In den Fig. 1 und 2 weist der Rumpf 1 eines Bootes einen Kiel 2 auf. Mit 3 sind beidseitig des Kiels 2 angeordnete Behälter bezeichnet. Die Behälter 3 sind zweckmäßigerweise aus einem flexiblen Kunststoff, z. B. Hypalon® oder Polyvinylchlorid, hergestellt. Die Behälter 3 sind im Wesentlichen quaderförmig ausgebildet. Sie sind in ihrer Höhe und in ihrer Länge größer als die Lateralfläche des Kiels ausgebildet. Wie insbesondere aus Fig. 2 ersichtlich ist, ist eine Oberseite O der Behälter 3 in Anpassung an den Rumpf 1 zum Behälterinneren hin gewölbt ausgebildet. Ferner ist eine dem Kiel 2 zugewandte Längsseite L der Behälter 3 von der Oberseite O her schräg nach außen abfallend ausgebildet. Die Behälter 3 sind mit Wasser 4 gefüllt. Das Wasser kann über (hier nicht gezeigte) verschließbare Öffnungen in bzw. aus den Behältern 3 gepumpt werden. Die Behälter 3 können (hier ebenfalls nicht gezeigt) mehrere Kammern aufweisen. Es können insbesondere Kammern zur Aufnahme von Luft vorgesehen sein. Solche Kammern weisen geeignete (nicht gezeigte) Ventile zum Befüllen mit Luft auf. Sie dienen der Einstellung des Auftriebs der Vorrichtung.In Figs. 1 and 2, the hull 1 of a boat has a keel 2 on. With 3 are on both sides of the keel 2 arranged container designated. The container 3 are suitably from a flexible plastic, z. Hypalon® or polyvinyl chloride, produced. The containers 3 are substantially cuboid educated. They are larger in height and in length formed as the lateral surface of the keel. In particular From Fig. 2 it can be seen, is a top O of the container 3 curved in adaptation to the hull 1 to the container interior educated. Further, a keel 2 facing longitudinal side L of the container 3 from the top O forth obliquely outwards sloping trained. The containers 3 are filled with water 4. The water can be closed (not shown here) Openings are pumped into or out of the containers 3. The containers 3 may (more not shown here) more Have chambers. It can in particular chambers for recording be provided by air. Such chambers have suitable (not shown) valves for filling with air. They serve the adjustment of the buoyancy of the device.

Wie insbesondere aus Fig. 2 ersichtlich ist, sind die Behälter 3 von einer Hülle 4 umgeben. Die Hülle 4 ist zweckmäßigerweise aus einem flexiblen Material, z. B. ebenfalls Hypalon®, hergestellt. Sie ist mit den Behältern 3 fest verbunden. Die Verbindung kann unlösbar, z. B. mittels Verschweißen oder Vulkanisieren erfolgen. Zweckmäßigerweise ist aber eine lösbare Verbindung vorgesehen, die beispielsweise mittels an der Hülle 4 und den Behältern 3 vorgesehene Kauschen und durch sie hindurch geführte Schäkel oder dgl. erfolgen kann. Die Hülle 4 erstreckt sich zweckmäßigerweise über die gesamte Länge der Behälter 3. Die Behälter 3 können an ihrer Unterseite U auch durch mehrere Ketten oder Seile verbunden sein. Die Hülle 4 ist in ihrem Umfang so bemessen, dass bei in eine zwischen den Behältern 3 gebildete Vertiefung 5 eingreifendem Kiel 2 stets ein Abstand A zum Grund G verbleibt. Diese Bedingung ist insbesondere dann erfüllt, wenn der Umfang der Hülle höchstens gleich der Summe der Umfänge der Behälter 3 ist. Zweckmäßigerweise ist der Umfang der Hülle 4 aber kleiner als die Summe der Umfänge der Behälter 3. So wird ein ausreichend großer Abstand A gewährleistet. Mittels Leinen 6 sind die von der Hülle 4 zusammengehaltenen Behälter 3 mit dem Rumpf 1 verbunden.As can be seen in particular from FIG. 2, the containers are 3 surrounded by a shell 4. The sheath 4 is expediently made of a flexible material, eg. Also Hypalon®, produced. It is firmly connected to the containers 3. The compound can be insoluble, z. B. by welding or vulcanizing done. Appropriately, but is one detachable connection provided, for example by means of the shell 4 and the containers 3 provided thimbles and Shackles or the like guided by them can take place. The sheath 4 expediently extends over the entire Length of the containers 3. The containers 3 can at their bottom U also be connected by several chains or ropes. The shell 4 is dimensioned in its circumference so that in a formed between the containers 3 recess 5 engaging Kiel 2 always a distance A to the bottom G remains. This condition is particularly true when the scope of the Envelope at most equal to the sum of the sizes of containers 3 is. Conveniently, the circumference of the shell 4 but smaller as the sum of the perimeters of the containers 3. Thus becomes one sufficiently large distance A guaranteed. By means of linen 6 are held together by the shell 4 container 3 with connected to the hull 1.

Die Funktion der Vorrichtung ist folgende:The function of the device is as follows:

Zum Transport können die aus einem flexiblen Material hergestellten Behälter 3 zusammengefaltet vorliegen.

It can also be done by means of a special Grundgeschirrs be attached to the base G.

Um eine grundberührungsbedingte Beschädigung von Booten bei tidenbedingten Wasserspiegeländerungen zu vermeiden, fährt das Boot mit seinem Kiel 1 in die Vertiefung 5 ein. Alternativ dazu kann die Vorrichtung auch unter den Rumpf 1 des Bootes gezogen werden. Sobald die Vorrichtung ordnungsgemäß unter dem Rumpf 1 des Bootes angeordnet ist, wird sie mittels der Leinen 6 am Rumpf befestigt. Bei einem tidenbedingten Trockenfallen wird der Rumpf 1 auf den Behältern 3 abgestützt. Es verbleibt dabei stets ein Abstand A des Kiels 2 zum Grund G. Das gilt insbesondere für die Periode des Trokkenfallens, bei der infolge des Wasserstands ein Schlagen des Kiels 2 auf den Grund G zu befürchten ist. To cause groundbreaking damage to boats to prevent tidal water level changes the boat with his keel 1 in the recess 5 a. alternative this can also be done under the hull 1 of the boat to be pulled. Once the device is properly under the hull 1 of the boat is arranged, it is by means of the linen 6 attached to the hull. In a tidal Dry traps the hull 1 is supported on the containers 3. It always remains a distance A of the keel. 2 to the ground G. This is especially true for the period of dry falling, when due to the water level hitting the Kiels 2 on the bottom G is to be feared.

Mit der vorgeschlagenen Vorrichtung wird auf relativ einfache und kostengünstige Art und Weise eine durch Berührungen des Rumpfs 1 am Grund G bedingte Beschädigung des Bootes vermieden.
