Furlex 304S: Precision Furling for Serious Sailors

When it comes to headsail furling systems, few names carry the pedigree and trust of Seldén’s Furlex range. The Furlex 304S, part of the fourth-generation lineup, is engineered for yachts up to 15 tonnes displacement and represents a fusion of durability, innovation, and ease of use.

Whether you're cruising across the Channel or racing offshore, the 304S offers the kind of reliability that seasoned sailors demand.

⚙️ Key Features of the Furlex 304S

1. Patented Load Distributor

Seldén’s hallmark innovation—a patented load distributor—ensures low furling resistance and exceptional bearing durability. This design evenly spreads the load across the bearing surfaces, reducing wear and making furling smoother under load.

2. Twin-Groove Extrusion

The 304S features a twin-groove foil, allowing for rapid sail changes and the option to fly twin headsails—ideal for downwind sailing or racing configurations.

3. Integrated Rigging Screw

An optional integrated rigging screw allows precise forestay adjustment without altering the tack height. This is especially useful for tuning mast rake or adjusting sail shape without compromising furling performance.

4. Lightweight Halyard Swivel

The halyard swivel is designed to minimize weight aloft, improving sail balance and reducing pitching. It also rotates freely under load, preventing halyard wrap and ensuring consistent furling.

5. Corrosion Resistance

The system includes insulated joining sleeves and a composite connector, which reduce galvanic corrosion and improve longevity—especially important for yachts in saltwater environments.

📐 Technical Specifications

🧰 What’s in the Kit?

The Furlex 304S comes as a complete kit, including:

• New forestay wire
• Furling line
• Stanchion lead blocks
• Halyard lead
• Pre-feeder
• Optional Sta-Lok fittings for mechanical wire termination

Installation can be completed in a few hours with basic tools, and the system is designed to be user-friendly even for DIY riggers.

🧭 Performance and Handling

Sailors report that the 304S performs smoothly in light and heavy conditions alike. The split drum and line guide system ensure the furling line coils evenly, reducing jams and friction. The tack swivel allows the sail to furl tightly and evenly, preserving sail shape even when reefed.

However, like any furling system, proper setup is key. Issues such as halyard wrap or excessive forestay tension can impair performance. Regular inspection and correct halyard tensioning are essential for optimal operation.

🛠️ Ideal Applications

The Furlex 304S is best suited for:

• Bluewater cruisers seeking reliability and ease of reefing
• Performance cruisers who want fast sail changes and minimal stretch
• Racers using twin headsails or needing precise forestay tuning

🧾 Final Thoughts

The Furlex 304S is more than just a furling system—it’s a precision-engineered solution for serious sailors. With its robust construction, thoughtful design, and proven performance, it stands as one of the top choices for yachts in the 10–15 tonne range.

Whether you're upgrading your rig or outfitting a new build, the 304S delivers the kind of confidence that only comes from decades of Seldén innovation.
