Für die Verbindung zwischen Stagwirbel und Mast stehen Laschen, Gabeln und T-Togglen zur Auswahl. Der Wirbel muss sich frei in Zugrichtung des Vorstages einstellen können, ohne das er am Mast streift oder das Fall beeinträchtigt wird.

Reefing system with profiled forestay (mounted on deck)
With these reefing systems, the forestay wire does not rotate and the tensile forces of the forestay are not transmitted via bearings. The ease of furling remains independent of the forestay tension. Fine adjustment of the forestay length is made via a threaded connection on the jib furler, which is enclosed by a short pipe coupling. This transmits the torque from the jib furler to the extrusion while the forestay wire remains fixed. Optionally, a shroud tensioner can be installed above the jib furler to allow a larger adjustment range and convenient length adjustment when the forestay is attached. An extended tube coupling encloses the shroud tensioner and transfers the torque from the jib furler to the profile, while the forestay wire remains fixed. Regardless of whether a short or long pipe coupling is used, the attachment point for the sail tack is as close to the deck as possible. When using the endless jib furler, this is particularly low, and even lower with the lower deck version.
Advantages:
- The tensile forces of the forestay do not act on the bearing
- Robust and extremely unobtrusive stainless steel design
- Endless jib furler available in four sizes (high reefing torque, easy-grip line, no overrunning as with a drum furler)
- Reefing system can be configured with standard or third-party profiles (e.g. for retrofitting existing profile systems with a new jib furler)
- Line run-out adjustable in 12 positions all round
- Attachment point for the sail tack close to the deck
- Integrated tack swivel for attaching the sail tack

Jib furler Endless S-Series
Halyard swivels are used in furling and reefing systems when the halyard of the headsail is to be guided in the mast. They prevent the halyard from wrapping around the forestay when the sail is furled by decoupling the rotation of the halyard. Halyard swivels slide over a profile insert on the forestay profile that is adapted to the profile geometry. The rotary movement of the profile is transferred to the attachment point of the sail head, whereby the sail is furled parallel to the forestay at the neck and head, preventing the sail from billowing in the head area.

BARTELS profile forestages
BARTELS profile forestays are made from high-quality aluminium profile segments that are joined together to form a stable forestay profile and installed around the forestay wire. The wire runs inside the profile and forms the central axis for the furling and reefing process. In D1 systems, the forestay wire rotates together with the extrusion, whereas in D2 systems the wire remains fixed and only the extrusion rotates. The sail is guided in the single, specially developed keder groove via a leech tape.
BARTELS forestay profiles are available in three sizes and are characterised by their unique design with only one keder groove - a concept that makes it much easier to change sails, as two keder grooves would prevent the halyard swivels from passing through. This solution was chosen over 40 years ago in order to optimise the aerodynamic shape and ensure an almost vortex-free flow of the sail. Our forestay profiles therefore guarantee a smooth furling and reefing process that also fulfils high performance requirements.
