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.
