Great project dolly.I made a dolly for my Sunfish ... It was easy to build, cheap ...
Here's a concept...My next plan is to build a similar one to your's, out of PVC and balloon tires.
Does anyone have any info/pics/videos on making your own daggerboard dolly - primarily for soft sand transport?
I thought these foam-filled tires looked pretty sweet, and at $18 each, were pretty reasonable. I plan to make a dolly similar to the concept one Wayne showed earlier, and will probably buy these wheels to do it.
