My dad told me this story. He worked in construction most of his life. There was this guy that worked with him that only worked 9 months out of the year. The other 3 months was spent sailing with his wife. One night they were anchored in the carribean sea and the guy heard a bump hit the boat. He woke up, got his gun. Sure enough, there was an intruder boarding the boat, in scuba gear. The owner of the boat shot the intruder pushed him overboard then sailed away. End of story.
