Description

Technical Field

[0001] The utility model relates to the technical field of sailboats, in particular to a mast buoyancy aid device for a sailboat. Background Art

[0002] Sailboats are ships that use wind power to move forward. They are an ancient means of water transportation after boats and rafts, and have a history of more than 5,000 years. According to the number of masts, they can be divided into single-masted sailboats, two-masted sailboats and multi-masted sailboats; according to the ship type, they can be divided into flat-bottomed and pointed-bottomed sailboats; according to the bow type, they can be divided into broad-headed, narrow-headed and pointed-headed sailboats. Sailboats mainly rely on sails to navigate with the help of wind power, and rely on oars, scull and poles as a means of propulsion, berthing and sailing when there is no wind.

[0003] A Chinese utility model patent with application number 202220725383.9 proposes a sailboat mast buoyancy aid device, which includes: a mast, two mounting shells are fixedly connected to the front and rear sides of the mast surface, two symmetrical mounting holes are opened on one side of the mounting shell, and the inner cavity of the mounting hole is provided with a buoyancy rod, both ends of the buoyancy rod penetrate to the outside of the mounting hole, and buoyancy plates are tied on both sides of the surface of the two buoyancy rods. The device has the advantages of convenient use and good safety. In actual use, a buoyancy rod is installed on the surface of the mast, which plays a role of providing primary buoyancy support for the mast, and the buoyancy rod is easy to disassemble and assemble, so it is convenient for users to use. By wrapping the buoyancy plate on the surface of the mast, it plays a role of providing secondary buoyancy support for the mast, so that the mast and the sail surface always keep floating on the water surface, thereby reducing the difficulty of righting and possible safety hazards.

[0004] After the improvement, the above device keeps the mast and the sail floating on the water surface at all times by setting up buoyancy rods and buoyancy plates, thereby reducing the difficulty of righting and the possibility of safety hazards. However, in actual use, the wind and waves on the sea are not stable and will cause certain obstacles to people's mobility. When the wind and waves are relatively turbulent, artificially using buoyancy rods and buoyancy plates to maintain the floating state will lead to the problem of untimely operation, which may easily lead to safety hazards caused by the difficulty of righting the sailboat. For this reason, we propose a sailboat mast flotation device. Utility Model Content
