Sailing lines are constructed from various types of fibers, including nylon known for its elasticity and shock absorbency; polypropylene which is lightweight and floats on water; and polyester which strikes a balance with good strength, low stretch, and UV resistance.


Nylon holds a place of prominence in the world of sailing, with good reason. This robust material shows off its strength by maintaining integrity under high loads. Its standout feature – the ability to stretch and absorb shock makes it ideal for lines where sudden stress may occur, offering a margin of safety to sailors.

It endures abrasion and UV radiation remarkably well increasing its lifespan on your sailboat. A bonus is nylon’s resistance against chemicals; not to mention, handling these ropes comes easily even under wet conditions!


Polypropylene ropes have a unique place in the boating world. This type of line, often recognized as “yellow rope,” is commonly utilized for towing duties due to its buoyant nature, allowing it to conveniently float on water surfaces.

Its bright color and floating feature make it a favorite among sailors who enjoy water sports such as skiing or wakeboarding.

Despite these advantages, polypropylene has distinct drawbacks related to UV resistance and longevity. Exposure to sunlight degrades the strength of these ropes over time, shortening their lifespan compared to other line materials.

Consequently, frequent replacement may be necessary if the rope starts showing signs of wear and tear due to UV rays or general aging.


Polyester sailing lines boast strength and durability, making them a reliable choice for many sailors. The initial stretch of polyester rope is significant but it continues to elongate over time, compromising its low-stretch line attribute.

Sailors should note that this heavy-duty rope tends to absorb water which might make handling challenging during high-load applications. Unfortunately, despite its robust nature, polyester has poor resistance against abrasion and has a relatively lower breaking strength in comparison with ropes of similar diameter.

Its susceptibility to UV rays also contributes to the faster aging and wear and tear of the sailing line.

Identifying the Right Sailing Lines for Different Uses

When choosing sailing lines, it’s crucial to consider their specific uses such as the main halyard and jib/genoa halyard for raising sails, the spinnaker halyard for flying a spinnaker, mainsheet, and jib/genoa sheet for adjusting sail trim, spinnaker sheets for handling the spinnaker during downwind courses, and control lines like vangs and travelers that adjust tension on various parts of your rigging.

Main Halyard and Jib/Genoa Halyard

The main halyard and jib/genoa halyard are crucial components of your sailboat rigging. These ropes must withstand heavy loads and have low stretch to properly control the sails. You can choose among several types of rope for these lines, each with its unique properties.

Polyester rope is widely used due to its strength and durability. However, it’s heavier and absorbs more water over time compared to other materials like Aramid or Liquid Crystal Polymer (Vectran®) ropes that offer excellent heat resistance, high break strength, and minimal elongation under load.

Consider the specific needs of your sailing rig before purchasing a rope for this purpose.

Spinnaker Halyard

Spinnaker halyards demand ropes with high break strength and low stretch to handle the sail’s weight and wind pressure. Many sailors opt for a Polyester rope; its durability, low-stretch properties, and strength make it a go-to choice for this purpose.

It can withstand harsh weather conditions while maintaining its integrity.

Some spinnaker halyard lines employ aramid ropes like Technora®, Twaron®, or Kevlar® as they resist heat well and exhibit commendable durability under tension. Liquid Crystal Polymer (Vectran®) is another favored material since it doesn’t absorb water, making your line lighter and easier to manage on deck.

HMPE (Spectra®, Dyneema®), despite having a higher price point, justifies its use with excellent heat resistance, superior elongation control, and unmatched break strength.


The mainsheet is the line you’ll rely on to make significant adjustments to your sail’s angle relative to the wind. This crucial rope connects your boom to the deck, allowing sailors direct control over their boat’s speed and sailing direction.

Mainsheets must exhibit a high level of tensile strength and have minimal stretch, as they continually experience a lot of load during any sailing journey. Sailors often prefer ropes made from durable materials like Polyester or HMPE (such as Spectra® or Dyneema®) for their mainsheets due to these materials’ excellent balance between strength and resistance against wear and tear.

By opting for top-quality mainsheet material, you guarantee an efficient sailing experience while ensuring that safety remains paramount at all times.

Jib/Genoa Sheet

Understanding the functionality of a Jib/Genoa Sheet plays a vital role in effective sailing. These sheets are utilized to control the jib or genoa sail’s angle relative to wind direction on a sailboat.

The selection of these lines is crucial as they must have low-stretch characteristics, ensuring efficient energy transfer from the sails down through the hull into forward motion. Sheets like Spectra® or Vectran®-based rope fulfill this purpose and offer advantages such as reduced elongation under load and superior abrasion resistance for longevity.

For high-load applications on larger cruising vessels, blended double braid Beltran® or Spectra® rope serves ideally while club racing demands Vectran® or Spectra®, facilitating higher load handling capacity.

Spinnaker Sheet

Spinnaker sheets demand a low-stretch line due to their high-load applications. This specific sailboat rigging type is essential for maneuvering the spinnaker, a large triangular sail at the front of the boat.

Quantum Sails and New England Ropes are popular choices amongst sailors for their superior break strength and UV resistance properties. Always opt for a robust material like Spectra® or Dyneema® as they’re designed to withstand significant abrasion resistance, making them ideal for use with deck fitting on your sailing vessel.

It’s also worthwhile noting that color coding your spinnaker sheet makes it easier to manage amidst other control lines during hectic sailing conditions.

Control Lines

Dyneema® and Vectran® ropes are among the top choices for control lines. Even though Dyneema® tends to creep slowly over time, it’s an excellent choice due to its high strength.

Vectran®, on the other hand, is extremely low-stretch and lightweight, making it ideal for this role as well.

Selecting an Aramid or Polyester type rope can also serve you well. With Polyester known for its strength, durability, and low stretch capacity, it’s aptly suited for withstanding frequent adjustments under load – typical of most control line applications.

Moreover, aramid ropes offer great heat resistance along with substantial strength properties that make them viable contenders in crafting reliable control lines.
