Propeller
technology has essentially not changed for many years. Yacht
masts, hulls and many other features of marina technology has
turned to carbon fiber and now we have Contur®
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.
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 |
 |
One of the
distinguishing features of the carbon fiber propellers is their
ultra lightweight due to the use of advanced composite
materials. 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®
propeller is extremely quiet and free of cavitation. |

Contur® - Improved acceleration and reduced fuel consumption |
|
|
Another unique
feature of the Contur® 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 in quicker acceleration. |

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 relatively low, enabling the Contur® propeller to adjust to it's maximum pitch.
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%. The Contur® propeller provides faster acceleration
along with a significant reduction in fuel consumption. |
