If anyone was doing a float blind on a big private body of water, this would be a good platform. I think they made a mistake and got circumference and diameter mixed up but you can see what you get. This can be made as wide as you want it making a very large paw print.

My uncle built two floating blinds with pontoons. We used them a lot when the property flooded. They did a lot of welding to build the frame. One had very big pontoons, we were able to pull the boat under the blind. Both blinds had electric winches that operated an anchor. We also put skids on the bottom of the pontoons so we could drag them out of the rice fields after season.
They worked really well. The best part was the ice chest and propane camp stove we would have in the blind. Slow morning weren't too bad when breakfast was cooking.
