Abstract: The present invention relates to a floating-type aquatic support apparatus and, more specifically, to a floating-type aquatic support apparatus capable of supporting a heavy marine structure by horizontally maintaining same. The floating-type aquatic support apparatus, according to the present invention, comprises a ball, a floating means, a support, and a supporting means. The floating means has a floating part of which an upper plate supports the ball such that the ball can rotate, the inside is formed of an empty hollow, and a lower plate is provided with a spherical portion. The support is coupled to the ball, and has one end which is exposed to the water such that a structure can be mounted thereon and the other one which is erected vertically and is heavier than the one end so as to be accommodated inside the floating part. One end of the support means is mounted at the bottom of the support to support the support, and the other end of the support means is in rolling contact with the spherical portion. According to the present invention, the support means supports the support on the lower plate of the floating portion. Thus, the load acting on the support is supported by the upper plate and the lower plate of the floating portion, thereby preventing an excessive load from acting on the upper plate.
