I am purchasing a Mariner 4 and have been looking at the mods peoples have done. One of the items I am interested in is the launch dolly made with PVC pipes. Having to self launch the boat this dolly would be helpful. Can anyone provide the specs on the dolly they built for theMariner 4.
Thanks

I made one out of some old 2x4s and scraps of plywood. You can roll it right down a launch ramp or even a beach to get the boat into the water, and haul it out the same way. You can also put the handle of the dolly on the tailgate then just pick up the back and slide the whole dolly and boat into the bed of a pickup. It floats too, so if you let go of it on the launch ramp you can still retrieve it without going swimming.

Thank you your Dolly looks interesting most of the ones that I have seen were PVC pipes and not wood. Need it to fold up as small as possible don’t have a truck just an SUV.

All depends on how long your dingy is. I made the dolly a bit longer to accommodate a 12' long one. You could definitely build a similar one with two sections that slide out instead of one, so it collapses down to a smaller size. Could have also used 1x4 wood instead of the 2x4 that I used (only because I had it laying around).
