When the United States Navy required a heavy-duty dock to moor its state-of-the-art M80 Stiletto, it worked with SF Marina USA. The resulting 82-ft floating SF 1230 Concrete Dock can perform in the harshest marine conditions. Designed for conditions at the Little Creek Amphibious Base in Norfolk, Va., as well as its future location at NAS Norfolk, the SF 1230 Concrete Dock is engineered to handle extreme wind, tides and waves. Constructed from reinforced concrete and Styrofoam, it offers unmatched strength, stability and buoyancy.
