Pactrade Marine Flip-up Retrackable Dinghy Wheels Pair Nylon Inflatable Boat Launching Wheels/Boat dolly

Has anyone tried to install these on 10' pelican bass raider or similar style plastic pontoon boat?

I see they can be used for inflatable boats. How do u attach them?

Will these work for a 13' Ascend 133x kayak? Would mounting directly to it in the back compromise the area or the yak's plastic over time and use?

How wide are these wheels?
