Re: Looking for alternatives to sailing with an engine...
I have cruised without an engine. You can't keep any kind of schedule, which is fine if you have no constraints on your time and don't have to be anywhere at any given time. I remember days when I did not cover more than a few miles. No wind, fairly steady rain. Pull up the anchor when the tide was going the right way. Drift on the tide for a few hours and then anchor again. Repeat as necessary.
The cure for everything is salt water - sweat, tears, or the sea
