This 2nd video was filmed in the early fall of 2020 after Shamrock got a complete overhaul on the dry docks and had a large 72V battery bank installed. We went for an afternoon sail to show the power vs speed relationship and demonstrate regenerative energy capture from the propeller under sail.

Unfortunately the instrumented motor mount had to be temporarily scrapped since it wasn't rigid enough and allowed the motor and shaft to wobble, but we were still able to get some precise and useful data right up to 3000 watts just with the Cycle Analyst.

For our next project we will be replacing the Phaserunner with a larger and much more powerful BAC8000 controller from ASI in order to run the grin motor right up 5000 watts. Stay tuned to see the maximum and continuous powers we can get from a simple hub motor in this application!
