Abstract: A float structure includes a flotation portion, a frame portion, a shell portion and a connector portion. The flotation portion includes a unitary porous slab member having a generally quadrangular configuration and includes upper and lower major faces and sidewalls joining same. The sidewalls taper inwardly toward the lower major face thereof. The frame portion includes a plurality of elongated interconnected strip members disposed around the periphery of the slab member adjacent the upper major face thereof. The shell portion includes a continuous waterproof covering over substantially the entire outer surface of the flotation portion. The connector portion includes a plurality of spaced fasteners extending through the shell portion into the frame portion and capable of securing bracket members to the periphery of the structure; whereby the float structure may be carried to a body of water and anchored therein at a desired location.
