WATERCRAFT
The invention relates to a watercraft comprising an at least partly elastic and preferably inflatable casing ( 1 ), in particular a casing which surrounds an inner region. The watercraft has a base ( 2 ), an energy storage device ( 6 ), and a drive device which is secured to the base and comprises a drive unit ( 4 ) that is located in the water during operation, the flow of water produced by the drive unit during operation being controllable by means of a controller. The drive device is releasably secured to the base as a module comprising the energy storage device ( 6 ), which is designed as part of the module, such that the module can be removed as a structural unit.
1 . A watercraft comprising:
an at least partly elastic casing;
a base;
an energy storage device; and
a drive device which is secured to the base and comprises a drive unit that is located in water during operation, the flow of water produced by the drive unit during operation being controllable by means of a controller,
wherein the drive device is releasably secured to the base as a module comprising the energy storage device, which is designed as part of the module, such that the module can be removed as a structural unit.
2 . The watercraft as claimed in claim 1 , wherein the module has at least one upper base profile body designed for fixing to the base.
3 . The watercraft as claimed in claim 2 , wherein the module is secured to the base by at least two base profile bodies.
4 . The watercraft as claimed in claim 1 , wherein the base is inflatable.
5 . The watercraft as claimed claim 1 , further including a recess which is at least partially filled with water during operation, in the base, into which recess the drive unit can be introduced in order to reduce the depth of the watercraft.
6 . The watercraft as claimed claim 1 , further including a holding device, via which the drive unit is movable.
7 . The watercraft as claimed in claim 6 , wherein the holding device of the drive unit is arranged height-adjustably in a guide of the module.
8 . The watercraft as claimed in claim 1 , wherein the energy storage device is formed by a receptacle as an exchangeable part of the module.
9 . The watercraft as claimed in claim 1 , wherein the casing of the watercraft completely comprises an elastic impact zone.
10 . The watercraft as claimed in claim 1 , wherein the drive unit is arranged centrally.
11 . The watercraft as claimed in claim 1 , wherein the casing has an at least substantially polygonal or round outer contour.
12 . The watercraft as claimed in claim 1 , wherein the control device has at least one sensor unit, which receives an input signal for controlling the drive unit, and a control unit for generating a control signal to the drive unit.
13 . The watercraft as claimed in claim 12 , wherein the sensor unit comprises a gyroscope and/or a wireless or wired hand controller.
14 . The watercraft as claimed in claim 1 , wherein the control device has a steering unit designed for manual actuation.
15 . The watercraft as claimed in claim 1 , wherein the drive device has a dead man's switch.
16 . The watercraft as claimed in claim 1 , wherein the drive unit comprises an impeller arranged in a flow duct.
17 . The watercraft as claimed in claim 1 , wherein the at least partly elastic casing is inflatable.
18 . The watercraft as claimed in claim 1 , wherein the at least partly elastic casing surrounds an inner region.
19 . The watercraft as claimed in claim 4 , wherein the base is arranged on the inside of the casing and is provided with inner connecting elements which, spaced apart from the edge of the base, connect the top side and base inner side of the base to each other.
