I'm currently working on an electric saildrive of my own making. My intention is to start with a product best suited for daysailers. I hear a lot about how prop diameter for sailboats that "the bigger, the better". My understanding is that the prop size and pitch should make it possible to spin the motor at the right RPM to maximize the motors top end power. Not too slow so to avoid overload and not fast as to overrun the motor.
The thing I want to know is should I use a prop that is best suited to match the motors max power or should I go with an oversized prop with maybe a reduced pitch?
If this helps, the sailboat would typically be up to 27ft and 5,000 pounds. The idea is not to push for hull speed but more likely 4-5 knots so as not to have to push water.
Thank you in advance.
