>It would seem that regen speed is going to be very dependent on the design of the prop , motor and optimizing for your boat.
That is so true. You can optimize the EP setup for speed, range, power or regen. I changed my controller a while ago and it came aimed at power more than regen. With my original controller (Sevcon Millipac) I would get 100-200 watts (2-4 amps at 52 volts) of regen regularly. With the new controller (Sevcon Gen4) I get half that. I will probably change that at some point. Its not a lot of power but its constant. Its fun watching the voltage climb the longer you are out sailing
