Definitions

  • the present invention relates to an hull construction for a class of small sporting boats.
  • This class of small watercrafts is designed to be ridden by a single rider seated astride on the seat bench at the longitudinal center of the watercraft and to carry possibly one,two, three or four passengers, also seated astride on the seat bench behind the rider.
  • the new invention relates to un hull able to make this kind of watercrafts usable as boats to give rescue.
  • This new hull consruction is also able to increase the speed when travelling straihgt ahead and to improve stability and manoeuvrability under a wide variety of steering, particulary in turning.It introduces the change to join a deck with a bow platform carrying an anchor upper cavity on one side, a central upper cavity for battery inspection, a third upper box-objects cavity on the other side, each one complete with door, a refrigerator cavity under the seat, and two spaces on both sides of the rider usable as lodging platforms for two rescue stretchers, to a bottom hull realized such like a trimaran bottom hull, which allows speed but also stability and manoeuvrability when turning.
  • the large sized engine and the proplusion unit are positioned to the lower stem, beneath the watercraft rised seat.
  • variations in the number of the passengers can determine a different cargo conditions towards the stem.
  • passengers usually board the jet boat from the water (to such aim is frequently provided a stem deck). So inclinations due to the posterior weight, which widely condition the ddesign of the hull, may happen.
  • the main object of the new invention is to provide an hull design which guarantees the floatation and control of the boat, indipendently from the number of passengers, keeping the compartment of the passengers, relatively small and compact, making so the deck to carry the upper cavities and two spaces usable to give rescue (lodging platforms for two rescue stretchers).
  • Further object of the invention is to allow the realization of an economic and ecological jet boat, providing, by the configuration of the bottom hull, (consisting of three parallel bodies tight and lengthen), the housing of a small low power engine of low consumption (because of the smaller bathed surface of the hull compared with the analogous boats of famous type, and therefore of the smaller friction with the water).
  • pict. 1 shows a top plan view and the dimensional outline of the hull of a preferred embodiment according to the new invention
  • hull (1) realized such like a trimaran bottom hull, consisting of a main body (3) and two lataeral bodies (4), parallel to the main body, each one having a V bottom(triangular cross sectional shape).
  • the V bottom includes two angulary disposed surfaces (5) extending outside of the keel and ending, in the external bodies (4) of the bottom hull, with horizontal chines (6) lightly extending outside of the keel, parallel to the keel longitudinally.
  • the chines are normally out of the water when the boat travels straight ahead or at the plan down speed, while during the turning (when the rider shifts his weight from side to side of the watercraft), the watercraft is tilted on the angulary disposed surfaces (5) and the chines (6) are in contact with the water as illustrated in pict.6.
  • This kind of bottom hull allows stability and manoeuvrability in turning, and exceptinal speed to equal power, compared with the anologous well known boats because of the smaller friction of the bottom hull with the water.
  • each body of the hull realized such like a trimaran bottom hull, riduces te resistance met during straighting ahead because of the smaller surface brought into contact with the water (and then because of the smaller friction with the water), while the angulary disposed surfaces by the sides of the keel are adapted to became submerged in the body of the water both in the turning and in the departure for improving the stability and resisting any further rolling of the watercraft.
  • the watercraft is travelling straight ahead at high speed, only the angular surfaces by the sides of the keel, are completely in contact with the water, while the chines are in contact with the water only along their lower surfaces.
  • the bow platform allows to accomodate an anchor uper cavity (19), a central upper cavity for battery inspection (18), and a third upper box objects cavity (19) each one complete with door,while on the deck spaces on both sides of the rider (16) two rescue stretchers (17) are assembled on suitable sledges.
  • the stretchers may be untrheaded and used at once in the water, and then taken out of the water by hand or by means of little optional electrical winches controlled by watertight push bottons mounted on the stem of the hull. Moreover to move the patients, the stretchers may be unhooked in a mechanical way. Furthermore the blow platform has some handles (14), to facilitate the boarding of the jet boat, extending on both sides of the platform for all its lenght,adapted to be seized from people staying into the water, allowing them to exercise a pressure and to board the jet boat.
