I've been hanging rags for a long time. But, recently have been considering the "dark side" especially fuel efficient trawlers. And, I'm very interested in new battery technology and electric motor hybrids for boaters.
I can not even think of engines. Engines and I just do not mix. I contemplate oars or poles to move my sailboat. At the moment my engine needs to be diagnosed. With a pole I can tell if it is not long enough or broke. I wish you fair winds.
