This popular design of pontoon using a galvanised steel frame with a hardwood deck and supported on fibre concrete floats is still widely used, although many details have been improved over the years. The design has the following features: • All-welded mild steel structure with a heavy duty 180×75 channel on all walkways. • The structure is hot-dip galvanised in one piece to B.S. 729. • Proven record of Walcon fibre concrete protected expanded polystyrene floats. • A modular pontoon system suitable for most layouts. • Fingers adjustable in position at 500mm centres. • Hardwood deck and fenders. • Full provision for the increasingly complex service requirements of modern marinas. • Various freeboards and live loadings available. SYSTEM 21 THE ORIGINAL WALCON PONTOON DESIGN NOW IN USE FOR NEARLY THIRTY YEARS Dun Laoghaire Marina Ireland DURABILITY System 21 is one of the strongest pontoon designs for marinas. It has withstood for many years the severe test of forming the temporary marina at Southampton International Boat Show. The combination of welded frame units and flexible connections give a durable design. Where galvanising is not considered adequate, such as in more corrosive environments than the United Kingdom, an additional or alternative paint treatment can be specified. SERVICES Services have often been an afterthought in marina construction but easy access to cables and connections during installation and subsequently for maintenance saves money. System 21 walkways may be fitted with continuous ducts along both sides of walkways which give direct access to services and connections without the need to remove decking.
