I'm putting all the plans together for my 38' 48v electric
sailboat conversion project
A fixed prop will be more efficient while on power PLUS provide regen while underway. But a folding prop will be far more efficient while underway, without drag and all the complicated (and more expensive) regen electronics
However, a folding prop is also far more expensive than a fixed one...
So, what would be my best option? Is regen really efficient and at what speeds? Will the motor
underway, making my sailing experience far less pleasurable? Do the increased mechanical complications of a folding prop beat the increased electrical
complications of a regen system?
