Definitions
- the invention relates to a trim ballast for Sailing boats according to that of claim 1.
- Such a trim ballast is used in particular High performance sailing boats used the regattas and especially sea regattas.
- the sailboat points here a hull, a mast and a keel, whereby the trim ballast as streamlined, parallel to the Ballast body aligned in the longitudinal direction of the sailboat is formed, which has approximately the shape of a torpedo and connected to the keel.
- On both long sides of the Ballast bodies are transverse to the longitudinal direction of the sailboat aligned stabilizing fins provided.
- This Stabilizing fins are usually one Straight ahead of the sailboat without heeling approximately parallel to the water surface, but also Stabilizing fins are possible that have a certain Take up the angle of attack against the water surface.
- the trim ballast with the stabilizing fins serves in particular, to excessive heeling of the boat too prevent because of the weight of the trim ballast and due to the stabilizing fins a counter torque at Cranks of the sailboat is built. In contrast to Sailing boats without such a trim ballast this reduces the heel of the sailboat so that Driving maneuvers with smaller curve diameters also with strong winds are possible.
- the invention has for its object a trim ballast of the kind in question with which the Sailing properties of a sailboat, especially one Ocean yacht, to be further improved.
- Ballast body at least in the area in which the Stabilizing fins are arranged around its longitudinal axis swivel design.
- the ballast or the area containing the stabilizing fins regardless of the heel of the sailboat, always in one aligns essentially the same reference position.
- the stabilization fins are the reference position mirror-symmetrical to the through the longitudinal axis of the Ballast body perpendicular plane. This means that the ballast body at least in the area of Stabilizing fins the heels, i.e. inclinations of the sailboat does not participate, but in his Reference position remains. If e.g. the stabilizing fins stand perpendicular to the plumb plane, and upright Straight travel of the sailboat with its surface lie parallel to the water surface, then keep them Stabilizing fins even with a heel, i.e. one Inclination of the sailboat parallel to this position Water surface at.
- the alignment of the trim ballast or the area of the Trim ballast with the stabilizing fins automatically e.g. in that the weight distribution of the Ballast body is designed so that its focus is below the longitudinal axis of the ballast body to the this is pivoted, with "below” that of Side of the longitudinal axis facing away from the water surface is.
- the storage of the swiveling area of the Trim ballast opposite the keel should of course go through low bearing friction are supported.
- the Ballast body points at least in the area of the storage preferably a rotationally symmetrical cross section, making easy pivoting storage and connection with the keel is reached.
- the ballast body can consist of several in the longitudinal direction adjoining sections can be constructed, whereby a section that carries stabilizing fins and swivels is connected to the keel of the sailboat, whereas the other sections are firmly attached to the keel.
- ballast body It is independent of the construction of the ballast body possible, the ballast body or the section with the Stabilizing fins against another construction other dimensions of the stabilizing fins exchange, e.g. the sailing characteristics of the Sailboat to appropriate meteorological conditions adapt. This is for ballast bodies that are firmly attached to the Keel connected, not possible.
- the stabilizing fins of the trim ballast a transverse axis of the ballast body is designed to be pivotable, so that their angle of inclination with respect to the longitudinal axis of the Ballast body is adjustable.
- the stabilizing fins can e.g. with the help of one inside the ballast body located swivel gear can be adjusted.
- This Part-turn gearbox can be operated using actuators, e.g. in the keel running racks from the crew of the sailboat can be operated mechanically. There is also a remote control via a separate drive, e.g. an electric drive possible.
- the trim ballast has only one streamlined ballast directly connected to the keel on.
- the trim ballast has only one streamlined ballast directly connected to the keel on.
- several, e.g. two Ballast body to provide symmetrical to the median plane the boat and the keel over one each Support structure are connected. In this case, they are both Ballast body or at least the stabilizing fins contained areas pivotable.
- a sailing boat 1 is shown schematically, the has a hull 2, a mast 3 and a keel 4. With the keel 4 is connected to a trim ballast 5, one has streamlined ballast body 6 on his both long sides transverse to the longitudinal direction of the sailboat aligned stabilizing fins 7.
- the water surface is indicated by reference number 8; the sailboat 1 lies with about half of its hull 2, the keel 4 and the trim ballast 5 below the Water surface 8.
- the generally torpedo-shaped ballast body 6 is at least in the area of the stabilizing fins 7 in cross section rotationally symmetrical and there has two in Circumferential direction of the ballast body 6 bearing seats 9 which e.g. are formed as grooves. Every camp seat 9 is encompassed by a bearing shell 10 which is fixed to the Keel 4 is connected. Bearing seat and bearing shell form one Bearings; if necessary, between the bearing seat and the bearing shell Roll elements 11 may be located, e.g. Balls or needle rollers.
- the bearing shells 10 can e.g. be made in two parts, around the ballast body quickly against another one To be able to replace ballast bodies.
- the ballast body 6 is thus about a longitudinal axis 12 opposite the keel and the longitudinal direction of the sailboat pivotable.
- the horizontal stabilizing fins 7 lie approximately at the level of the longitudinal axis 12; however, they can like dashed in figure and designated 7 'also in one certain angle of inclination against this horizontal plane be arranged.
- the ballast body 6 is designed to be Center of gravity S lies below the longitudinal axis 12. This can e.g. by an additional ballast element 13 on the Bottom of the ballast 6 can be reached.
- the trim ballast 5 remains with its ballast body 6 in the original position towards the water surface.
- the ballast body 6 in several sections 6-1, 6-2 and 6-3 can be divided, the join together.
- the middle section is 6-2 provided with the stabilizing fins 7 and the other two front and rear sections 6-1 and 6-3 pivotally connected about the longitudinal axis.
- Sections 6-1 and 6-3 are firmly connected to the keel 4, whereas the Section 6-2 with the keel 4 can be pivoted as explained above connected is.
- FIGs 4 and 5 is an embodiment of the Trim ballast or ballast body 6 shown in the the stabilizing fins 7 still about a transverse axis 21 of the Ballast body are pivotable.
- the Stabilizing fins 7 carries.
- a swivel gear 22 located that a gear shaft 23 in the direction of the transverse axis 21 has.
- This gear shaft 23 is with a Swivel lever 24 connected to the control rod 25 to the transverse axis 21 is adjustable.
- the pivot lever 24 can as shown in Figure 5, on its front and back be guided by circular guides 26 and 27. Other Refinements are possible.
- the sailboat builds up a counter-moment, which strives turn the sailboat back towards the plumb plane.
- the counter moment is determined by the weight of the Ballast body and through to the stabilizing fins acting flow forces determined.
- the flow forces are characterized by the "effective" effective area of the Stabilizing fins, that is the one on the water surface projected area.
- FIG. 6 shows that the effective effective area f the stabilizing fins on one with the keel 4 connected trim ballast when heeling the sailboat depending on the heel angle a at a corresponding one Wind power is on the sail of the boat.
- wind power is the effective effective area F at an automatically aligning trim ballast according to the Invention larger, namely the same when driving upright surface of the sailboat, so that the same Wind power the heel of the sailboat is less like indicated by b, and therefore the sailboat better maneuverable and also faster when cornering is sailing.
