CompuQuin

 

Propulsion optimization at it's best !

With today's trend towards large high speed craft using lighter construction materials and fitted with higher horsepower engines, new frontiers of propeller design have been demanded by astute users of these vessels. To meet this challenge Austral has now developed a complex five bladed propeller design to specifically suit these new and demanding applications.

The revolutionary CompuQuin five blade design has very efficient large wide blades, which significantly reduces the slip of high speed craft normally caused by excessive propeller loading (ie basically the propeller is too small for the size and power of the boat). This five blade design is produced from CNC machined patterns which ensures exceptional operational smoothness. CompuQuin has repeatedly proven a real winner when fitted to premium high speed pleasure or commercial boats.

CompuQuin 5B propellers are available from 14" - 52" diameter, in both right and left hand rotation and in an extensive range of pitch sizes.

Design Features:

Performance Advantages:

* CAD/CAM computer developed

* Maximum thrust for minimum diameter

* Multi blades for smoothness

* Overcomes excessive propeller loading

* Five large blades for efficiency

* Ideal for restricted diameter aperture

* Varying pitch distribution

* Reduces slippage and cavitation

* Patterns fully CNC machined

* Incredibly smooth in operation

* Disc Area Ratio = 0.96 maximum

* The ultimate propeller for fast premium boats

* Electronically balanced

* Individually pitchometer checked

* Super Cup design also (Nibral only)
