We use Prop Scan™ to optimize marine propellers

The computerized Prop Scan™ was specifically designed to inspect the accuracy and precise hydrodynamic form of Australian, Canadian and US Navy propellers.
The accuracy and form or shape of a propeller blade section as it slices through the water determines the ultimate thrust and performance of any vessel.

ISO Propeller Standards

The International Organization for Standardization has produced a standard (ISO 484/2) that defines the tolerances for marine propellers. All marine propellers can be placed in a class based on the ISO 484/2 standards.

ISO 484/2 Accuracy Classes

Below is a description of each ISO 484/2 Accuracy Class. Due to Prop Scan's high levels of accuracy it is now possible to repair a propeller to an accuracy level twice the accuracy of Class S. We call this Class 0.

Very High Accuracy

High Accuracy

Medium Accuracy

Wide Tolerances

Fuel Savings

Prop Scan Class O

15 - 20% 80%

ISO 484 Class S

10 - 15% 60%

ISO 484 Class I

5 - 10% 40%

ISO 484 Class II

1 - 5% 20%

Increased Speed

Prop Scan Class O

4 Kts 90%

ISO 484 Class S

3 Kts 70%

ISO 484 Class I

2 Kts 50%

ISO 484 Class II

1 Kt 30%
