Furlex 404S: Ultimate Furling Power for Bluewater Yachts

When your yacht is built for ocean crossings, high latitudes, or serious offshore racing, your gear needs to be uncompromising. The Furlex 404S is Seldén’s top-tier manual furling system, designed for yachts up to 65 feet and 20 tonnes displacement. It’s the largest model in the Furlex S-series, engineered to deliver smooth furling, precise sail control, and rugged durability in the harshest conditions.

🛠️ Key Features of the Furlex 404S

1. Heavy-Duty Bearings

The 404S uses multiple sets of stainless steel ball bearings and roller bearings within the drum and swivel. This ensures low friction and high load capacity, even under extreme tension.

2. Twin-Groove Luff Extrusion

Like its smaller siblings, the 404S features a twin-groove foil, allowing for fast sail changes or twin headsail setups—ideal for downwind passages with poled-out genoas.

3. Integrated Rigging Screw (Optional)

An integrated rigging screw allows precise forestay adjustment without altering tack height. This is essential for tuning mast rake and optimizing sail shape on large yachts.

4. Split Drum with Line Guide

The split drum design ensures even furling line distribution, reducing jams and friction. The line guide keeps the furling line neatly coiled and easy to handle.

5. Corrosion Resistance

The system includes insulated joining sleeves and composite connectors to minimize galvanic corrosion—critical for long-term reliability in saltwater environments.
