I have an old set of beachwheels that have served me well for my hobie 16s and my Prindle 18. However I just purchased Prindle 18-2 and figured it was probably not a good idea to wheel it around without the cradles. I was on the online store but could not figure out which ones would be appropriate for the boat and would fit over the axles of my current setup. Could someone help?

Thanks Pete
