I have a 9' Scadden pontoon that weighs about 75#. I bought the wheel from Kauffman's to attach to the boat and it works well. I got stuck in the wind on Nunally with broken oar right and had to cover a lot of desert with the boat. It was a b%#*ch. About halfway back, I left the boat and carried the back basket I attach with the anchors and my fly rods. When I got back to the boat, I was amazed at how much easier it was to push through the soft stuff. It makes me think about bringing a back pack to carry some stuff and unweight the boat...... Wayne
Here is another option to consider. http://www.launchinggear.com/Launching Gear.htm Not cheap but well built. Saw on on a guys toon a few year ago.
that looks a good option - you aren't kidding though - it is spendy. It makes me wonder why the 'toon manufacturers don't just make something similar.
I use a wheel barrow. So far no one has decided to steal the wheel barrow from me while I was on the lake fishing. Go figure, no one wants to work, and leaves the tools for manual labor alone.
In Too Deep, great design, im working out a bike tire wheel for my pontoon and i might just incorporate your design into it.
