Tacking the sail at deck level allows for a longer luff length of your foresail. You will improve sailing performance without compromising the convenience of the jib furling system. The bow will also be less cluttered as the line drum is hidden below the deck. The free turn of the tack swivel is the same as in all other Furlex models; a necessity to reduce the furling resistance and to flatten out a reefed genoa. The MkII version of Furlex TD (Through Deck) has all the benefits developed for the standard 4th generation Furlex, such as, smooth furling with roller bearings combined with stainless ball bearings for the drum and an optional rigging screw to adjust the forestay length. In addition, the outside diameter of the line drum is smaller than on earlier TD models which simplifies installation in narrow anchor boxes and allows for installation further forward.
The kit requires that the wire is cut to length and fixed with a ‘Sta-lok’ mechanical wire locking system. A completely integrated rigging screw is offered as an option. It allows for adjustment of the forestay length without altering the height of the tack attachment. You can choose the Forestay Diameter, Max. Length and the type of termination, either Standard Sta-lok terminal or a Sta-lok terminal & rigging screw.

The Furlex 204TD is Seldén’s through-deck variant of its popular 204S furling system, designed for yachts up to 9 tonnes displacement. By relocating the furling drum below deck, the 204TD offers a cleaner bow layout, longer luff length, and improved sail performance—without sacrificing the reliability and smooth operation that Furlex systems are known for.
Whether you're optimizing your rig for performance or simply want a tidier foredeck, the 204TD delivers a smart, integrated solution.
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 performance—especially upwind.
The MkII version features a smaller drum diameter than earlier models, making it easier to install in narrow anchor lockers and allowing placement further forward for optimal geometry.
Like all Furlex systems, the 204TD includes a free-turning tack swivel, which reduces furling resistance and helps flatten the sail when reefed—critical for maintaining sail shape and pointing ability.
The system uses a combination of roller bearings and stainless steel ball bearings in the drum and swivel, ensuring smooth furling under load and long-term durability.
An integrated rigging screw is available, allowing forestay adjustment without altering the tack height—ideal for tuning mast rake or sail tension.

The Furlex 204TD is delivered as a complete installation kit, including:
Installation requires access to the anchor locker or bow compartment and is best performed by a professional rigger or experienced boatyard.
Sailors who install the 204TD report noticeable improvements in sail efficiency, thanks to the longer luff and lower tack position. The hidden drum also reduces clutter on the bow, making anchoring and sail handling safer and more streamlined.
Despite its compact design, the 204TD maintains the smooth furling action and low friction operation that define the Furlex brand. It’s especially popular among performance cruisers and owners of newer production yachts designed with through-deck systems in mind.
The Furlex 204TD is best suited for:
The Furlex 204TD is a sleek, high-performance solution for sailors who want the benefits of electric-free furling with a cleaner deck layout and improved sail geometry. With its compact drum, robust bearings, and complete kit, it’s a smart upgrade for mid-sized yachts looking to maximize headsail efficiency.
Whether you're refitting your rig or outfitting a new build, the 204TD offers the kind of thoughtful engineering and proven reliability that makes sailing smoother and more rewarding.
