Disclosed in the present invention is an assembly-type small leisure boat. The leisure boat according to the present invention comprises: a boat body on which people board; three or more connection rods of which one end is coupled to the boat body and are symmetrically arranged with the boat body at the center; and floating bodies respectively connected to the other end of each of the connection rods. According to the present invention, the stability of the leisure boat is significantly improved due to the three or more floating bodies symmetrically arranged around the boat body. In particular, the boat body is positioned at the center of the folating bodies, and thereby reduces rocking of the boat body due to movement of users or waves and prevents the boat body from being easily capsized. The present invention also has the advantages of not easily sinking even when the boat body is damaged, easy transportation and storing by to being assemblable, and significantly contributing to enlargement of the base and popularization of water leisure activities by enabling supply at an affordable cost due to mass-production. Furthermore, the present invention can prevent water pollution by manufacturing using environmentally friendly materials instead of existing FRP.
