Polyline Industries of Western Australia is one of the world's originals in the field of plastic leisure and commercial vessels. Others have jumped on to the bandwagon, but Polyline keeps pushing the technology - extending in type, size and complexity- and maintains a comfortable edge. It is an edge they established years ago in the underground mining industry when founder David Wilkie realised that the high cost of constantly replacing corroded steel ventilation shafts could be eliminated by usingplastic. Now thoroughly established in the marine industry as well, Polyline has produced a string of workboats, oil-spill control vessels and containment barges. The latest vessel is the company's biggest, a 250-tonne-capacity barge. Polyline believe it could also be the world's largest plastic vessel.
