Abstract

Device for modifying the compression and outlet of water at the rear of boat bottoms. The invention relates to a device making it possible to improve the compression and outlet of water at the rear (stern) of boat bottoms (underwater hulls) as well as the stability of the floats. It is made up of a double vee (1) executed under the boat bottom (4), the internal (2) and external (3) opening of which can vary depending on the appliance; it has two rails (5) under the boat bottom at the junction of the vees (2-3). The device according to the invention is particularly intended for the floats of sailboards, surfboards, and for some boats.

Description

La présente invention concerne un dispositif adaptable aux carenes qui évite la compression d'eau et améliore la sortie cohérente de celle ci à l'arrière des flotteurs. The present invention relates to a device adaptable to the hulls which avoids the compression of water and improves the coherent output of the latter at the rear of the floats.

La vitesse élevée des flotteurs actuels crée sous la caren des problèmes de compression d'eau ainsi que d'évacuation. Les dispositifs connus et appliqués le concave et la plat-vé crée turbulences pour l'un compression pour l'autre. The high speed of the current floats creates under the hull problems of water compression as well as evacuation. Known and applied devices, the concave and the flat-vee, create turbulence for one compression for the other.

Le dispositif selon l'invention permet de remédier à ces inconvénients. Il se compose suivant sa caractéristique d'un double vé (1) qui est formé d'un vé intérieur (2) d'un vé extérieur (3). The device according to the invention overcomes these drawbacks. It is composed according to its characteristic of a double vee (1) which is formed of an inner vee (2) of an outer vee (3).

L'ouverture du vé intérieur (2) et du vé extérieur (3) est adaptable suivant le modèle de carene le double vé (1) s'exécute en progression sur la carene à partir du maître-bau (4) et se termine à l'arrière du flotteur. The opening of the inner vee (2) and the outer vee (3) is adaptable depending on the hull model. the back of the float.

En trajectoire le vé intérieur (2) permet la sortie rapide de l'eau il soulage l'aileron par appui sur l'eau dans les manoeuvres à haute vitesse Fig.4. In trajectory the internal vee (2) allows the rapid exit of the water it relieves the fin by pressing on the water in high speed maneuvers Fig. 4.

Le dispositif à la jonction des vés permet d'obtenir sous la carene deux rails (5) qui permettent de stabiliser le flotteur favorisent le déjaugement et son contrôle. The device at the junction of the ves makes it possible to obtain under the hull two rails (5) which make it possible to stabilize the float promote planing and its control.

A titre d'exemple non limitatif le vé intérieur (2) aura 3mm d'ouverture le vé extérieur (3) 5mm quant à la largeur on l'adapte suivant l'appareil. By way of nonlimiting example, the inner vee (2) will have 3mm of opening the outer vee (3) 5mm as to the width, it is adapted according to the device.

Le dispositif selon l'invention est particulièrement destiné au flotteurs de planche à voile, au surf et à certains bateaux.  The device according to the invention is particularly intended for windsurfing floats, surfing and certain boats.
