Re: Public Dock issues
sort of like asking about parking a car in a public parking lot. The only answer is, it depends.
I know public docks where you can leave the keys in the ignition; another is so unsafe you don't want to use the ramp at night unless you are packing.
I think generally, boaters tend to be honest with other boaters. It's the non-boaters who may have easy access to the dock that will be the problem. So evaluate how open it is and how much it's used by the non-boating public--teen hang-out, right off a busy street, etc.
