Abstract

It is characterised by the elimination of conventional heavy and large keels on single-hull boats and their replacement by underwater resistance ballast plates held in position by a telescopic mast and ropes connected to a winch. Application to all types of boat.

Description

Descriptions de l'invention
Système sous-marin télescopique de stabilisation des bateaux.Descriptions of the invention
Telescopic underwater boat stabilization system.

Doaaaine maritime, tous bateaux.Doaaaine maritime, all boats.

La technique antérieure concernant les quilles classiques de bateaux ou leur fond leurd font apparaître 3 inconvénients majeurs qtui sont:
1 / le poids de ces lests réduit d'autant le rapport d'importance
coque/mâture/voilure.The prior art concerning the classic skittles of boats or their bottom reveals 3 major disadvantages which are:
1 / the weight of these weights reduces the importance ratio accordingly
hull / mast / wing.

2 / le volume immergé coque/quille présente d'autant plus de résistance
à l'avancée qu'il est important.2 / the submerged hull / keel volume has all the more resistance
in advance that it is important.

3 / la stabilité n'est obtenue qu'en fonction du poids du lest et de
la profondeur de la quille.3 / stability is only obtained according to the weight of the ballast and
the depth of the keel.

La tecnique suivante a consisté à essayer de résoudre ces problèmes par le système des multicoques, c'est-à-dire obtention de la stabilisation
par "flotteurs"submarins. Mais l'expérience montre l'extrême fragilité
de tels systèmes et leur cotit prohibitif, par la recherche de la légèreté.The next technique consisted in trying to solve these problems by the multihull system, i.e. obtaining stabilization
by submarine "floats". But experience shows extreme fragility
such systems and their prohibitive cost, by the quest for lightness.

-Mon invention consiste donc à revenir à la coque en bois solide et con
fortable avec mâture en pichepia et à stabiliser ce bateau par deux plaques métalliques, de chaque côté soutenues par des filins treuillés
à plus ou moins grande profondeur et maintenue sous le bateau par une
sorte de mât métallique télecopique sous-marin fixé à l'avant du bateau.-My invention therefore consists in returning to the solid wooden shell and con
fortable with pichepia mast and to stabilize this boat by two metal plates, on each side supported by towed ropes
to a greater or lesser depth and maintained under the boat by a
a sort of underwater telescopic metal mast attached to the front of the boat.

La superficie de ces plaques-lest horizontales est fonction de l'impor
tance du bateau et de la stabilisation que l'on veut obtenir pour permettre telle ou telle voilure.The area of these horizontal ballast plates depends on the size
tance of the boat and the stabilization that one wants to obtain to allow this or that sail.

Ces plaques-lest peuvent être remontées Jusqu'au ni plus haut niveau
afin de permettre au bateau d'évoluer sur les fonds marins les plus petits.These ballast plates can be raised to the highest level
to allow the boat to operate on the smallest seabed.
