Probably all good suggestions, but I have to say that I have never seen a marina with what I would call "secure" parking. Of course, I used to work in the security
field, so I have some pretty well set opinions about what is required to make a place secure.
When it comes to marinas
, there usually isn't even a fence around the parking area. If there is it probably isn't locked. If it ever does get locked I have NEVER seen one that had any sort of regular patrol. So, bottom line, I sure wouldn't leave anything valuable in the vehicles.
