Furlex 20S: Precision Furling for Small Boats

For sailors of small keelboats and performance dinghies, headsail handling can be a challenge—especially when sailing solo or in gusty conditions. The Furlex 20S from Seldén is purpose-built to solve that problem. It’s the smallest member of the Furlex family, designed for boats up to 2,000 kg displacement, offering smooth furling, lightweight construction, and the same engineering pedigree found in Seldén’s larger systems.

Whether you're racing around the cans or cruising a lake, the Furlex 20S delivers reliable furling in a compact, easy-to-install package.

⚙️ Key Features of the Furlex 20S

1. Lightweight Design

Weighing just a few kilograms, the Furlex 20S is ideal for boats where weight aloft matters. It’s built from marine-grade aluminium and stainless steel, ensuring strength without compromising performance.

2. Single Extrusion Foil

Unlike larger models with twin grooves, the 20S uses a single-groove foil, optimized for simplicity and weight savings. It’s perfect for boats that carry one headsail at a time.

3. Compact Drum with Line Guide

The furling drum is designed to coil the furling line evenly, reducing friction and preventing jams. The line guide keeps the line organized and easy to handle, even in breezy conditions.

4. Complete Kit

The Furlex 20S is delivered as a ready-to-install kit, including:

• Forestay wire
• Halyard lead
• Furling line
• Stanchion blocks
• Sail feeder

No need for swaging—mechanical terminals like Sta-Lok are compatible, making installation accessible for DIY sailors.
