By back issues are making me think about keeping my boat in a slip vs on a trailer . I am very concerned about security of my electronics . I am invested in 3 Furuno units that are mounted to the top of my dashboard. If I were to keep my boat in a slip I want it to be around Chesapeake Beach . I know each marina has different levels of security but I know the best level of security is not to have them mounted to the boat and remove them at the end of each trip. So what does everyone do ? I do not want to rely on insurance and fight that hassle . I had to do that with a car and would like to avoid that . I am really interested on what to do. ??
