Definitions

  • the invention relates to a device for avoiding or at least reducing disturbing noises on sailing yachts with a relatively wide transom and lines running flat to the mirror, in particular for sailing yachts with aft cabin.
  • the invention is therefore based on the object of preventing such noise or at least reducing it to such an extent that aft cabins can be used.
  • the damping mat according to the invention which is arranged at the stern so that it lies at least partially above the water line, ensures that the waves first hit the damping mat.
  • the sudden, hard impact becomes a compliant, relatively soft impact.
  • the damping effect of the mat can be achieved with the aid of an air or gas filling or by mats which consist entirely or partially of plastic foam and / or fibers.
  • the casing provided according to claim 3 also allows the use of soft plastics which are particularly flexible but have low strengths.
  • the desired damping effect can also be achieved with the help of fibers.
  • the fibers can act in two ways. One effect is damping due to compliance. The other effect can be caused by the surface structure of the fiber mats when they come into direct contact with the waves.
  • the attachment of the damping mat according to the invention is facilitated according to claim 4 by an incision for the rudder.
  • the mat can be easily pulled under the stern with the help of a line, enclosing the oar.
  • the rudder secures the damping mat in the position required for the damping function.
  • a multi-part damping mat is also advantageous, so that the mat can be folded or assembled. This makes it easier to stow the mat after using it.
  • the damping mat is provided with thimbles according to claim 7 at the edges.
  • the mat can be leashed on the thimbles.
  • the damping mat is designated 2.
  • the lower half of the mat shown consists of an air and water impermeable fabric, for. B. a rubberized part, or a plastic tarp or film.
  • the plastic tarpaulin can be reinforced by an inserted fabric.
  • a suitable valve for air filling is attached to one of the mat halves.
  • the damping mat 2 has two air chambers 5 and 6.
  • a valve belongs to each closed air chamber.
  • an underlying tarpaulin 8 and an overhead tarpaulin 7 are provided.
  • the embodiment of Figure 2 differs from that of Figure 1 by plastic foam mats 9 and 10.
  • the plastic foam mats 9 and 10 form inserts.
  • a closed-cell, water-impermeable polystyrene foam is used as the plastic foam.
  • the flexibility of the plastic foam can be adjusted with its density. Depending on the density, there is a larger or smaller density. In the exemplary embodiment, the density is 30kg / m3 foam.
  • the damping mat 2 is provided with thimbles 18 and 19 at the edges.
  • Special, projecting tabs 20 are provided for the thimbles 19.
  • an incision 26 is provided in the damping mat 2, which serves to pull the damping mat forward from the aft beyond the rudder.
  • the mat halves shown in Figure 1 include the rudder.
  • the incision 26 limits the pulling forward of the damping mat 2 or the damping mat 2 is secured in its functional position.
  • the damping mat can be produced, for example, in three different types, namely for ships up to 8 m, for ships from 8 m to 12 m and for ships from 12 to 15 m.
  • the different sizes of the damping mats are determined by the dimensions 22, 23, 24 and 21.
  • the dimension 22 180 cm
  • the dimension 23 56 cm
  • the dimension 24 100 cm.
  • the mat thickness is 1 to 3 cm.
  • the attachment of the damping mat 2 is explained in Figure 3.
  • a tail 1 is shown with the mirror tilted forward in the cutout.
  • the damping mat 2 has been pulled and fixed under the rear 1 with lines 3.
  • the damping mat 2 includes the rudder 25.
  • the waterline of the ship is designated 4 and touches the damping mat approximately in the middle. It can be seen that waves that run under the rear 1 hit the damping mat 2, which prevents an annoying hitting noise.
