    This is my C22 with an Elco 9.9, and 2 48v 100ah batteries. It runs a nice 5 knots on 1200 watts an hour. Now I'm working on a solar canopy so it will recharge while sitting on the trailer.

    Interesting project, thanks for sharing!

    Can you provide more details on the batteries used and real-life range?
    Did you modify the keel and/or ballast?

    Please keep us updated on the canopy installation.

    The batteries are Ampere Time 48volt 100Ah LiFePO4, they weight about 100lbs each. I was able to sneak them into the bilge just aft of the keel. The keel is still in place, and I am still trying to decide if I should remove it. All of the sail gear has been removed. It sits a little low aft now but runs and handles great. With 4 hours running time from idle to full throttle, I can say that the 9.9 is bigger than is needed. 5.6 knots is all it will do, which is just a bit over 1/2 throttle. I held it at steady 5 knots for an hour, using only 1200 watts. There is almost no wake even at 5 knots. That should give me an easy 7 hours running time, with a little to spare, even without the solar panels. The Elco outboard has a whine, but not too troublesome. I am extremely happy so far.
