Here in the USA I can not find Fellshaw wheels. I will be running my land yacht on hard packed low tide sand. So do I have to go with fat wheels or can I use wheels that are 12. 1/2 inches X 2. 3/4 inches. These are these are high speed wheels off a scooter. I am not racing this, it is just for fun so I have no need to stay in any class guide lines. Any help would be great. Plus big score today I picked up 3 more wind surf sails and 2 more masts for free. That bring me to a total of 7 sails and 5 masts to work with.
