I just purchased a sunfish, and will keep it on a lake where everyone pulls their boats out and up the shore to an area when they can be locked to a chain. I need to build a set of wheels on a little cradle that I can slip under the boat and to which I can strap the boat on, so I can pull her by her bow 20 or 30 feet. Have any of you made something like this before? Do you have pictures or plans you can share? Is there an easier way??? Thanks much.
