Makes sense. I just tow the dinghy, but I can't leave it in the water as it gets yucky really fast. Lifting to the deck is hard (90 lbs) something I do for the winter. I need a quick and easy way to lift the boat and keep it off the water for a week or two, but I wouldn't mind towing still when underway.
Someone at the marina has a narrow scoop step and uses that to rest the side of the dinghy on while at the slip.
