A good furling line makes sail handling easier, safer and more reliable. Whether you use a furling headsail, Code 0, gennaker or in-boom mainsail system, the right line must run smoothly, give enough grip and handle the loads from the sail.
Quick answer. Choose a furling line based on your furling system. Use Cruising Furl for most roller furling headsails, Endless Racing for Code 0 and gennaker furlers, Dinghy Furl for small boats and Continuous Pro for in-boom mainsail furling systems.

What is a furling line?
A furling line is a rope designed specifically for furling systems. It allows you to roll sails in or out safely and with minimal effort, usually from the cockpit.
Furling lines are used on several systems, including roller furling headsails, genoas, Code 0s, gennakers and in-boom mainsails.
Rigging tip.
A good furling line should not only be strong. It must also have grip, flexibility and the right diameter for the furling drum or continuous furler.
Where are furling lines used?
Different furling systems need different rope properties. A headsail furling line does not always need the same construction as an endless Code 0 furling line or an in-boom mainsail furling line.

Key features of a good furling line
A furling line works under load and often runs through blocks, fairleads and a furling drum. That means it needs the right balance between strength, grip and flexibility.
- Strength and durability - the line must withstand sail loads and regular wear.
- Grip - grip fibres help with controlled handling, even under tension or in wet conditions.
- Flexibility - the line must run smoothly through blocks, drums and furling systems.
- Spliceability - endless furling systems need a line that can be spliced into a continuous loop.
- Correct diameter - the line must fit the furling drum and should not overload the system.
Which furling line should I choose?
We offer different furling lines for different furling systems. Choosing the right product depends mainly on your sail type and furler type.

Cruising Furl
Cruising Furl is ideal for cruising sailors who want a reliable and easy-to-handle furling line. The extra grip fibres make the line versatile and suitable for both roller furling headsails and in-boom mainsail systems.
It is a good choice for common furling systems such as Harken and Furlex, where dependable grip and smooth handling are important.
- Ideal for cruising yachts
- Good grip for easy furling and reefing
- Suitable for headsails and in-boom mainsails
- Compatible with common systems such as Harken and Furlex

Endless Racing
Endless Racing is designed for high-performance applications such as gennaker and Code 0 furling systems. These systems often use a continuous loop, so the line must be strong, flexible, grippy and suitable for an endless splice.
This line is available in diameters from ø5 mm to ø10 mm and can optionally be supplied pre-spliced.
- Designed for Code 0 and gennaker furlers
- Excellent grip for continuous furling systems
- Strong and flexible under load
- Available in ø5 mm to ø10 mm
- Can be supplied as a pre-spliced endless loop

Endless furling systems.
For Code 0 and gennaker furlers, the quality of the endless splice is very important. A smooth splice helps the line run cleanly through the furler and blocks.
Dinghy Furl
Dinghy Furl is specifically developed for dinghies and small boats. It is suitable for smaller furler drums and lightweight furling applications.
This line is available in ø5 mm and ø6 mm, making it ideal for small headsail furling systems where a standard yacht furling line would be too large or heavy.
- Designed for dinghies and small boats
- Suitable for smaller furler drums
- Available in ø5 mm and ø6 mm
- Lightweight and easy to handle

Continuous Pro
Continuous Pro is developed for in-boom furling systems where the mainsail is rolled into the boom. These systems require a line that is flexible, wear-resistant and stable in diameter over time.
For mainsails that roll into the boom, such as on catamarans and X-Yachts, a strong and flexible furling line is crucial. Continuous Pro is designed for these heavy-duty applications.
- Developed for in-boom furling systems
- Wear-resistant construction
- Flexible under load
- Maintains its diameter over time
- Performs well in heavy-load mainsail furling systems

Can I taper a furling line?
Yes, in some cases tapering is possible. A tapered furling line can help prevent the rolled-up part of the line from becoming too thick inside the furling drum.
This can be useful when the furling drum has limited space or when a full-diameter line creates too much build-up. You can order tapered furling lines from us. Simply provide the desired length and diameter and we can prepare a quote.
When tapering helps.
Tapering is mainly useful when the line takes up too much space in the furling drum. It should always be done carefully so the line still has enough strength where it is loaded.
How do I replace an endless furling line?
Replacing an endless furling line is straightforward when you know the correct diameter and length. Measure the old line carefully before ordering a new one.
- Measure the diameter of the existing line
- Measure the total loop length
- Check how the line runs through the furler and blocks
- Order the correct line and splice option
- Feed the prepared endless loop back into the drum and system
We can prepare the line so it is ready to be fed into the drum.
Which furling line do I need for my furlerboom system?
For furlerboom systems and in-boom mainsails, a strong and flexible line is essential. The line must keep its diameter, resist wear and run smoothly under load.
Continuous Pro is a strong choice for these systems. It is wear-resistant, maintains its diameter and performs well under heavy loads.
Why choose a good furling line?
A good furling line makes the difference between smooth sail handling and struggling with your sails. The right line gives more control, improves safety and reduces wear on both the rope and the furling system.
- Less effort - easier sail handling, even in stronger wind.
- More safety - you can operate the system from the cockpit and avoid unnecessary trips to the foredeck.
- More control - better grip helps you furl and reef more accurately.
- Longer lifetime - less wear on both the line and the furling system.
Rigging advice.
“A furling line should run smoothly, grip well and match the system exactly. The right line makes furling easier, safer and much more reliable.”

Frequently asked questions about furling lines
What type of furling line do I need?
Most boats have a roller reefing system with a forestay profile. Common systems include Harken, Furlex, Profurl and Facnor. These systems usually use polyester furling lines with good grip. We offer specially developed furling lines that are strong, reliable and equipped with grip fibres for easy handling.
Can I taper a furling line?
Yes, in some cases tapering is possible. Tapering helps prevent the rolled-up part of the line from becoming too thick in the furling drum. This can be useful when drum space is limited.
How do I replace my endless furling line?
Measure the diameter and total loop length of the existing line. Then order the correct line and splice option. We can prepare the endless furling line so it is ready to be fed into the drum and blocks.
Which furling line do I need for a furlerboom system?
For furlerboom systems and in-boom mainsails, choose a strong, flexible and wear-resistant line that keeps its diameter under load. Continuous Pro is developed for this type of application.
What is the difference between Cruising Furl and Endless Racing?
Cruising Furl is ideal for cruising yachts with roller furling headsails or in-boom systems. Endless Racing is designed for high-performance continuous furling systems such as Code 0 and gennaker furlers.
What diameter furling line do I need?
The correct diameter depends on your furling system, drum size and load. Smaller systems may use ø5 mm or ø6 mm, while larger yacht systems often need a larger diameter for grip and strength. Always check the furler specifications or ask our rigging team for advice.
Can I order an endless furling line pre-spliced?
Yes. Endless furling lines can be supplied pre-spliced. This is especially useful for Code 0, gennaker and continuous furling systems where a smooth endless loop is required.
Why does grip matter in a furling line?
Grip is important because furling lines are often handled under tension and in wet conditions. Extra grip fibres help you control the sail more easily and reduce slipping in the hand or system.
Can I get advice on choosing the right furling line?
Yes. Our rigging team can help you choose the correct furling line based on your boat, sail type and furling system. Chat with our riggers on WhatsApp or contact us directly.
