A floating module includes an upper half and a lower half. The upper half includes one edge from which a flange extends downwardly, while the lower half includes an opposite edge that includes an upwardly facing flange. Modules can be interconnected to one another by engaging the upper flange from one with the lower flange from another. A cavity and channels are formed in the lower surface of the module such that water will become entrapped in the cavity and channels when the platform is placed in water. Through use of one way check valves positioned in fluid communication with the cavity and channels, a hydro-lock is formed that prevents the water from escaping the cavity and channels while it is placed in water.
