Re: Winch covers?
My family's boats have always had them and so have my boats. But lately I've questioned it too. There really isn't much of anything to corrode - the winch is chrome plated bronze and covered in grease. Only the springs and pawls are steel, and they're slathered in grease too.
My car stands a better chance of corroding and it doesn't have a cover.
