Storage

I have an older 1994 14’ Laser on a lake in South Carolina. The shoreline is very rocky. I was storing the boat on whips by my dock, but am getting bumbs on the hull. I am older and can’t lift the boat myself. Suggestions on summer storage on the shoreline? On it’s side? On the beach on it’s hull? I admit, I am not sure what to do with this boat so it’s launch-able when the wind comes up-
