This is our most durable boom, with superior uv resistance, tear resistance, and tensile strength. It is the ideal boom for permanent installation in calm to slightly choppy waters and requires little or no maintenance.

Fabric is 144-oz/sq-yd, PVC-coated, polyester belting, impregnated with marine-growth and ultraviolet inhibitors.

Sigma Boom floats are foam-filled shells, molded from 1/8-inch, heavy-duty polyethylene with ultraviolet and marine-growth inhibitors. The floats provide high visibility, high impact resistance, reserve buoyancy-to-weight ratio, wave conformance, and wind stability. Ballast is provided by lead weights riveted to the fabric.
