I have a Catalina Capri that we would like to leave moored in a small harbor on Lake Michigan. I am looking for a cover and any other necessary equipment (eg. boom crutch) that would allow us to leave the boat as rigged as possible between sails. Does anyone have any recommendations? I am wondering if a full cover is necessary, or whether just a sail cover might be sufficient. I will leave the boat moored for about one month each summer. Thank you!
