[0002] At present, a sailboat is a boat that uses wind power to move forward. It is a water transportation tool. With the improvement of living standards, more and more people like to take a sailboat in their spare time and do water sports. Sailing boats are classified according to the hull, into monohull sailboats and catamaran sailboats. Among them, the hull of a monohull sailboat is a whole, and the catamaran sailboat has two hulls, which are connected into a whole by a beam.

[0003] In the related art, the catamaran sailboat of patent CN211196503U is as follows Figure 1 to Figure 4 As shown, in order to facilitate disassembly and carrying, the two hulls 100 of the catamaran are arranged in sections and assembled when needed. Specifically, the hull 100 includes a bow 1001 and a stern 1002. The bow 1001 and the stern 1002 are first clamped together by a tenon structure 101, and then tightened and fixed in two directions at the bottom by a connecting rod 103, and fixed at the top by a connecting plate 10. The two-way tightening and fixing of the connecting rod 103 specifically includes: a fixing slot 105 is set on the side of the bow 1001, and an insertion hole 106 for inserting the connecting rod 103 is set at the corresponding connection of the stern 1002, and a connecting rod fixing cover 107 is set in the fixing slot 105, and a detachable fixing hole cover 108 is installed on the fixing slot 105. A cap with a diameter larger than the connecting rod is provided at one end of the connecting rod 103, and an embedded nut is provided at the other end. The connecting rod 103 is connected to the connecting rod fixing cover 107 by screws and the embedded nut of the connecting rod 103. Furthermore, the bow 1001 and the stern 1002 are connected by means of a mortise and tenon structure 101, a nut is embedded in the top surface of the mortise and tenon structure 101, a connecting plate 104 is provided above the mortise and tenon structure 101, screws are inserted into the connecting plate 104 and connected to the nuts on the top surface of the mortise and tenon structure 101, thereby fixing the bow 1001 and the top of the stern 1002 together.

[0004] However, when assembling the bow 1001 and the stern 1002 of the catamaran, the connecting rod fixing cover 107 is first coaxially fixed to the front end of the connecting rod 103 in the fixing slot 105, and then the fixing slot 105 is covered by the fixing hole cover 108. The connecting rod fixing cover 107 is coaxially fixed to the front end of the connecting rod 103 in a narrow space, which makes the operation and assembly difficult, and two processes are required at this position, namely, first installing the connecting rod fixing cover 107 and then installing the fixing hole cover 108, so the assembly efficiency is low; at the same time, the two hulls located in front of the front beam have no transverse connection relationship. In actual use, it is found that after long-term use, the front sections of the two hulls without a transverse connection relationship will undergo transverse deformation, which is not conducive to navigation.
