Description

  The present invention relates to a surfboard provided with an auxiliary device, and more particularly to a surfboard with an auxiliary device for stabilizing the surfboard horizontally so that the surfer does not fall off the surfboard.

  In general, in surfing, a surfboard is used to ride on a slope formed on the shore side of a wave from offshore to the shore, and the surfboard is pushed by a moving wave so as to slide on the surface of water near the shore. A surfer must ride a wave while manipulating a surfboard that is tilted by a slope on a moving unstable water surface, and a specific sense of balance and strength are required.

  Therefore, surfing beginners are likely to fall off the surfboard due to lack of balance and muscle strength as described above.In general, paddling movement from the shore is limited to shallow water rather than offshore, making the surfboard a small wave flow Repeat the practice of getting on the surfboard and moving to the shore. Small waves generated in the shallows are generated by breaking offshore large waves, but the thickness of the waves is not so thick, but there is some momentum, and if you put a surfboard, the surfer will move almost horizontally to the shore side by the flow Carry. At this time, since the surfboard is only on the surface of the wave that is not too thick, if the surfer's sense of balance is bad, the surfboard can not ride cleanly, causing the surfboard to fall from the surfboard, or the speed of the surfboard It will be late.

  In general, it takes a long time to develop balance and muscle strength by repeating such exercises. During this time, you can't enjoy the pleasure of riding the original wave surf.

  Therefore, various auxiliary devices have been developed so that even surfing beginners can enjoy surfing sufficiently. For example, there are known surfboard propulsion assist devices that can efficiently provide propulsive force (Patent Documents 1 and 2), daggerboards that have tail fins attached to the surfboard as auxiliary power (Patent Document 3), and the like. It has been.

  However, these surfboards with auxiliary devices also require practice until they are used to the end, and are insufficient to solve the above problems.
