ARE YOU STILL IN THE BRONZE AGE!

 

Propeller technology has essentially not changed for many years. Yacht masts, hulls and many other features of marina technology has turned to Carbon fibre and now we have Contur carbon fibre propellers.

Contur Marine Propellers - the propeller with exchangeable blades

We have subsequently developed a range of marine propellers under the registered trade name of Contur. Each propeller is fitted with separate exchangeable blades, constructed of advanced high strength carbon composite materials.  Removable blade diagram

There is also a NEW high performance intelligent propeller. This is a unique lightweight, low noise propeller with individually replaceable blades, should any of the blades be damaged, thereby avoiding the costly expense of replacing the entire propeller.

Contur - A low weight and low noise propeller

Up to 60 to 70% reduction in weight is achievable in comparison to a conventional propeller. In addition due to the unique design of the low profile blades, the Contur carbon fibre propeller is extremely quiet and free of cavitation.

Contur - Improved acceleration and reduced fuel consumption

Another unique feature of the Contur carbon fibre propeller is the flexible pitch of the propeller blades, which provides quicker acceleration. The pitch of the blades adjusts automatically as load is applied, enabling the engine to reach its top RPM quicker than a conventional propeller. This is described, as an "intelligent" propeller resulting is quicker acceleration.Contur propeller performance chart

Contur - Flexible blades.  

The flexibility of the blades allows the yacht to achieve her top speeds at lower RPM rather than full throttle. Under such conditions the load on the propeller blades is therefore relatively low, enabling the Contur carbon fibre propeller to adjust to its maximum pitch, and by doing so the vessel reaches the required speed at a lower engine RPM, which in turn means lower specific fuel consumption. On average a 15% reduction in fuel consumption can be achieved. Less fuel consumption means an increase in range of approximately 15%. All in all the Contur carbon fibre propeller provides faster acceleration with along with a significant reduction in fuel consumption.

Certification - ISO 9001

Designing such advanced carbon fibre propellers is not enough but obtaining certification is the ultimate in product recognition.
