Sailboat

Abstract

A sailboat is provided, which could use left and right jibs alternately to operate the sailboat without using mainsail. The advantages of sailboat are the shorter route to the destination, and more efficiently and economically in production. The mast of the sailboat is set on the centerline of the sailboat. A function of helm that turns the sailboat towards the windward can be substituted by hanging the jib on the mast set from midship to stern in the centerline of the sailboat. In addition, when the sailboat sails downwind, one end of each jib on the starboard side and the port side could be untied to make jibs become spinnakers. If sailor wants to use a traditional spinnaker, it also could be rigged by connecting the traditional spinnaker to the mast-end and the starboard side and the port side.

1 . A sailboat, comprising:
 a hull module, configured with at least one hull;   a mast, configured with a first end and a second end at positions thereof opposite to each other while coupling the first end to a position on a center line of the hull module as the center line is defined to be a line connecting the center of a line passing through each bow of the at least one hull and the center of a line passing through each stern of the at least one hull;   a first fixing element, disposed at position on the left to the center line of the hull module;   a first winch, disposed at position on the left to the center line of the hul module;   a first jib, configured with a plurality of ends including a first end, a second end and a third end in a manner that the first end of the first jib is connected to the second end of the mast, the second end of the first jib is connected to the first fixing element, and the third end of the first jib is connected to the first winch;   a second fixing element, disposed at position on the right to the center line of the hull module;   a second winch, disposed at position on the right to the center line of the hul module; and   a second jib, configured with a plurality of ends including a first end, a second end and a third end in a manner that the first end of the second jib is connected to the second end of the mast, the second end of the second jib is connected to the second fixing element, and the third end of the second jib is connected to the second winch.   
     
     
         2 . The sailboat of  claim 1 , further comprising:
 a boom, configured with a first end and a second end at positions opposite to each other while enabling the first end thereof to coupled with the mast;   a mainsail, being configured with a plurality of ends including a first end, a second end and a third end in a manner that the first end of the mainsail is coupled to the second end of the mast, the second end of the mainsail is coupled to the first end of the boom, and the third end of the mainsail is coupled to the second end of the boom.   
     
     
         3 . The sailboat of  claim 1 , further comprising:
 a first pulley, disposed at the port side of the hull module to be used for enabling the third end of the first jib to pass therethrough before being connected to the first winch; and   a second pulley, disposed at the starboard side of the hull module to be used for enabling the third end of the second jib to pass therethrough before being connected to the second winch.   
     
     
         4 . The sailboat of  claim 2 , further comprising:
 a first pulley, disposed at the port side of the hull module to be used for enabling the third end of the first jib to pass therethrough before being connected to the first winch; and   a second pulley, disposed at the starboard side of the hull module to be used for enabling the third end of the second jib to pass therethrough before being connected to the second winch.   
     
     
         5 . The sailboat of  claim 1 , wherein the hull module is formed as a monohull structure; and the first fixing element is disposed at the gunwale of the port side of the monohull structure while the second fixing element is disposed at the gunwale of the starboard side of the monohull structure. 
     
     
         6 . The sailboat of  claim 1 , wherein the hull module is formed as a multi-hull structure; and the first fixing element is disposed at the bow of the most left hull in the multi-hull structure or the gunwale of the port side of the most left hull in the multi-hull structure while the second fixing element is disposed at the bow of the most right hull in the multi-hull structure or the gunwale of the starboard side of the most right hull in the multi-hull structure. 
     
     
         7 . The sailboat of  claim 1 , wherein the first end of the mast is coupled to a position on a center line of the hull module and the center line is defined to be line connecting the midship of the hull module to the stern of the same. 
     
     
         8 . The sailboat of  claim 1 , further comprising:
 a spinnaker, configured with a plurality of ends including a first end, a second end and a third end in a manner that the first end of the spinnaker is connected to the second end of the mast, the second end of the spinnaker is connected to a position at the left of the center line of the hull module, and the third end of the spinnaker is connected to a position at the right of the center line of the hull module.   
     
     
         9 . The sailboat of  claim 8 , wherein the second end of the spinnaker is connected to a device selected from the group consisting of a first fixing element and the first winch; while the third end of the spinnaker is connected to a device selected from the group consisting of a second fixing element and the second winch.
