Definitions

  • a boat body or hull especially suitable for racing type sailboats, has a thin outer plastic shell, a plastic inner or false bottom in the shell and secured around its periphery to the shell and a plastic deck covering the shell composed of spaced top and bottom layers; The spaces between the shell and inner bottom and between the top and bottom layers of the deck are filled with a hard foam plastic material itimately bonded by fibrous laminations to the walls defining the spaces with fibers of the laminations embedded in the foam.
  • This invention relates to hollow foam-filled plastic boat hulls and particularly to glass fiber reinforced plastic boat bodies having hard plastic foam-filled chambers with the foam integrally bonded to the plastic walls defining the boat shell, a false bottom for the shell, and top and bottom deck layers, through the intermediary of laminations having fibers embedded in the foam.
  • the spaces between the shell and false bottom and between the top and bottom deck sheets are filled with a-hardened plastic foam and this foam is integrated with the plastic sheets forming the spaces by fiber material bonded to the plastic shell, false bottom and deck sheets and having fibers embed ded in the hard foam filling the spaces between the molded plastic parts.
  • the fibrous material may be woven plastic sheets cemented to the molded plastic parts and may be provided in multiple layers to also act as reinforcements at high stress points in the constructron.
  • the inner lamiations preferably have extending fibers, loops and the like embedded in the foam material.
  • the false bottom provided in the boat body constructions of this invention eliminates the heretofore required necessity for longitudinal and transverse stringers and the false bottom together with the deck provide ample reinforcement for even a very thin boat shell sufficient to resist warping and binding even under severe stress.
  • reinforcements such as a mast foot, a forestay rail, a rudder post, and the like can be provided.
  • Another object of the invention is to provide a lightweight foam filled plastic boat hull with a false bottom effective to rigidify even a very thin boat shell against warpage and bending.
  • Another object of the invention is to provide a sailboat deck and hull construction composed of molded plastic sheets with spaces therebetween filled with hard plastic foam integrally bonded to theplastic sheets.
  • a specific object of the invention is to provide a sailboat body having a fiber reinforced thin molded plastic shell, a false bottom in the shell secured around its periphery to the shell and providing a chamber between the shell and bottom and a deck secured around its periphery to the top of the shell having top and bottom molded plastic sheets with a space therebetween, and hard foam plasticmaterial filling the spaces between the shell and false bottom and between the deck sheets and integrally bonded to the plastic material defining the spaces that are filled by the foam.

  • the boat hull according to the invention the method steps serving for the production of this hull and necessary or suitable devices will be described in detail hereinafter, the construction and assembly of the hull, consisting of the boat shell 101 and the deck 102 being described in detail in connection with FIGS. to la.
  • the boat hull 100 consists of a boat shell 101 and a deck 102.
  • the boat shell 101 has a bow 104 which is shaped approximately in the form of a spoon bow, and an after part 103 of which the stem is formed to slope in forwards and forms a rearward sharp breakaway edge 143.
  • the hull is constructed essentially from a boat shell 101 and an inner bottom 106 arranged in the internal space of the boat shell 101. This inner bottom 106 contains the essential carrying elements of the boat hull and is accordingly provided with a central carrier piece 129, which is hereinafter merely illustrated and described as simple trapezoidal longitudinal profiling.
  • this central carrier piece with single or multiple articulation and possibly profiled to protrude inwards into the boat internal space and/or also downwards into the interspace between inner bottom 106 and boat shell 101.
  • This profiling can continue into the lateral zones 106a of the inner bottom 106 in the longitudinal and/or transverse direction, so that correspondingly according to the invention the essential carrying and shape-maintaining component is constituted by the inner bottom 106, and not as usual by the outer shell 101.
  • a foam material filling 9 which consists essentially of hard foam material and is charged, as will be described later, into the mould cavity between the inner bottom 106 and the boat shell 101, bonding on all sides.
  • the inner bottom 106 is advantageously so arranged that it comes to lie approximately parallel with the floating water line, but slightly above it, the central carrier piece 129 lying approximately in the longitudinal axis of the carrying inner bottom 106 so that it may be regarded as a highly placed keel beam, providing support and formed not as usual on the boat skin 101 but on the inner bottom 106.
  • the central carrier piece 129 lying approximately in the longitudinal axis of the carrying inner bottom 106 so that it may be regarded as a highly placed keel beam, providing support and formed not as usual on the boat skin 101 but on the inner bottom 106.
  • one or more bow reinforcing laminate layers 141, 141a are formed on the boat shell 101 in the region of the bow 104, which reinforce the especially endangered zone of the boat shell 101 in the region of the bow.
  • one or more formed-out portions are provided in the form of a fitting receiving part 132 for the reception of a keel fin 105 in the middle region.
  • This retaining fitting 132 serves to receive a centring piece 133 which is formed on the keel fin 105 in conformity with the retaining fitting 132, the centring piece 133 merging, by way of a transition piece 137 of hydrodynamically favourable shape into the fin surface 134, in the lower region of which a ballast 135 is arranged.
  • the keel fin 105 is separately produced as shell component and is especially moulded in two-shell manner with moulding-in of the ballast 135 in appropriate mould halves, while a reinforcing lamination 136 can be provided in the zone of the keel fin leading edge, and also in the zone of the ballast 135, and furthermore an appropriate transition laminated reinforcement 137 can be provided in the region of the centring piece 133 and also the entire cavity between the shell parts of the keel fin 105 is filled out with hard foam material.
  • keel securing bolts 144 are provided in the upper region of the keel fin or of the centring piece 133, which bolts are introducible approximately parallel upwards into the corresponding retaining fitting 132 of the hull or into the corresponding aperture or receiving part of the middle carrier piece 129 of the inner bottom 106, engage through corresponding bores into the internal space of the hull and are made fast there by eyes, nuts or the like.
  • the keel securing bolts 144 are laminated by means of keel bolt lugs 145 fitted on them to one or the other or both shells of the keel fin 105, corresponding reinforcing laminates or corresponding synthetic plastics material applications being provided in the region of the centring piece 133 of the keel fin.
  • the retaining fitting 132 can be made approximately pyramid-shaped in its cross-section and approximately elliptical in its horizontal cross-section, and can be formedwith its forward retaining fitting 138 and also with its rearward retaining fitting so that a certain keel offset is possible by corresponding approximately spherical or arcuate formation of the individual surfaces.
  • the middle carrier piece 129 of the inner bottom 106 is drawn up in the forward region, that is in the region of the bow 104, approximately in conformity with the curvature of the bow, and is provided in the region of the forestay attachment with a forestay reinforcing laminate 140, which can be made in one or more layers, and a forestay rail 142 can be connected with the forestay reinforcing laminate 140 or 140a.
  • a reinforcing laminate layer 131 is provided in the region of the middle carrier piece 129, which layer can be provided either locally or throughout with further reinforcing laminate layers 131a in the region of the rudder post, in the region of the retaining fitting 132 of the keel fin and especially in the region of the mast foot 139.
  • the actual bottom 130, visible to the crew, of the inner bottom can be lowered more or less in relation to the middle carrier piece 129, especially made oblique in roof form, and extends gradually upwards into the boat shell edge, towards the boat shell 1, at the side parts, as may be seen from FIG. ll.
