DETAILED DESCRIPTION

[0025] FIG. 1 shows a device 1, especially integrated in a hull of a boat, as shown in example in FIG. 3, for producing a stern wave as part of on a watercraft, which is not shown, in particular a sports boat, for wakesurfing and/or wakeboarding on the stern wave of the watercraft, comprising at least one pivoting deflector 3 which can be pivoted out laterally, having an arrangement means 21, in particular hinge means, on a lateral hull region 4 of the watercraft, in particular in the region of the stern 5, wherein a stern wave for wakesurfing and/or wakeboarding can be formed by the pivoting deflector 3 in the pivoted-out state and an integration region 6 for the pivoting deflector 3 in the lateral hull region 4 of the watercraft 2, such that the pivoting deflector 3 is substantially integrated in the lateral hull region 4 of the watercraft 2 in pivoted-in stage, to adapt and/or continue a hull outer line 8 in the lateral hull region 4 of the watercraft 2, wherein the pivoting deflector 3 is fully integrated in the lateral hull region 4 in the pivoted-in stage 7, as exemplarily in FIG. 2, whereas for lateral pivoting a actuating means 13 is provided, especially a linear cylinder 14, as presented I FIG. 3, and/or a volumetrically variable bellows cylinder 15, which is provide at the hull region 4 and the pivoting deflector 3 is pivotable in a pivoting angle 19 of up to about 45.

[0026] FIG. 2 shows a device for producing a stern wave in a pivoted-in stage; wherein the pivoting deflector 3 is folded into the integration range. The pivoting deflector 3 is positioned at a lateral height 9 in such a way that the water line 10 at the lateral hull region 4 depends on height parameters, in particular the state of loading and/or filling of ballast tanks, arranged essentially between an upper edge 11 of the pivoting deflector 3 and a lower edge 12 of the pivoting deflector 3 the actuating means 13. In a deeper state of loading the water line 10 can perform as the water line 10, the upper edge 11 of the pivoting deflector 3 provided reaching up to the upper edge 18 of the hull region 4.
