Definitions

  • the subject of the invention relates to an ultra thin boat body which contains a hull with a nose part, middle part and rear part, and hydrofoil elements connected to the hull by means of a connection unit in such a way so that they can move.
  • the ultra thin boat body with improved sailing features according to the invention which contains a hull with a nose part, middle part and rear part, and hydrofoil elements connected to the hull by means of a connection unit in such a way so that they can move, is constructed in such a way that the connection unit has a torsion spring unit, and the hydrofoil element, with the interposition of the torsion spring unit, is fixed to the hull.
  • Another criterion of the boat body according to the invention is that the hydrofoil elements are positioned on the two longitudinal sides of the hull.
  • the hydrofoil element has a fixing zone that can be connected to the connection unit, and there is a front hydrofoil part positioned before the fixing zone and a rear hydrofoil part behind the fixing zone.
  • the operating surface of the front hydrofoil part and the operating surface of the rear hydrofoil part are of different sizes.
  • connection unit has an adjustment partial unit connected to the torsion spring unit.
  • connection unit has a seating unit and in the seating unit it has one or more catches, the torsion spring unit is formed by deforming, force- absorbing rubber blocks that are parallel along their longitudinal axis, a part of the deforming, force-absorbing rubber blocks is fitted between the catches, and the hydrofoil unit is held between the deforming, force-absorbing blocks.
  • connection unit has a seating unit and in the seating unit there are one or more catches, the torsion spring unit is formed by coil springs, one end of the coil spring is fixed to the connection unit and the other end is fixed to the fixing zone of the hydrofoil.
  • connection unit has a seating unit and one or more catches are positioned in the seating unit, the torsion spring unit is formed by one or more spiral springs, one end of the spiral spring is connected to the connection unit and the other end is fixed to the fixing zone of the hydrofoil.
  • the boat body according to the invention has numerous advantageous features. The most important of these is that due to the unique combination of the long, thin, arrow-like hull and the hydrofoil units a boat body can be formed that has a continuously, automatically changing, speed-dependent draught, which, as a consequence of its ultra thin construction, and due to the low drag, is fast, is not liable to overturn, and still very manoeuvrable with a good attitude.
  • the deck level of the boat body is, when the boat is stationary, close to the water surface, however, when the boat is travelling at its normal speed the deck level rises high above the water.
  • the boat body can be used especially effectively as a rescue boat, as in a stationary, i.e. rescuing position its stable deck close to the water makes getting people out of the water easier, as it rises high out of the water while travelling quickly the waves do not easily break onto the deck of the boat body, even in the case that the gunwales are not too high.
  • a further advantage is that the pre-tensioning of the hydrofoil elements, or the spring force resistance characte ⁇ stics can be changed if necessary, so the sailing features of the boat body - within certain limits - can be changed in accordance with the characte ⁇ stics of the water being sailed on and the sailing circumstances
  • Still another advantage is that as a consequence of the better sailing features, but mainly the significantly reduced drag and the better manoeuvrability, the boat body fitted with a low output engine gives performance like that of traditional boat bodies fitted with larger engines, so the specific operation cost of boats fitted with the boat body according to the invention is significantly lower

  • the hull 20 is constructed of a nose part 21, a middle part 22 and a rear part 23 and made of generally applied materials, e.g. fibre reinforced resin, just like hull 30 and the connection member 11.
  • the length and width of the hull 20 can vary between wide limits depending on the water sailed on, so a hull 20 destined for freshwater could have a width of 10-15 cm and a length of 2.5-4 m, a sea-going hull 20 could have a width of 10-25 cm and a length of 4-12 m, while an ocean-going hull could have a width of 20-60 cm and a length of 10-27 m.
  • the depth of the position of the hydrofoil elements 50 and so the connection units 40 on the hull 20 also differs between 0.4-3.8 m.
  • the selection of favourable proportions takes place in consideration of the purpose and other features.
  • the hull 20 - and also the hull 30 - is fitted with hydrofoil elements 50.
  • Two hydrofoil elements 50 are placed on the external longitudinal side 24 of the hull and two are placed in the internal longitudinal side 25 symmetrically to the main plane 26 in such a way that the first two hydrofoil elements 50 are fitted to the nose part 21 of the hull 20, while the rear two hydrofoil elements 50 are fitted to the rear part 23 of the hull 20.
  • the hydrofoil elements 50 on the external longitudinal side 24 of the nose part 21 and on the internal longitudinal side 25 of the nose part 21 are fitted to a common axle 54, which axle 54 is fitted into the connection unit 40 fixed to the nose part 21 in such a way so that it may rotate.
  • the hydrofoil element 50 consists of a front hydrofoil member 51, a rear hydrofoil member 53 and a fixing zone 52 situated between them, and the axle 54 is connected to the fixing zone 52.
  • the operating surface 51a of the front hydrofoil part 51 of the hydrofoil part 50 is smaller than the operating surface 53a of the rear hydrofoil part 53.
  • This surface different is a question of dimensioning, and its extent depends on the size of the boat, its planned running speed and the characteristics of the water on which the boat is navigated, so the construction of the hydrofoil elements 50 and the shape of the front hydrofoil part 51 and the rear hydrofoil part 53 is different in the case of the hydrofoil element 50 of a boat body 10 for sea navigation and in the case of the hydrofoil element 50 of a boat body 10 for river or lake navigation.
  • connection unit 40 shown in figure 1 has a seating unit 42 in which there is a torsion spring unit 41, which, in the case of this construction, is formed by four rubber blocks 44.

  • catches 43 which are plates butting into the seating unit 42 from the connection unit 40.
  • the rubber blocks 44 serving as torsion spring unit 41 is placed beside these catches 43, so that at the same time they surround the fixing zone 52 of the hydrofoil element 50.
  • the seating unit 42 of the connection unit 40, the catches 43 and the rubber blocks 44 are constructed in a way that there is exactly enough space for the fixing zone 52 of the hydrofoil element 50 and the axle 54 to fit in the area between the rubber blocks 44, that is in the normal position of the hydrofoil element 50 the torsion spring unit 41 does not exert any deviating force on the hydrofoil element 50.
  • the hull 20 and the hull 30 of the boat body 10 go into the water in the same way, and the hydrofoil units - as is shown in figure 1 - are positioned turned off the horizontal so the front hydrofoil part 51 is above the horizontal and the rear hydrofoil part 53 is under the horizontal. With the hydrofoil unit in this state the operating surface 51a and the operating surface 53a look slightly towards the front.

  • the task of the adjustment partial unit 46 is to give the coil sp ⁇ ng 47 that forms the torsion sp ⁇ ng unit 41 the necessary pre-tensionmg in accordance with the characte ⁇ stics of the water being sailed on
  • the hydrofoil unit 50 is in a position turned off the ho ⁇ zontal, and also that the operating surface 51a of the front hydrofoil part 51 in this case is smaller than the operating surface 53a of the rear hydrofoil part 53

  • the hull 20 can not only be used in catamaran-type boat bodies 10, a version may be imagined where the boat body 10 consists of a single hull 20. In the case in order to retain stability the hull 20 needs to be given the necessary keel
