Definitions

  • This invention is for a new mooring procedure specially desired for sports craft, and in particular for boats which must be moored over long periods of time for most of the year.
  • the invention also includes the device used to put this procedure into practice, and it is thanks to this that the craft's stern is raised high enough with respect to the surface of the water to keep the motors, tailpieces, propeller shafts and other metal parts clear of the water, thus preventing corrosion from salt water and the subsequent repercussions on the service life of such equipment.
  • the mooring procedure proposed by this invention solves these problems, and allows the boat to remain securely moored in the water for as long a period as is required without exposure to the above-mentioned damages caused by corrosion.
  • This procedure consists of raising the stem by placing an inflatable component below it attached to the boat itself so that all metal components which could be damaged by corrosion are kept clear of the water. These may also be greased down, and covered with plastic sheeting or tarpaulins to provide then, with suitable protection for the entire period during which the boat is not in use.
  • Two inflatable floats are used to put this procedure into practice. They are connected to each other in accordance with the width of the boat, preferably with a pneumatic connection so that their respective pressures are automatically kept the same and to prevent asymmetric buoyancy effects.
  • the floats have a rigid upper base to make contact with the hull, so that the connection between the floats is between both rigid bases.
  • the means of connection may be two warps zigzagging between perforated brackets on the rigid bases, which shall also include further external brackets to attach the floats, also by means of warps, to suitable mooring points on the sides of the craft. All these warps shall have suitable tightening devices to secure the device to the hull of the craft.
  • the rigid bases shall be grooved so that when the float is inflated it creates "stud" deformations which slide into the grooves and establish direct contact with the hull for better adhesion and to prevent damage to the float.
  • the floats shall also be slightly conical, and shall converge forwards so that maximum buoyancy is to the rear for optimum buoyancy torque without destabilising the craft, but tending to raise the stem and therefore keeping the above-mentioned metal components clear of the water.
  • this device may be used as an auxiliary catamaran by connecting the two floats with rigid beams,
  • the catamaran may also be independently operated either manually or using a small outboard motor.
  • Figure 4 shows how, in accordance with procedure for the invention, the boat (1) is forced to tilt lengthwise, raising its stem (2) so that the motor (3) and other metal components at the far end to the rear are lifted clear of the water.
  • a device is used to this end which consists of a pair of floats (4-4'), sized in accordance with the dimensions of the boat (1) for suitable upward buoyancy.
  • These two floats (4-4') are pneumatically linked by a connection pipe (5), which ensures completely uniform pressure for each of them and, if required, also allows the floats to be inflated using only the inflating valve (6) on one of them.
  • the floats (4-4') are also mechanically interconnected by, for example, two warps (7) with end tighteners (8) zigzagging between fastenings (9-9') connected to the respective floats (4-4') by, for example, the perforated brackets clearly visible in figures 1, 2 and 3.
  • perforated brackets (9-9') shall be located over the facing edges of the floats (4-4'), and they shall be quite coplanar or horizontal to secure the warps (7).
  • Each float (4-4') shall have another external perforated bracket (10-10') similar to the above, although bent upwards. Its orifices shall be used to secure the warps (11) which attach the entire device to the craft (1), as shown most clearly in figure 4.
  • brackets (9-10) and (9'-10') shall form part of two rigid components (12-12') which comprise the float's upper base and more specifically the area of contact between both floats and the hull of the craft (1). This prevents unwanted friction which could damage the floats, and also isolated stress on the warp fastenings which could also damage the floats if it were concentrated on their walls.
  • the rigid components (12-12') have a number of crosswise grooves (13) so that, while the floats (4-4') are being inflated, "studs" are created for a tongue-and-groove attachment, thus increasing the unit's stability.
  • the device is attached to the base of the craft at the end of the stem, with the floats (4-4') deflated to make the operation easier to carry out, A suitable space must first be left between the floats by adjusting the tighteners (8) controlling the working length of the interconnecting warps (7).
  • the floats (4-4') are inflated, the boat (1) raises its stern (2) and lifts the tailpieces, the propeller shaft, the motor and other metal parts clear of the water.
  • the floats (4-4') carry out two functions in that when the boat is in use and they are not required, they may be locked together by means of rigid spacers not shown in the figures and lock on to brackets (9) and (10) to form a small kind of auxiliary catamaran.
  • the floats (4-4') shall have a section decreasing towards the front, as may be observed most clearly in figures 1 and 2. This craft may be rowed or driven by a small outboard motor.
