Definitions

  • the invention relates to a Bowsprit arrangement of a bowsprit and a bracket which is attachable to a sailboat whose mast is held with a forestay and shrouds.
  • the invention has for its object to provide a bowsprit arrangement that is easy to handle and that can not be used only in the setting of gennakers.
  • the holder forms an attachable before the forestay at the bow of a sailboat assembly containing a receptacle for the bowsprit, which is pivotable about a horizontal or vertical first axis, wherein the bowsprit in the receptacle about a second axis is held pivotally, which runs perpendicular to the first axis.
  • the bowsprit By pivoting about the horizontal axis, the bowsprit is preferably pivoted up into a position parallel to a forestay, so that it does not interfere with the maneuvering of the boat.
  • the front anchor point of the gennaker or other foresail can be moved from the center to windward or leeward, which can be especially beneficial for sailing under gennaker.
  • the bowsprit can be used not only when sailing under gennaker, but especially when sailing under spinnaker, in which case the bowsprit serves as a substitute for a spinnaker pole.
  • the bowsprit which can be swiveled through at least 180 °, ie 90 ° to port and 90 ° to starboard, makes spinnaker sailing much easier. While the movement of a spinnaker pole moored to the mast is limited by the forestay, there is no such limitation on the bowsprit. The spinnaker or other headsail can therefore be moved further on the leeward side than is possible with a spinnaker pole or a solid forestay. In addition, the spinning of the spinnaker is much easier because it eliminates the need for using a spinnaker pole implementation. If a spinnaker is used, with which between both horns one Guide line is provided for the attached to the bowsprit fitting, so a schiften can be performed without a person on the foredeck and work there must perform.
  • FIG. 1 only schematically illustrated sailboat 10 has a mast 11 which is braced with a forestay 12 and shrouds 13, which are guided over Salings 14. On the mast the luff of a mainsail 15 is performed, the underbelly is guided in a boom 16.
  • a spinnaker 17 For courses in front of the wind, it is advisable to place a spinnaker 17.
  • the spinnaker neck is pulled in a manner not shown by means of a Spinnaker case on the mast.
  • the two horns 18, 19 of the spinnaker are held by means of pods 20, 21 which are led aft to the cockpit of the boat 10.
  • the Luvhorn 19 of Spinnaker 17 is being flattened. This expansion takes place by means of a bowsprit 22, which is pivotable by means of a bracket at the bow of the sailboat 10 by an angle of at least 180 ° about a vertical axis, as will be explained in more detail later.
  • the bowsprit 22 serving as a replacement for a spinnaker pole can be pivoted beyond the longitudinal center of the sailboat 10 to to adapt the Spinnaker 17 'better to a space wind course.
  • the mainsail hardly covers the spinnaker on most courses, because it is further ahead of the usual arrangement of a spinnaker with a spinnaker boom held on the mast.
  • This pivoting of the bowsprit 22 about a substantially vertical axis can take place by means of an electric or pneumatic or hydraulic drive.
  • means may be provided for pivoting, as they are known for Rollfock facilities.
  • bracket 23 shown in detail consists of a base part 25 which is attached to the bow 26 of a sailboat.
  • a receptacle 27 is rotatably mounted about a substantially vertical axis 28.
  • the receptacle 27 receives the pivotable about a horizontal axis 29 bowsprit 22.
  • the receptacle 27 forms a stop 30, which limits the movement of the bowsprit 22 downwards such that the bowsprit 22 is oriented at least approximately horizontally in the lowermost position. That can go upstairs Bowsprit 22 are pivoted about the horizontal axis 29 so far that it runs approximately parallel to the forestay 12, which is formed in the embodiment as a furling jib.
  • the receptacle 27 is provided with a lying below the base member 25, with rotating about the vertical axis 28 approach 31, which forms a lying in the longitudinal direction of the boat in front of the horizontal axis 29 pivot point 32 for a gas spring 33.
  • the gas spring 33 is articulated to the bowsprit 22 and exerts on the bowsprit 22 a force that wants to pivot the bowsprit 22 upwards.
  • the bowsprit 22 is pivoted downwardly and held in the downwardly pivoted position by means of a downer 34, which consists of a hinged to a fitting 35 of the bowsprit 22 rope running around pulleys 36, 37 and guided backwards into the cockpit of the boat is.
  • the gas spring 33 causes the bowsprit 22 to pivot upwardly to a position substantially parallel to the forestay 12 defined by a preferably adjustable stop.
  • the fitting 35 has a second point of articulation on which a case 38 or a forestay of a gennaker can be struck.
  • the articulation point for a case 38 or a topnant or a forestay is preferably adjustable in its distance from the receptacle 27.
  • the bowsprit 22 may be provided with a perforated rail or on the upper side with a longitudinal groove in which a fitting can be moved and fixed.
  • the bowsprit 22 is designed as a two-part telescopic rod, the second part of which can be extended outwards beyond the fitting 35. This extendable and lockable in extended position part is provided at its end with a Spinnakerbeschlag 39.
  • the pivoting of the receptacle about the vertical axis 28 can be effected by cables, either on the bowsprit 22 or in the manner of a Rolling roller rolling device attached to the receptacle 27.
  • electric drives, pneumatic drives or hydraulic drives can also be readily provided for pivoting, which can be arranged below the receptacle 27, in particular in the region of a basket 40.
  • the holder 23 is arranged so that the receptacle 27 for the bowsprit 22 lies in front of the bow 26 of the boat.
  • this arrangement is required only when the forestay 12 is located at the top of the bow 26.
  • a modified bracket 23 may be provided, which is arranged so that the receptacle 27 is still placed in front of the forestay 12, but not in front of the bow.
  • the holder includes a receptacle which is pivotable about a horizontal axis in which the bowsprit is pivotable about a vertical axis.
