WALCONSYSTEM 21 PONTOON SPECIFICATIONS Loading: 1kN/m2 - 2.5kN/m2 Freeboard: 500mm nominal unloaded freeboard with 300mm draft, other options available. Structure: All-welded mild steel frame of standard channel sections, cross-braced with rolled steel angles. All hot-dip galvanised to EN ISO 1461 after fabrication. Decking: Ex 150x25 hardwood boards, planed, grooved to give antislip surface and screwed to fenders and spines using grade A4 stainless steel screws. Floats: Standard Walcon floats constructed of fibre concrete protected expanded polystyrene. Connections: The proven flexible couplings comprise compressed rubber blocks with hot dipped spun galvanised through bolts, castle nuts and split pins. This ensures security and prevents vertical and lateral misalignment but allows vertical angular movement of the adjacent units. No noise is generated by the connections. Climatic Conditions: Maximum wave height 400mm Due to a policy of continuous product development, Walcon reserve the right to change specifications without prior notice. TECHNICAL Walking Units (WW) Walkway units may be used for the main concourse of a marina and for many other pontoon applications. Standard lengths are 11.46m and 7.46m; widths 2.56m, 1.93m and 1.65m. Finger Units (SF) Cantilever finger units are used in conjunction with walkways giving individual berths. Fingers are supplied in lengths of 4.5m, 6.0m, 7.5m, 9.0m and 10.5m. Units are made in a splay design with a minimum width of 750mm. Parallel sided finger pontoons are also available with only a small root splay for fixings. The structure of fingers is designed at a minimum length of 75% of the length of the boat. Longer units are available but will be parallel sided and supported by an end pile. Economy Fingers (EF) Lightweight mooring arms with limited access are designed as an economic alternative to 4.5m and 6.0m fingers.
