Definitions

  • the present invention relates to a pleasure craft, which may be sail or motor, designed for navigation on the one hand and on the other hand the observation of the seabed.
  • the present invention intends to propose a boat which allows on the one hand to navigate like a normal boat, and this for several days taking into account the interior equipment that this boat can contain, and on the other hand either immobilize it, or reduce its speed to obtain a marine environment observation post.
  • the invention therefore makes it possible to combine the pleasures of navigation as pleasure and leisure boats for all cruises and the pleasures of observing the place where the flora and fauna are particularly developed. It can also constitute, for specific uses, a location or surveillance bubble for, for example, diving schools.
  • the invention therefore relates to a pleasure craft comprising a hull with a flat bottom.
  • this boat comprises a well substantially in the center of the bottom of the hull, in which is slidably mounted a cylindrical element comprising in its side wall at least one porthole, closed at its lower end, and a device for operating the cylindrical element in the well, between a first position in which the outer wall of said closed end is substantially at the bottom of the hull, and a second position in which said end is moved away from said bottom, by a distance allowing said porthole to be located under the hull.
  • the operating device is constituted by a screw-nut device, the screw of which is integral with a structural element of the shell and is coupled to a geared motor for rotation while the nut is integral with the cylindrical element.
  • the cylindrical element will advantageously include a ballast in its lower part, so that its rest position is substantially halfway between the two abovementioned end positions.
  • section of the cylindrical element will advantageously be elliptical, the major axis of this ellipse being oriented in the direction of advancement of the boat.
  • the boat which is here provided motorized, has a hull 1 whose bottom 2 is flat and provided with a ballast.
  • the hull comprises a cabin 8 covered with a roof 9.
  • the cabin is mainly divided into two spaces, a first lateral and rear space 10 in which one will find utility equipment such as hot plates or a sink and toilet, and a central space 11, separated from space 10 by a partition vertical 12 which constitutes the at least partial extension of a well 13 formed in the bottom 2 of the shell 1.
  • a cylindrical element 14 is slidably mounted in the well 13 and guided in its sliding by means of guides 15 cooperating with rollers 16 integral with the upper periphery of the cylindrical element 14.
  • This cylindrical element 14 which will be called a nacelle later, has a closed bottom 14a in which ballast compartments 17 are provided. These compartments 17 are located at the periphery of the bottom 14a so as to constitute benches around the interior space of element 14. It will be noted in the figures that the section of this cylindrical element 14 is elliptical with its major axis oriented along the axis of the boat. It can be seen that the side wall 18 of the nacelle 14 is equipped with four portholes 19 which, when the nacelle projects from the hull 1, are located under this hull and allow the observation of marine environments located under the boat, as shown in the left part of FIG. 2.
  • This left part also illustrates one of the extreme positions that the nacelle can take relative to the hull 1, the right part of FIG. 2 illustrating the other extreme positions of the nacelle relative to the hull, in which the bottom 14a is appreciably in the plane of the bottom 2 of the hull.
  • a mechanism for maneuvering the nacelle between these two positions is constituted by a screw-nut device comprising a screw 30 coupled to the roof 9 of the cabin and capable of turning in a fixed bearing, driven by a geared motor group 31.
  • the basket 14 includes as for a central column 32 which carries a fixed nut cooperating with the screw at its upper part, not shown, which, when the screw 30 rotates, moves in translation along the latter and causes the nacelle to go up or down.
  • the screw is preferably housed in a fixed sleeve 33 in which the upper end of the hollow column 32 provided with the nut can evolve. The screw is therefore never discovered.
  • this operating device consists of a stirrup 20 which has two branches 20a and 20b and an axis 21.
  • the branches 20a and 20b are integral with the axis 21 which can rotate in bearings 22 belonging to the structure of the boat.
  • the stirrup 20 can pivot in the bearings 22.
  • Each arm 20a and 20b has an extreme longitudinal lumen in which an axis 24 carried transversely and externally by the nacelle 14, can slide.
  • ballast is such that the rest position of the nacelle corresponds to an intermediate position between the high and low positions illustrated by Figure 2, that is to say for a substantially horizontal stirrup position.
  • This arrangement makes it possible to use a jack 23 of lesser power than if there was no ballast.
  • Each of the extreme positions of the nacelle is, because of this ballast, obtained by positive action of the jack.
  • the interior space of the nacelle is here equipped with a table 25, occupying the center of the bottom 14a and surrounded by the bench arranged above the ballast compartments 17. It will be noted that the table 25 is mounted on a telescopic column 26 .
  • a notch 12a of the wall 12 which can be crossed at from the space 10 of the cabin 8 by means of a ladder 27, while a ladder makes it possible, from this notch, to reach the bottom of the nacelle.
  • a boat such as that shown may have a length of 6,700 mm, a width of 2,500 mm, a retracted basket height of approximately 2 m, the basket being able to dive 1 m below the bottom of shell.
  • a boat can easily be transported by road like traditional boats.
  • the interior space of the nacelle can be arranged to constitute a dining room during the day, and at night a sleeping space that can accommodate up to three people.
  • the invention finds an interesting application in the field of pleasure boating.
  • each porthole 19 of a projector 28 which can be rotated from inside the cabin, manually, in order to illuminate a particular underwater area.
