Before you start, we would like to point out that these calculators are based on empirical data.
They are not intended to perform complex cavitation or efficiency calculations.
The results provide "best size" propeller dimensions based on your input data.
There will always be a number of propeller size combinations that will work on your vessel, finding the best one is the trick.
These calculators will help guide you to determine various combinations of power, gear ratio and propeller size for your vessel.
Due to the nature of these calculators, Victoria Propeller Ltd. will not accept any liability, financial or otherwise, for the calculations or results provided.
Propeller Size Calculators:
- Planing Hull Propeller Sizing Calculator
(generally applies to power boats with no keel)
- Displacement and Semi-Displacement Hull Propeller Sizing Calculator
(generally applies to boats with keels)
- Minimum Propeller Diameter Calculator
(good for checking the propeller diameter against the hull size)
