[howard_khoo]

Do anyone know what kind of shape of a propeller will make the most turbulence?

any website that show the calculation on a effect of a propeller?
Any pictures will help!

Thank you

Please write your question better. a propeller makes turbulence when it turns but doesn't move the boat. All propellers will make some turbulence. Moving you hand through the water makes turbulence. Why do you want to know which makes the most turbulence?
