Abstract

A yacht which is luffing has a certain angle of heel depending on wind strength, trimming crew, and the keel weight. This has an adverse effect on the speed, and furthermore a trimming crew can only be used to a limited extent. The centreboard is intended to create a windward ballast which reduces the heeling of the sailing yacht, can be used constantly and is independent of the number of crew members, so that a higher speed of the yacht is made possible. In small sailing yachts, one centreboard each is mounted on the port and starboard side; in larger yachts, two or more centreboards each are mounted. Each centreboard is pivotable in all directions and it can be extended and filled gradually with water. The function of the centreboards is based on the principle of a crew trimming on the trapeze. The centreboard is suitable for keel boats, cabin boats, cruisers, yachts and also for catamarans and trimarans for shorter and longer turns.

Description

Es ist bekannt, daß Segelyachten je nach Windstärke eine bestimmte Krängung aufweisen. Bei zu großer Krängung wird die Geschwindigkeit vermindert oder die Gefahr einer Kenterung besteht. Es ist ferner bekannt, daß der notwendige Trimm durch den Luvballast erreicht wird, das kann sein, der Bleikiel, die austrimmende Crew oder der Wasserballast in Form eines Tanks, der im Rumpf der Yacht einge­ baut ist. Bei allen Arten des Trimmes, die auch kombiniert werden, reicht der Luvballast nur bis zu einer bestimmten Windstärke (Beaufort) aus, danach muß gerefft werden.It is known that sailing yachts have a certain heel depending on the wind strength exhibit. If the heel is too large, the speed is reduced or the There is a risk of capsizing. It is also known that the necessary trim can be reached by the windward ballast, which can be the lead keel, the balancing one Crew or the water ballast in the form of a tank, which is turned into the hull of the yacht is building. For all types of trim, which are also combined, it is sufficient Windward ballast only up to a certain wind strength (Beaufort), after that must be reefed.

Bei 5,5 bis 6 Beaufort am Wind ist die höchste Belastung erreicht, der Winddruck auf die Segel ist dann so hoch, daß das Gewicht des Bleikiels nicht mehr den nöti­ gen Gegendruck besitzt. Auch die austrimmende Crew, die ohnehin nur bei kurzen Törns in Küstennähe eingesetzt werden kann, schafft dies nicht mehr, die Segel­ yacht wird eine Krängung über 40 Grad aufweisen. Viel kann auch ein Wasser­ ballasttank im Rumpf der Yacht nicht bewirken, da die Hebelwirkung zu schwach ist.At 5.5 to 6 Beaufort on the wind, the highest load is reached, the wind pressure on the sail is so high that the weight of the lead keel is no longer necessary has back pressure. Even the crew who are out, who are only on short ones anyway Cruises can be used near the coast, the sails no longer manage yacht will have a heel over 40 degrees. Water can do a lot Do not effect the ballast tank in the hull of the yacht because the leverage is too weak is.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, einen Luvballast zu schaffen, der die Krängung einer Segelyacht vermindert, stän­ dig einsetzbar ist, unabhängig von der Zahl der Crewmitglieder den nötigen Luvballast besitzt und damit eine höhere Geschwindigkeit der Yacht ermöglicht.The invention specified in protection claim 1 is based on the problem to create a windward ballast that reduces the heeling of a sailing yacht dig can be used regardless of the number of crew members Has windward ballast and thus enables a higher speed of the yacht.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in protection claim 1.

Mit der Erfindung wird erreicht, daß das Schwert ausgefahren und mit Wasser als Ballast gefüllt eine höhere Wirkung erzielt als herkömmliche Mittel. Je nach Wind­ richtung und Windstärke kann der Wasserballast erhöht oder gesenkt werden, das Schwert ausgefahren oder eingezogen und nach allen Luvrichtungen geschwenkt werden.With the invention it is achieved that the sword extended and with water as Ballast filled has a higher effect than conventional agents. Depending on the wind The water ballast can be increased or decreased in the direction and strength of the wind Sword extended or drawn in and swiveled in all windward directions become.

Die Vorteile der Erfindung sind eine Erhöhung der Geschwindigkeit, geringere Krängung der Segelyacht, kein ermüdendes Sitzen der Crew auf der Luvseite und der Einsatz auf Langstrecken.The advantages of the invention are an increase in speed, less Heeling of the sailing yacht, no tiring sitting of the crew on the windward side and use on long distances.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in the protection claim 2.

Die Weiterbildung nach Schutzanspruch 2 für die Anwendung von mehreren Schwertern auf jeder Bootsseite ermöglicht dem Skipper eine gleichmäßigere Trimmlage seiner Yacht.The further training according to protection claim 2 for the application of several Swords on each side of the boat allow the skipper a more uniform Trim position of his yacht.

Ein Ausführungsbeispiel wird anhand der Fig. 1 bis 3 erläutert. Es zeigen:An embodiment is explained with reference to FIGS. 1 to 3. Show it:

Fig. 1 das Schwert im eingefahrenen, eingeschwenkten und leeren Zustand, mon­ tiert an einer Yacht, Fig. 1, the sword in the retracted, swung-in and the empty state, mon advantage of a yacht,

Fig. 2 das Schwert im ausgefahrenen und ausgeschwenkten Zustand mit wasser­ aufgefüllten äußeren Kammern, Fig. 2, the sword in the extended and swung-out condition with water-filled outer chambers,

Fig. 3 mehrere Seitenschwerter an einer Yacht montiert, die Leeseite eingezogen, die Luvseite ausgefahren und ausgeschwenkt. Fig. 3 mounted several side swords on a yacht, the leeward side retracted, the windward side extended and swung out.

Bei einer Segelyacht werden an Back- und Steuerbord je zwei Schwerter auf einer dafür vorgesehenen Plattform (9) montiert. Die beiden Schwerter auf der Luvseite (in Fig. 3 auf der Steuerbordseite) werden durch ihre Gelenke (2) ausgeschwenkt, danach werden diese durch das im Inneren der Schwerter befindliche metrische Gewinde (3) ausgefahren. Anschließend werden je nach Lage der Yacht die einzel­ nen Kammern (7) über die Schlauchverbindung (4) gefüllt.In a sailing yacht, two swords are mounted on a dedicated platform ( 9 ) on port and starboard. The two swords on the windward side (in Fig. 3 on the starboard side) are swung out by their joints ( 2 ), then these are extended by the metric thread ( 3 ) located inside the swords. Then, depending on the location of the yacht, the individual chambers ( 7 ) are filled via the hose connection ( 4 ).

Die Talje (8) wird gespannt, da sonst die Gefahr des Abbrechens der Schwerter besteht. Bei einer Wende wird das in den Kammern (7) befindliche Wasser über die drei Ventile (5) gelenzt. Der Vorgang auf der Steuerbordseite wiederholt sich nun auf der Backbordseite, die nun Luvseite wird, wobei das symmetrische Profil (6) den geringsten Luftwiderstand in Fahrtrichtung besitzt.The Talje ( 8 ) is tensioned, otherwise there is a risk of the swords breaking off. At a turn, the water in the chambers ( 7 ) is drained via the three valves ( 5 ). The process on the starboard side is now repeated on the port side, which now becomes the windward side, with the symmetrical profile ( 6 ) having the least air resistance in the direction of travel.

Die Wirkungsweise der Schwerter beruht auf dem Prinzip einer am Trapez austrimmenden Crew.The action of the swords is based on the principle of one on the trapeze trimming crew.
