Remove it
Your question is a litle unclear. I remove my genoa, inspect it, fold it and store inside for the winter. I drop the mast and remove all the standing rigging from the deck, including the roller furler, and hang it from the rafters of the garage. I inspect the shrouds before I put the mast away. I also brace the furling foil and drum so they do not get damaged. I have a C22. If I had a larger boat that was stored at a marina with the mast up, I would still remove the foresail and get it out of the weather.
