Re: HELP: Zodiac Futura Reviews...
just found these...

though they are only rated to 200kg but look a lot stronger looking than the zodiac ones. I would have thought they could take 200kg each! I wonder if its because they fold?! either way they are a simple design and I am sure I could make a similar set up but a none folding version and thus stronger!
Do you have access to a Tig welder, drill press, grinders (Many), files, burrs, air tools, etc.? If not buy a prefab pair of wheels. I just built a "simple" pair of transom wheels for my boat. It took a lot of man hours, cost around $350 US dollars, and took a ton of tools most people do not own. For me there was nothing available that would roll across a soft sand beach, so I had to build my own setup utilizing 49cm Wheeleez tyres. You could have a professional welder build you pair for a large sum of money that would work excellent. We have a stair step at Point Lobos, one of our launch ramps, during ultra low tides, I am hoping won't be a problem recovering over anymore.
My recommendation get the largest diameter, heaviest duty transom wheels you can find that are bolt on.
Forget the 2 ton little winch thing you posted (I own one and know how they work). It will take an hour to get the boat clear of the water and have to be set up numerous times blocking the boat wheels while reconfiguring. A simply pulley system is your best bet. You can easily soft lock it off, or if you wanted can get a Halkey pulley setup that has a rope clinch installed on it.
