DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/DE 94/00060 filed Jan. 21, 1994 and based upon German application P 43 16 538.9 of 18 May 1996 under the International Convention.
FIELD OF THE INVENTION
The invention relates to a watercraft with a buoyancy hull and a passenger stand or the like secured thereon, whereby a ballast body is optionally mounted on the buoyancy hull by means of a support frame. The buoyancy hull or the support frame can have rigid support areas on both sides transversely to its longitudinal direction, the passenger stand being preferably equipped with a seat and a handlebar, whereby the handlebar is coupled to a steering system of the watercraft and on the support areas, holding elements are provided capable of accommodating the feet and possibly the calves of the passenger.
BACKGROUND OF THE INVENTION
A watercraft is known for instance from EP 0 387 253 B1. In the known device the passenger stand is linked to the buoyancy hull via supports, primarily located underneath the actual buoyancy hull. This design is not satisfactory from the construction point of view, since it requires that the buoyancy hull be traversed by the supports, which makes the entire construction very expensive. Besides the watercraft is also relatively complicated to handle.
OBJECT OF THE INVENTION
It is the object of the invention to create a watercraft of the aforedescribed kind with a simple construction and which can be easily handled.
SUMMARY OF THE INVENTION
In order to achieve this object the passenger stand is on at least one slide guide on the upper side of the buoyancy hull transversely to the longitudinal axis of the watercraft, so as to be movable along this slide guide.
It is particularly advantageous to provide the slide guide as at least one guide rail running transversely to the median longitudinal axis of the watercraft. The rail preferably is curved like an arc of a circle with a center of curvature in a vertical median plane which is formed by the median cutting plane of the watercraft, namely either between the guide rail and the boat keel or ballast body or in the boat keel or the ballast body or advantageously beyond the boat keel or the ballast body. The the passenger stand can be moved along the guide rail by means of rollers.
As a result of this construction it is possible to shape the buoyancy hull like a boat body which does not have to be traversed by supports or similar elements, but wherein the sliding of the passenger stand required for counterbalancing the motions of the buoyancy hull caused by waves can take place in a simple manner along the slide guide arranged on the upper side of the watercraft or the buoyancy hull. Thereby the construction costs are minimized and the handling is considerably simplified. The slide guide can consist of a bow curved like an arc of a circle, or of several spaced-apart bows arranged so that in a normal upright position of the buoyancy hull or the boat body the highest point of the curvature lies in the vertical median plane of the buoyancy hull or boat body. Instead of a bulge shaped like an arc of a circle an elliptical bulge or the like can be provided. However the shape of the arc of a circle is preferred.
Instead of a rigid mounting of the slide guide on the buoyancy hull or boat body, it is possible to have an adjustable mounting of the slide guide on the buoyancy hull or the boat body, whereby the adjustment can be performed during travel by means of actuators, for the purpose of adjustment to changeable influencing factors such as the motions of the sea, speed, travel direction or the like. The invention provides a watercraft wherein the person or persons using the watercraft can maintain themselves and the decoupled superstructure in active equilibrium, in an ergonomic and easily controllable manner, while the buoyancy hull is exposed to the motions of the waves.
According to a feature of the invention, a rear part of the passenger stand seen in the travel direction can have a driving u
