OK I’ll scrub the towing idea:-) The big fear is capsizing when alone as I am certain I could not right the boat alone. I may have to think about a different boat:-(
All depends which Wayfarer version you have. It is generally accepted that double bottomed self draining versions (Mark 11 SD, World, Mark 4) are very likely to turn turtle and difficult to right without considerable weight. Other versions (Mark 1, Mark 11) are less likely to invert and easier to right from either on their side or even upside down. Righting lines may also be a good idea for singlehanding. I would never go to see in a boat I could not right (assuming it has no keel).
