On my Santorin 1993 I normally use the propeller generator when sailing but to my experience – and practical measurements – it will cut ½ to 1 knot of the speed unless there is plenty of wind. So sailing in modest wind I have chosen to just let the propeller turn free as setting the gear in “back” in order to stop the propeller turning will cut 1/3 to ½ knot of speed.
So my conclusion is that the propeller generator generates significant drag but is a fantastic opportunity to generate all the power the boat needs for both running autopilot, fridge, lights and all navigation equipment – and still have excess power to charge the batteries.
