequent.

What length? What diameter?

Diameter: boat length (in meters) + 4. Example: 6 m boat → recommended diameter: 10 mm
Length: choose mooring lines measuring 2 to 3 times the length of the boat to maintain flexibility and effectively absorb loads.

Polyamide (nylon) and polyester fibers are the most commonly used in boating. Both offer good resistance to UV, salt and marine conditions.

Polyamide (nylon) is particularly recommended for mooring lines. Highly elastic, it effectively absorbs shocks, but may stretch and slightly lose strength when wet.
Polyester, more stable, is a versatile fiber used for mooring lines as well as halyards and sheets. It has excellent resistance to UV and abrasion, with lower elongation.
Polyethylene, lightweight and floating, is mainly intended for specific uses such as buoy pick-ups or temporary moorings.
Hemp, historically used on traditional rigs, is now appreciated for its authentic look, although it is less suited to intensive use in a marine environment.

Recommended diameter: 3, 4 or 5 mm, depending on the desired look. Please note that only our 3 mm x 50 m spool fits through the center of an Acapulco chair.
Recommended length: approximately 150 m of cord for one chair.
