Abstract: A floating body to which an aquatic or marine facility is installed or which is connected to a lower part of the aquatic or marine facility to hold the aquatic or marine facility on water or the sea is proposed. The floating body may include a main floating body which floats on water or the sea by using buoyancy, and a magnet provided on a first vertical side of the main floating body. The floating body may also include a coupling member provided on an opposite vertical side of the main floating body by corresponding to a magnet of another floating body such that the coupling member is coupled thereto, and a mooring line installed on a part of the main floating body to moor and hold the main floating body on water or the sea.
