I confess that my boat has a fixed 3-blade prop....Your GPS experiment is interesting, and I'd like to hear if you do it. I thought a fixed prop represented a loss of about a knot or so of boatspeed on average.
This thread interests me because it is related to the idea of self-sufficiency. If one has an all-electric system on a boat and enough power can be generated to run it without outside fuel sources, that would be very interesting indeed, particularly in this world of dwindling resources.
My goal is to live aboard a boat when I retire. Looking forward at what systems such a boat might be equipped with will require much thought.
