The beach i pull my catamaran up on has a ton of golf ball size rocks and when i pull the boat up i cant stand knowing what those are doing to the bottom of the boat. I dont fully pull the boat up on the beach, only the front half just so i can throw the sail on and get ready. Does anyone have a solution to this. I know a lot of people use cattrax but this seems pointless because im not pulling the boat fully out of the water. Thanks
