Description

[0028] Preferred embodiments of the invention are described in greater detail on the basis of the drawing hereafter. In the figures:

[0029] FIG. 1 shows a watercraft according to the invention;

[0030] FIG. 2 shows the watercraft from FIG. 1 having the floats in a middle position;

[0031] FIG. 3 shows the watercraft from FIG. 1 having the floats in an end position;

[0032] FIG. 4 shows a watercraft from below;

[0033] FIG. 5 shows a schematic illustration of the kinematic connection.

[0034] FIG. 1 to FIG. 3 showin various positionsa watercraft 10 having a hull 4 and two floats 5 arranged on both sides of the hull 4, which are connected to the hull 4 in each case via a kinematic connection 6.

[0035] The kinematic connection 6which is also schematically shown in FIG. 5 for a single float 5comprises a first leg 1, which is linked at one end on the hull 4 and at the other end on the float 5 and is variable in its length by a first actuator 11 (mechanism for distance change).

[0036] The kinematic connection 6 of the illustrated preferred embodiment furthermore comprises a second leg 2, which is linked at one end on the hull 4 and at the other end on the first leg 1 and is variable in its length by a second actuator 12. Alternatively, the second leg 2 can also be linked on another leg, which extends between hull 4 and float 5, for example, the third leg 3 described hereafter. The linkage point 14 of the first leg 1 on the hull 4 is spaced apart from the linkage point 15 of the second leg 2 on the hull 4. The second leg 2 forms a pivot mechanism, using which the float 5 is pivotable in relation to the hull 4.

[0037] The kinematic connection 6 of the illustrated preferred embodiment furthermore comprises a third leg 3, which is linked at one end on the first leg 1 (alternatively: on the hull 4) and at the other end on the float 5 and is variable in its length by a third actuator 13. The linkage point 8 of the first leg 1 on the float 5 is spaced apart from the linkage point 9 of the third leg 3 on the float 5.

[0038] In this case, the first leg 1 is pivotable in the linkage point 8 on the float 5 about a first pivot axis and the third leg 3 is pivotable in the linkage point 9 on the float 5 about a third pivot axis. The first pivot axis and the third pivot axis (both are transverse to the plane of the drawing of FIGS. 1-3) are essentially parallel to one another and are spaced apart from one another in a direction perpendicular to the first and third pivot axes (in parallel to the direction extending in the plane of the drawing). The float 5 can thus be tilted in relation to the hull 4 (tilt mechanism).

[0039] The linkage point 17 on the second leg 2 on the first leg 1 and the linkage point 16 of the third leg 3 on the first leg 1 are preferably arranged (directly) adjacent to one another (FIG. 5) or are entirely coincident (FIG. 1 to FIG. 3).

[0040] The linkage point of the first leg 1 on the hull 4 is arranged in a lateral region of the hull 4.

[0041] While in FIG. 1, the floats 5 are pivoted outby the second actuator 2and/or are arranged adjacent to the hull 4 and in FIG. 2 they are located in the middle position, in FIG. 3 they are arranged below the hull 4. In FIG. 3, the floats or booms are directly adjacent to one another and form a shared compact envelope, whereby a type of monohull is formed.

[0042] The actuators 11, 12, 13 are preferably actuable independently of one another. In the illustrated embodiment, they represent cylinder drives. The first actuator 11 and/or the third actuator 13 are preferably designed as telescopic cylinders, so that the distance to the hull 4 is variable to a large extent.

[0043] In the embodiment according to FIG. 4, the floats 5 are each connected to the hull 4 via two kinematic connections 6, which are spaced apart from one another in the travel direction 7 of the watercraft 10. In this variant, the oblong floats 5 can be essentially parallel to one another and/or to the travel direction 7 of the watercraft 10 in a first position (solid line) and can preferably extend toward one another in a V shape in the travel direction 7 of the watercraft 10 in a second position (dashed line). A position in which the floatsviewed in the travel directionextend away from one another would also be conceivable. This is achieved in that the kinematic connections 6 of the first legs 1 thereof in particular are actuated to different extents.
