Replacing the anti-torsion cable on a gennaker or Code Zero is a crucial maintenance step to ensure smooth and effortless furling while sailing. An aging or soft line can twist unevenly, causing the sail to jam on the furler.

At the Clipper Voiles workshop in Frontignan, we systematically opt for "rigid" anti-torsion rope. Considerably more efficient and durable than softer alternatives often found on standard setups, it transfers rotational force instantly along the entire luff.

Here is the complete process to install your anti-torsion line correctly:

• 1. Gennaker preparation: Lay the sail out flat on a clean surface to keep the luff perfectly straight without introducing unwanted twists.

• 2. Tensioning for measurement: Apply tension to the luff to take precise measurements. Getting the exact length is essential to maintain proper sail shape once hoisted.

• 3. Cutting to exact length: Cleanly cut the rigid anti-torsion line according to your initial measurements.

• 4. Thimble fitting: Insert the heavy-duty thimble at the end of the cable, ensuring a solid connection to your furler drum or swivel.

• 5. Installing the heat-shrink protective sleeve: Apply a protective thermal sleeve over the termination to shield the fibers against friction, UV rays, and saltwater wear.

• 6. Final lashings: Complete the assembly with a secure lashing and whipping finish to lock everything permanently in place.
