Polyline Industries’ range of Polyethylene (Poly or PE) boats are great alternatives to aluminium commercial work boats. As we specialise in poly fabrication we have proved it to be a cost-effective material for commercial boats for purposes of Fast Response, Search & Rescue, Patrol, Maintenance and Research.
Features & Benefits of Polyline’s Commercial Boats
- Lightweight
Vessels built of PE can be three times as thick as aluminium for the same weight or built much thinner and lighter.
Being lightweight means the boat is considered positive in the water as it naturally floats.
- Strong & Non-Corrosive
Polyethylene (PE) is inert which means the molecular structure is full, and therefore will not rust or corrode and does not suffer from electrolysis.
- Performance
PE has a low friction co-efficient (0.02) which results in less drag, making for better performance and fuel efficiency.
PE is relatively light with an S.G. of 0.92, approx a third of the weight of aluminium (S.G. 2.7) meaning it has positive buoyancy.
- Impact Resistant
As polymers are long chain molecules they give plastics a memory resulting in high impact resistance unlike metals or glass which have crystalline type structures that dent or fracture.
PE will also not scratch or damage other vessels or infrastructure.
- Low Maintenance
Vessels constructed of PE do not require coating or painting.
They are low maintenance as the PE is inert and therefore has no porosity ensuring that marine growth cannot penetrate the polymer.
Although marine organisms like to grow on polymer they cannot effectively attach or penetrate making them easy to remove and therefore anti-foul is not required.
- Durable / Long Life
Polyethylene is UV Stable ensuring a long working life.

• In Ausmarine’s article our client was quoted saying that their POLYRIB “has proved to be a quality vessel that performs all duties and tasks better than expected” followed by “Vermillion Oil and Gas Australia would have no reservations in recommending Polyline to any company wishing to pursue a development project with their organisation”.
• The PolyRIB 6300 was also named in the Top 20 Vessels of 2009 by Work Boat World. It outlines that Polyline Industries claimed a series of innovative firsts with further explanation that the POLYRIB is “the world’s first polyethylene craft to be based on an oil platform; first waterjet-diesel in its size range, the first waterjet installation to use a plastic jet intake” and the first and only combined response craft in Australia.
