A modular wave-break includes a wall, a tapered base attached to the wall, and an anchor attached to the base. The wall includes a set of dissipating holes integrally formed in the wall and a set of passage holes integrally formed in the wall. A set of eyebolts are connected to the wall. Reinforcing structural rods are embedded in the wall, the tapered base, and the anchor to provide strength. Mounting holes in the tapered base enable the modular wave-break to be secured to a water bottom surface. Multiple modular wave-breaks may be interconnected to form a single wave-break.
