That can come later, if it survives. I know of a Cape Dory 33 that survived Katrina up in a canal, that was trapped in it for almost a year, because so many trees had fallen across the canal and blocked it. But, we weren't doing much sailing for a year after Katrina, anyway (too much debris in the water).
