I bought the Quiet Torque 10.0 package from Electric Yacht a couple years ago for my 1979 Catalina Mk1. The Boat had been sitting on a trailer unused for 28 years and she turned out to be a MUCH bigger job than I had originally expected! The good news is she is finally approaching completion 100% renewed from stem to stern and is a functionally new boat. She is going to be a showboat for an enterprise my business partner and I have just launched called Net Zero Marine.
