Definitions

  • the present invention relates to a sailboat, and more particularly, to a sailboat with left and right jibs.
  • sailboats may be distinguished by the number of masts being established and thus can be divided into two categories, i.e. single-masted sailboats and multi-masted sailboats. It is noted that the multi-masted sailboats include double-masted sailboats and three-masted sailboats, but are not limited thereby. Moreover, traditional sailboats are monohulls, but multi-hull catamarans and trimarans are gaining popularity.
  • a monohull sailboat has only one mast, it is a single-masted monohull sailboat; and if there is more than one mast on a sailboat, it can be a multi-masted monohull sailboat.
  • the sailboat is a single-masted sailboat, but it is not limited thereby.
  • FIG. 1A is a schematic diagram showing a conventional single-masted monohull sailboat. As shown in FIG.

  • the first jib 76 and the second jib 77 will not be used simultaneously unless the sailboat 7 is sailing with a tailwind, but are used alternatively and selectively according to the direction of wind. That is, when the air heading is blowing toward the sailboat 7 from its starboard side 707, the first jib 76 is expanded and used. Otherwise, when the air heading is blowing toward the sailboat 7 from its port side 706, the second jib 77 is expanded and used.
  • the second jib 77 can be rolled up and furled by the rig connecting the first end 770 and the second end 771 of the second jib 77 for pulling and receiving the third end 772 of the second jib 77 to a position between the first and the second ends 770, 771.
  • the first jib 76 should be furled and rolled up similarly while rigging the third end 772 of the second jib 77 to the second winch 75 by way of the second pulley 750.
  • the boom 78 is configured with a first end 780 and a second end 781 at positions opposite to each other while enabling the first end 780 to be coupled with the mast 71; and the mainsail 79 is configured with a plurality of ends including a first end 790, a second end 791 and a third end 792 in a manner that the first end 791 of the mainsail 79 is coupled to the second end 711 of the mast 71, the second end 791 of the mainsail 79 is coupled to the first end 780 of the boom 78, and the third end 792 of the mainsail 79 is coupled to the second end 781 of the boom 78.
  • FIG. 5C is a schematic diagram showing a double-masted catamaran with fully extended left jib according to the present invention.
  • FIG. 5C is a schematic diagram showing a double-masted catamaran with fully extended left jib according to the present invention.
  • each of the mast in FIG. 5C can be rigged with a boom and a mainsail so that it is not limited thereby.
  • the multi-hull sailboat of the present invention is different from those conventional multi-hull sailboat in that:
  • FIG. 5E and FIG. 6D are schematic diagrams illustrating a zigzagging sailing trajectories of the single-masted catamarans of FIG. 5A and FIG. 6A .
  • the two single-masted catamarans are sailing from a point of departure 80 to a destination 81 following different zigzagging trajectories. Comparing the sailing trajectories shown in FIG. 2C , FIG. 5E and FIG.6D , it is noted that the voyage distance of the multi-hull sailboat disclosed in the present invention is shorter than that of a conventional multi-hull sailboat.
  • FIG. 7A is a top view of a single-masted monohull sailboat with its two jibs fully extended according to the present invention. It is noted that although the sailboat in FIG. 7A is a single-masted sailboat, the amount of masts is not limited thereby. While sailing with a tail wind as the wind direction 010 indicated in FIG.
  • the monohull sailboat 5 can simply release the third end 562 of its first jib 56 that is rigged to the first winch 54 and also release the third end 572 of its second jib 57 that is rigged to the second winch 55 for enabling the two jibs 56, 57 to expand and thus to be used as spinnakers.
  • the single-masted monohull sailboat is configured with a mainsail, it is not limited thereby, i.e. any sailboats of the invention without mainsail still can use its jibs as spinnaker by expanding the same in the aforementioned way.
  • the spinnaker 9 is rigged to the top of the mast and any two points on the left and right to the center line of the hull module, and thereby, since the monohull sailboat of the invention is configured with two fixing elements respectively on the port side and the starboard side of the hull module and two winches as well, the rigging of the spinnaker on monohull sailboat of the invention is much easier than that on any conventional sailboat.
  • the monohull sailboat in FIG. 7B is a single-masted monohull sailboat, the amount of masts is not limited thereby. As shown in FIG.
  • the spinnaker 9 is configured with a plurality of ends including a first end 90, a second end 91 and a third end 92. While sailing with a tail wind as the wind direction 010 indicated in FIG. 7B for example, the first end 90 of the spinnaker 9 is coupled to the mast, the second end 91 of the spinnaker 9 is rigged to the first winch 54 and the third end 92 of the spinnaker 9 is rigged to the second winch 55. On the other hand, in addition to the aforesaid connection, the second end 91 and the third end can be connected directly to the first and the second winches 54, 55. Moreover, the expanding of the left and right jibs can be enabled simultaneously with the use of spinnaker, by that the sailboat can be propelled by more wind and thus the sailing speed is increased.
  • FIG. 8A is a top view of a single-masted multi-hull sailboat with its two jibs are fully extended according to the present invention.
  • the multi-hull sailboat in FIG. 8A is a single-masted multi-hull sailboat, the amount of mast is not limited thereby.
  • the catamaran 7 can simply release the third end 762 of its first jib 76 that is rigged to the first winch 74 and also release the third end 772 of its second jib 77 that is rigged to the second winch 75 for enabling the two jibs 76, 77 to expand and thus to be used as spinnakers.
  • the single-masted catamaran is configured with a mainsail, it is not limited thereby, i.e. any multi-hull sailboats of the invention without mainsail still can use its jibs as spinnaker by expanding the same in the aforementioned way. Nevertheless, the spinnaker 9 can also be used on a multi-hull sailboat of the invention, as shown in FIG. 8B .
  • the catamaran shown in FIG. 8B is a single-masted catamaran, the amount of masts is not limited thereby.
  • the spinnaker 9 is configured with a plurality of ends including a first end 90, a second end 91 and a third end 92.
  • the first end 90 of the spinnaker 9 is coupled to the second end 711 of the mast 71 by way of the first winch 74, the second end 91 of the spinnaker 9 is rigged to the first winch 74 and the third end 92 of the spinnaker 9 is rigged to the second winch 75.
  • the second end 91 and the third end can be connected directly to the first and the second winches 74, 75.
  • the expanding of the left and right jibs can be enabled simultaneously with the use of spinnaker, by that the sailboat can be propelled by more wind and thus the sailing speed is increased.
  • the sailboat of the invention is designed to meet with user's demands by enabling the left and right jibs of the sailboat to operate in an alternating manner so as to enable the sailboat to be operable without the mainsail and boom, and thus not only the construction cost relating to the mainsail and boom can be save, but also the operation procedure as well as the man power for the mainsail and boom can be forgotten.
  • the fixing element on the sailboat of the invention and their positions as well the voyage distance can be shortened.
  • the jib on the sailboat of the invention is able to function as the rudder for forcing the sailboat to turn into windward direction automatically.
  • the sailboat of the invention can simply release its left and right jibs from their corresponding fixing elements for enabling the two jibs to expand and thus to be used as spinnakers. If it is intended to use a spinnaker on a sailboat of the invention, the spinnaker 9 can be rigged and connected by the use of the two fixing elements disposed respective on the post side and starboard side thereof. Moreover, the expanding of the left and right jibs can be enabled simultaneously with the use of spinnaker, by that the sailboat can be propelled by more wind and thus the sailing speed is increased.
