I'm studying a possible conversion to electric of my 35-year old full-keel sailboat. But the variable on which I'm having the most trouble finding experience-generated data is prop selection.
I'm aware of prop calculators out there, such as VicProp, but can anyone in this group report on the success of lack thereof, in the actual experience of using a calculator to make a selection?
Did you use VicProp or some other calculator to choose your electric-boat prop, and how did it work out?
If you are using an existing or stock propeller with your electric boat system, what are its specifications (# of blades, diameter, pitch, & mfg.); what power output is your motor (Kw); Max RPM/Reduction ratio (propeller RPMs in other words); and performance?
I'm aware of the data sheet available on this group, but the prop information is spotty. However, mainly, I'd be interested in hearing of anyone's experience with a prop calculator, and which one.
Any help out there?
