We've been in the same small marina for about 14 years with a progression of boats. Our slip is on the last finger of the last dock, so while quiet and private it's also out of sight. Neither we or any other boat has ever reported any theft or break-in and those of us who overnight are the minority so it's generally quiet. We've had three "incidents", the worst being malicious vandalism. Someone aboard a small boat or dinghy removed the cotter pin from the prop shaft of our outboard kicker. The nut unscrewed itself backing out, the prop's thrust kept it in place until we cleared the channel and when the sails took over the drag pulled the prop off and sent it to Davy Jone's locker, which made for an interesting return through a serpentine channel. The second was a fisherperson deciding to use the cockpit as a comfortable fishing dock, but left all the attendant dead bait strewn about. The last was an act of nature. A raccoon, having gorged on either wild cherries or hackberries became intestinally challenged and was looking for a corner to relieve itself. Last finger-last dock=last corner. The cockpit became the center of projectile crapping, wall-to-wall. That required a trip to the fuel dock and a pressure washer.
