Description

DISPOSITIF DE PREVENTION DU CHAVIRAGE DES NAVIRES MULTICOQUES DEVICE FOR PREVENTING THE CAPPING OF MULTIHULL VESSELS
DESCRIPTIONDESCRIPTION
L'invention est relative à un dispositif pour la prévention du chavirage des navires du type multicoques, notamment des catamarans ou des trimarans, à propulsion à voile, à moteur ou autre moyen, du genre agissant en dessous de la surface de l'eau, apte, lorsque le navire atteint une gîte proche du seuil de chavirage, à passer de la position repos, où il ne gêne pas l'hydrodynamique du navire, à la position travail où il contrebalance l'action qui est à l'origine de cette situation.The invention relates to a device for preventing capsizing of multihull type ships, in particular catamarans or trimarans, powered by sail, motor or other means, of the kind acting below the surface of the water, able, when the ship reaches a heel close to the capsizing threshold, to pass from the rest position, where it does not interfere with the hydrodynamics of the ship, to the working position where it counterbalances the action which is at the origin of this situation.
Les dispositifs connus du genre en question mettent en oeuvre des moyens du type ailerons, ou plateformes, pivotants ou escamotables, qui ont pour effet de redresser le navire lorsqu'il est en déplacement dans le sens de son axe de navigation. Dès qu'il n'est plus dans cette situation, les dispositifs en question n'ont plus d'effet sur sa stabilité et le navire peut chavirer si l'action en cause persiste.Known devices of the kind in question use means of the aileron type, or platforms, pivoting or retractable, which have the effect of straightening the ship when it is moving in the direction of its navigation axis. As soon as it is no longer in this situation, the devices in question no longer have an effect on its stability and the vessel may capsize if the action in question persists.
C'est pour remédier à cet inconvénient majeur que le déposant a conçu et testé un dispositif qui a d'une part pour effet de redresser le navire, qui a atteint son seuil de chavirage, et d'autre part de le maintenir dans une position de très grande stabilité en développant dans l'eau un ensemble qui contrebalance l'action persistante en question et qui rend inchavirable le navire concerné. Elle concerne à cet effet un dispositif qui comporte au moins un mât, au moins un hauban et au moins une voilure aptes, une fois déployés en dessous du navire, à le redresser puis à le maintenir dans une position de très grande stabilité.It is to remedy this major drawback that the depositor has designed and tested a device which on the one hand has the effect of straightening the vessel, which has reached its capsizing threshold, and on the other hand of keeping it in a position very stable by developing a set in the water which counteracts the persistent action in question and which makes the vessel concerned unbreakable. To this end, it relates to a device which comprises at least one mast, at least one stay and at least one wing capable, once deployed below the ship, of straightening it and then of maintaining it in a position of very great stability.

Chaque mât comporte au moins un hauban (18,19) reliant chaque extrémité de mât à la partie centrale (20) du navire et sa propre voilure (3), du type filet ou autre, positionnée entre chaque dit mât et le hauban correspondant. Les mâts (1) et (15) sont actionnés indépendamment l'un de l'autre en fonction d'une gîte à bâbord ou à tribord.According to another embodiment of the invention (fig. 4), the device consists, in the case of a catamaran, by 2 masts (1, 15). Parallel and independent, connected, at one end, to distinct articulations (16,17), integral with the ship, placed at the level of each hull (10, 11), perpendicular to the axis thereof. Each mast comprises at least one guy (18,19) connecting each mast end to the central part (20) of the ship and its own wing (3), of the net or other type, positioned between each said mast and the corresponding guy. The masts (1) and (15) are actuated independently of each other as a function of a port or starboard list.
Selon une autre réalisation de l'invention (fig.5), le dispositif est constitué, dans le cas d'un catamaran, par 2 mâts (1,21), parallèles, reliés, à une extrémité, à des articulations distinctes (22,23), solidaires du navire, placées au niveau de chaque coque (10,11), perpendiculairement à l'axe de celui-ci, et par la voilure (3), du type filet ou autre, qui est positionnée entre lesdits deux mâts.According to another embodiment of the invention (fig. 5), the device consists, in the case of a catamaran, by 2 masts (1,21), parallel, connected, at one end, to separate articulations (22 , 23), integral with the ship, placed at the level of each hull (10,11), perpendicular to the axis thereof, and by the wing (3), of the net or other type, which is positioned between said two masts.
