Expert advice on choosing, installing, and maintaining your Seldén roller furling system.
Not all sailing blocks are created equal. The bearing type determines how smoothly a block turns, how much load it can handle, and how long it lasts. In this article we explain the three bearing types and help you choose.

Read articleExpert answers to common questions about Seldén furling systems
A roller furling system allows you to roll your headsail around a foil attached to your forestay, making sail handling safer and easier. The Seldén Furlex system uses a patented drum mechanism with ball bearings for smooth operation. You simply pull a furling line to wrap the sail, and release the sheets to unfurl. This eliminates the need for sail changes and makes singlehanded sailing much more manageable.
The choice depends on your boat size, sailing style, and budget. Manual furling systems like the Seldén Furlex are reliable, lightweight, and cost-effective for boats up to 14 metres. Electric systems like the Furlex Electric or CXe are ideal for larger boats, shorthanded crews, or sailors who want push-button convenience. Electric systems add weight but reduce physical effort, especially valuable for Code Zero and gennaker sails that require frequent furling adjustments.
Furlex sizing depends on your forestay length, wire diameter, and sail area. Seldén offers Furlex models from size 50S (for boats 6-8 m) up to size 400S (for boats 14-17 m). Use the forestay length as your primary guide: measure from the stemhead fitting to the masthead. For accurate sizing, consult the Seldén sizing chart or use our product advisor tool which considers your specific boat specifications.
Through-deck installation routes the drum below deck for a cleaner foredeck appearance. Installation requires: 1) Removing your existing forestay, 2) Cutting a hole in the deck for the drum housing, 3) Installing the deck seal and drum unit, 4) Assembling the foil sections around your forestay wire, 5) Fitting the top swivel and halyard connection. Seldén provides detailed installation manuals, and the process typically takes 4-6 hours for experienced DIYers. Professional installation is recommended for optimal results.
Seldén Furlex stands out through: 1) Patented "free-turn" function that prevents halyard wrap, 2) Unique load distribution system that extends bearing life, 3) Pre-assembled components for easier installation, 4) Anodized aluminum construction with stainless steel bearings, 5) Swedish manufacturing with automotive-level quality control. With over 200,000 units sold since 1983, Furlex is the world's best-selling roller furling system and is the OEM choice for Hallberg-Rassy, Swan, and Oyster yachts.
