Furlex 404TD: Through-Deck Furling for Bluewater Precision

For yachts over 50 feet, sail handling demands gear that’s not only powerful but also refined. The Furlex 404TD is Seldén’s top-tier through-deck furling system, engineered for boats up to 20 tonnes displacement. It combines the mechanical strength of the Furlex 404S with a sleek below-deck configuration—delivering longer luff lengths, improved sail efficiency, and a clean foredeck layout.

Whether you're crossing oceans or optimizing your rig for performance cruising, the 404TD offers the kind of engineering excellence that serious sailors rely on.

⚙️ Key Features of the Furlex 404TD

1. Below-Deck Drum Placement

The furling drum is mounted beneath the deck, allowing the sail to be tacked at deck level. This increases the effective luff length, improving sail shape and pointing ability—especially valuable for offshore and performance-oriented yachts.

2. Compact Drum Design

The MkII version features a smaller drum diameter than earlier TD models, simplifying installation in narrow anchor lockers and enabling placement further forward for optimal geometry.

3. Free-Turning Tack Swivel

The tack swivel rotates freely under load, reducing furling resistance and helping flatten the sail when reefed—essential for maintaining sail shape in heavy conditions.

4. Roller and Ball Bearings

The system uses roller bearings and stainless steel ball bearings in the drum and swivel, ensuring smooth furling under load and long-term durability.

5. Optional Rigging Screw

An integrated rigging screw is available, allowing forestay adjustment without altering tack height—ideal for tuning mast rake or sail tension.

📐 Technical Specifications

🧰 What’s Included in the Kit?

The Furlex 404TD is delivered as a complete installation kit, including:

• Forestay wire (cut to length)
• Through-deck drum unit
• Halyard swivel
• Sail feeder and pre-feeder
• Optional rigging screw or Sta-Lok terminal

Installation requires access to the anchor locker or bow compartment and is best performed by a professional rigger or experienced boatyard.

🧭 Performance and Handling

Sailors who install the 404TD report significant gains in sail efficiency, thanks to the longer luff and lower tack position. The hidden drum reduces clutter on the bow, improving safety during anchoring and sail handling. Despite its compact design, the 404TD maintains the smooth furling action and low friction operation that define the Furlex brand.

It’s especially popular among offshore cruisers, expedition yachts, and performance sailors who demand both strength and elegance in their rigging.

🛠️ Ideal Applications

The Furlex 404TD is best suited for:

• Bluewater cruising yachts (50–65 ft)
• Expedition and offshore vessels
• Performance cruisers seeking longer luff length
• Yachts with bow lockers or anchor compartments
• Owners upgrading from above-deck furlers

🧾 Final Thoughts

The Furlex 404TD is the ultimate through-deck furling solution for large yachts. By combining robust engineering with a clean deck layout and enhanced sail geometry, it delivers the kind of performance and reliability that offshore sailors demand.

Whether you're refitting a seasoned passagemaker or outfitting a new build, the 404TD offers the thoughtful design and proven durability that make sailing smoother, safer, and more rewarding.
