Abstract

The trimming-keel (1) for ballast transfer to windward, partic. for wind-propelled watercraft, is pivoted (2) underneath or just inside the hull, allowing it to be tilted transversely. Mechanical, hydraulic or electrical means (4), or a combination of these, are provided to produce this movement. A gasket (3) may seal the keel-aperture in the hull, alternatively a watertight deck may be fitted above the entire assembly. If the keel is of the retractable-centreboard form, the housing may be mounted tiltably instead of the keel.

Description

Trimmkiel für Trim keel for

windqetriebene Wasserfahrzeuge Die Erfindung betrifft einen Trimmkiel zur Verlagerung des Ballastes nach Luv insbesondere für windgetriebene Wasserfahrzeuge. Wind-powered watercraft The invention relates to a trim keel for shifting the ballast to windward, especially for wind-powered watercraft.

Windgetriebene Wasserfahrzeuge müssen sich auf Grund ihrer Form-und Gewichtsstabilität erst lo bis 20 Grad krängen, bevor sie der aus dem Wind entstehenden Querkraft eine ausreichende Gegenkraft entgegensetzen können.Wind powered watercraft must be based on their shape and shape Heel weight stability only lo to 20 degrees before it comes out of the wind Be able to counteract a lateral force with a sufficient counterforce.

Zweck der Erfindung ist es, diese Krängung mit Hilfe des Trimmkiels durch Verlagerung des Ballastes nach Luv, wodurch ein zusätzliches aufrichtendes Moment entsteht, auf ein Minimum zu beschränken bzw. mehr Segelfläche bei weniger Krängung zu ermöglichen.The purpose of the invention is to heel this with the help of the trim keel by shifting the ballast to windward, creating an additional righting Moment arises to limit to a minimum or more sail area with less Allow heeling.

Stand der Technik ist der feste oder aufholbare Ballastkiel, der jedoch nicht in Querrichtung beweglich ist. Eine gewisse Ähnlichkeit mit vorliegender Erfindung wäre u. U. in den Offenlegungsschriften 1556489 und 2254205 zu finden. Sie dienen aber beide einem anderen Sinn und Zweck.The state of the art is the fixed or retrievable ballast keel, however cannot move in the transverse direction. Some similarity to the present invention could possibly be found in Offenlegungsschriften 1556489 and 2254205. You serve but both have a different purpose.

Der Erfindung liegt die Aufgabe zugrunde, ohne Verminderung der Sicherheit (aufrichtendes Moment) die Leistungsfähigkeit und den Komfort (mehr Segel = mehr Geschwindigkeit und weniger Krängung a mehr Komfort) insbesondere von windgetriebenen Wasserfahrzeugen zu erhöhen.The invention is based on the object without reducing security (righting moment) the efficiency and the comfort (more sail = more Speed and less heel a more comfort) especially of wind-driven ones Increase watercraft.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ballast durch den Trimmkiel nach Luv verlagert wird.This object is achieved according to the invention in that the ballast is shifted to windward by the trim keel.

Die mit der Erfindung erzielbaren Vorteile liegen insbesondere darin, daß die Leistungs- und Komfortsteigerung mit dem ohnehin notwendigen Ballast erreicht wird.The advantages that can be achieved with the invention are, in particular, that the increase in performance and comfort is achieved with the ballast that is necessary anyway will.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben: Der Trimmkiel (1) ist an der Unterseite des Rumpfes gelagert (2) und mit einer Manschette (3) abgedichtet. Die Trimmvorrichtung (4), in diesem Fall eine Hydraulik, trimmt den Kiel in die gewünsche Richtung, so daß der Ballast jeweils in Luv liegt.An embodiment of the invention is shown in the drawing and is described in more detail below: The trim keel (1) is on the underside of the fuselage stored (2) and sealed with a sleeve (3). The trimming device (4), in this case a hydraulic system, trims the keel in the desired direction, see above that the ballast is always in windward direction.
