Abstract

The system is for setting the foresail (1) on a sailing boat, to enable it to point higher into the wind when sailing close-hauled. The mainsail (2) is set on the mast and the boom in the usual way. The foresail or genoa is hoisted by a halyard (6) whose lower end is attached to a traveller sliding on a curved traveller rail (3) on the foredeck of the boat. When the boat is sailing close-hauled, the traveller is hauled to the windward end of the curved rail to optimise the setting of the genoa. There are tackles (4,5) on the port and starboard sides of the boat for this purpose.

Description

Problem

Um die Vortriebs-Wirkung der Vorsegel und die Höhe bei Am-Wind-Kursen zu verbessern, ist es aus strömungstechnischen Gründen vorteilhaft, den unteren Anschlagpunkt des Fockstags bzw. Rollgenuastags Richtung Luv zu verlagern. Um dies zu erreichen, sind diverse Rigg-Techniken entwickelt worden, z. B. ein mit dem Großbaum verschwenkter Fockbaum oder die Eindrittel/zweidrittel-Fock mit integriertem Fockbaum. Diese Rigg-Techniken erfordern hohen technischen Aufwand.To the propelling effect of the headsail and the height at upwind courses too improve, it is advantageous for fluidic reasons, the lower To shift the anchor point of the jib day or furling genoa day towards the windward. To do this To achieve this, various rig techniques have been developed. B. with the large tree swiveled jib boom or the one-third / two-third jib with integrated jib boom. These rigging techniques require a lot of technical effort.

Es ist auch bekannt, daß eine luvseitliche Versetzung der Vorsegel bei Regatten wegen der verbesserten Vortriebsleistung am Wind nicht zugelassen ist.It is also known that a windward displacement of the headsail at Regattas are not permitted due to the improved propulsive power on the wind.

solution

Als einfache und preiswerte Lösung wird vorgeschlagen, den Anschlagpunkt des Fockstags bzw. Rollgenuastags auf einen Traveller zu verlegen, der quer zur Längsachse des Rumpfes kurz hinter dem Bug montiert ist, und diesen nach jeder Wende nach Luv zu verlagern (siehe Zeichnung 1). Der Traveller muß stabil genug sein, um die Spannung und die Zugkräfte des Vorlieks auch bei hohen Windstärken aufzunehmen.As a simple and inexpensive solution, the attachment point of the Fockags or Rollgenuastags to be laid on a traveler who is transverse to the Longitudinal axis of the fuselage is mounted just behind the bow, and this after each Turn to windward shift (see drawing 1). The traveler must be stable be enough to withstand the tension and traction of the luff even at high Record wind strengths.

Mittels Seilzügen an Steuerbord und Backbord, die auf Winschen im Cockpit führen, kann der Traveller verlagert werden (siehe Zeichnung 1 und 2). Weil der Genua- bzw. Fockstags beim seitlichen Versetzen immer die gleiche Spannung bzw. die gleiche Länge behalten soll, muß die Travellerschiene eine genau berechnete Bogenform erhalten.With cables on starboard and port, which are on winches in the cockpit the traveler can be relocated (see drawings 1 and 2). Because the Genoa or jib tags always have the same tension when moving to the side or keep the same length, the traveler rail must be exactly Get calculated arc shape.

Claims

1. Rigging device that allows the lower anchor point of a Jib or roll genoa days and transversely to the longitudinal axis of the yacht to shift in the direction of windward without increasing the headsail tension change.

2. Rigging device according to claim 1, characterized in that a Traveler transverse to the longitudinal axis of the yacht (bow traveler) with the necessary Distance to the mast-supporting forestay is anchored on deck, at which the lower end of the furling genoa day or jib day is posted, so that the luff and the Bottom of the foresail after every turn in the most aerodynamic windward position can be brought (see drawings 1 and 2).

3. Rigging device according to claim 1 and 2, characterized in that that the traveler rail is guided in the arc, so that the tension or The length of the genoa day or jib day is the same in every position of the traveler remains and thus the luff of the sail is optimally tightened. (Please refer Drawing 1).

4. Rigging device according to claim 1 to 3, characterized in that that the traveler on the curved rail with pulleys, lines with Pulley blocks and winches from the cockpit upwind after every turn can be pulled into the middle position and any other position and fixed in it (See drawing 1).
