REFIT & REFURBISHMENT 072 that protects and preserves the look of the teak. We also have a UV- stable teak coating which provides added protection and longevity", says Norris. Below deck on yachts, especially those that are ocean going, the No-Skid products can be applied to any area that requires better grip." When it comes to next generation composites for both the DIY and professional marine markets, Lorraine Murray at ATL Composites says the latest formulae of composite products are good for the environment, suit every budget and are easy to apply. "The product we recommend for repair and maintenance work is the West System epoxy range. These products are used by both professional yards and by yacht owners. It's just a matter of choice and budget", says Murray. There are several repair and maintenance publications that people can buy in hard copy (or download for free from our website) covering a wide range of boats and typical repairs. According to Murray, when it comes to maintenance and repair, there's not a lot of difference between sailing yachts and powerboats. "They are both built from timber, solid fibreglass or composite material, cored and fibreglass construction, so they both have the same problems. Weight is sometimes more important for powerboats to keep the fuel consumption costs down, but then again, weight is critical for racing yachts too. The repair principles and composite materials from our end are similar though." Murray says the choice of products entirely depends on the particular job. "There are specific products such as flow-coat used as a waterproof coating inside lockers that provides better moisture protection than paint." For refits, particularly to save weight or deliver a general "spruce up" inside, ATL Composites sells a range of marine interior panels. Murray explains: "These are lightweight composite panels for non-structural furniture. They are lighter than plywood and can be used as non-structural walls, cabinetry, saloon cupboards and anything that's not load-bearing." Owners often enquire about adding hardtop Biminis to flybridges and aft areas, or extensions of length to transoms or topsides. "For those requirements, we supply structural composite panels (in a standard size of 1200 x 2400 millimetres) which boat builders shape to the required format." For the eco-conscious, ATL Composites has developed a brand new bio-based adhesive that is an environmentally friendly alternative for structural bonding. Known as Techniglue R70, the system was formulated for improved user safety and to reduce the impact on the environment that comes from using petro-chemical based, thermo-set resins. The raw materials that form the base of the R70 system are made from industrially grown and harvested, renewables of plant origin. Natural phenols are reacted to create a natural "green" base epoxy system. Production of R70 consumes less energy and water than standard petroleum based epoxies, and also reduces wastes and greenhouse gas emissions. "Techniglue R70 is tolerant of damp and low temperature conditions and cures to a non-brittle, low-shrink adhesive with good gap-filling capability, with excellent hold-up on vertical surfaces," says Murray. "R70 will bond components fabricated from wood, concrete, fibreglass, PRO REFITS Above: Sydney City Marine's high-tech paint shed.
