  • Figure 17 shows a plan view of the fin system of Figure 13.
  • reference numeral 10 generally designates a water craft, in the form of a surfboard, in accordance with an embodiment of the invention.
  • the surfboard 10 shows three fin systems 12, each in accordance with an embodiment of the invention.
  • Each fin system 12 comprises a fin system component 14.
  • the fin system component or, simply, the component, 14, which is also in accordance with an embodiment of the invention, comprises a carrier in the form of a housing 16.
  • a fin 18 is removably received in the housing 16.
  • the housing 16 defines a mounting formation in the form of a longitudinally extending, outwardly opening channel 20.
  • the channel 20 receives a fin root 22 of the fin 18 therein.
  • the fin root 22 has a bulbous foot 24 received in a wider part of the channel 26 for holding the fin 18 in position relative to the housing 16 and for inhibiting withdrawal of the fin 18 upwardly out of the housing 16.
  • the housing 16 includes a substantially planar mounting surface 28.
  • the mounting surface 28 mounts the housing to an external, lower surface of the surfboard 10.
  • the mounting surface 28 is adhesively secured to the surface 30 of the surfboard 10 via a high strength adhesive.
  • the footprint, i.e. the surface area, of the mounting surface 28 is governed by the adhesive strength required to retain the fin system 12 on the surfboard 10.
  • the fin system 12 includes a locking arrangement 32 ( Figure 6) for locking the fin 18 in position relative to the housing 16.
  • the locking arrangement 32 comprises a plurality of receiving formations, in the form of openings 34 ( Figures 2 and 3), defined in the housing 16. As illustrated more clearly in Figures 5 and 6 of the drawings, these openings 34 extend at an angle through the housing 16 opening into the channel 24. Grub screws 36 of the locking arrangement 32 are received in the openings 34. The grab screws 32 engage the foot 24 of the fin 18 for retaining the fin 18, releasably, in position in the housing 16.
  • the fin 18 has a socket 38 defined in its foot 24.
  • the socket 38 is lined by a liner 40.
  • a fastener such as an Allen-head screw 42 is received in the socket 38.
  • a tip 42.1 of the screw 42 bears against a steel plate 44 in the channel 24 of the housing 16. This causes the foot 24 to rise into contact with a tapering wall 46 ( Figure 5) of the channel 24 to retain the fin 18 in position relative to the housing 16.
  • the fastener could be a fastener of the type having a cam-like lever on its head for displacing a shank relative to the head to facilitate locking retention of the fin 18 relative the housing 40.
  • a rear part 48 of the fin 18 is unsupported by the housing 16.
  • This configuration of fin system 12 is intended to be used by more experienced surfers who require fins 18 which have a rear part that is able to flex.
  • a fin body 50 of the fin 18 is angled with respect to the fin root 52 so that it is not necessary to angle the channel 24 of the housing 16.
  • a variety of differently angled fins 18 can be accommodated in the fin system 12 without the need for any special construction of the surfboard 30 itself.
  • the housing 16 is substantially longer than the length of the fin 18.
  • the fins 18 can be positioned at various different places relative to the housing 16 to cater for surfers of different skills. It will be appreciated that, by varying the position of the fin 18 relative to the surfboard 30, the balance of the surfboard can be altered.
  • leading end 54 of the housing 16 is scalloped to reduce hydrodynamic resistance and cavitation as the surfboard 10 passes through the water.
  • the carrier of the component 14 of the fin system 12 is a substantially planar member 55 defining the mounting surface 28.
  • mounting formation is in the form of a plate 56 standing proud of the carrier on a surface of the carrier 14 opposite of the mounting surface 28.
  • planar member 55 is substantially surfboard shaped.
  • the plate 56 mounts the fin 18 to the surfboard 10 by being received in a slot 58 of the fin 18.
  • the plate 56 has a pair of opposed receiving formations, each in the form of a longitudinally extending groove 60, defined in it. Grub screws 62 are received through openings in the fin 18 and engage their associated grooves 60 for retaining the fin 18 in position on the carrier 14.
  • the slot 58 is longer than the plate 56 to facilitate longitudinal adjustment of the position of the fin 18 relative to the surfboard 10.
  • the plate 56 can project at right angles to the carrier 14. Instead, to provide angled fins, the plate 56 may project at a corresponding angle relative to the upper surface of the carrier 16.
  • the fin 18 has a fin body 64 and an enlarged foot portion 66 integrally formed with the fin body 64 as a one piece unit.
  • the foot portion 16 flares outwardly from the fin body 64 and defines a mounting surface 68 for mounting the fin body 64 to the external, lower surface of the surfboard 30.
  • the fin body 64 projects at right angles to the foot portion 66 or, instead, projects at an angle as shown in dotted lines in Figure 14 of the drawings.
  • a fin system is provided which does not require holes to be made in the body of the surfboard 30. This ensures that the structural integrity of the surfboard is maintained. In addition, it is easy to adjust the position of the fins relative to the surfboard using the fin system. Thus, the same surfboard can be used by surfers of differing skills.
  • angled fins can be mounted on the surfboard and can cater for variations in the shape of lower surface of the surfboard.
  • the housing 16 of the fin component 14 is simply adhered to the body of the surfboard after moulding of the body of the surfboard and it is not necessary for the housing 16 to be moulded into the body of the surfboard.
  • the contact area of the enlarged foot portion 66 with the surfboard 30 provides the necessary strength to retain the fin 64 on the surfboard.
  • the housing does not intrude into the body of the surfboard and reduces localised stress points in the surfboard.
