Secure the tow bar in your receiver

I discovered,quite by chance, that hitch balls can also come loose when least expected. I was hitching my Seaway 18’ Sportsman CC to my truck when I just happened to notice what I thought was a movement in my ball. Upon closer,heart stopping inspection, I discovered that I could unbolt the ball bare handed. I removed that ball and replaced it with a new ball with a nylon lined lock bolt secured with a heavy cotter pin. I now check my hitch AND ball before every use. This is the first incident of this kind I’ve ever encountered in over fifty (closer to 60 than I care to admit) years of towing boats,campers and cargo trailers. While receiving a visit from a trailer hitch could prove painful, I would have to assume that 3-4000 pounds of boat,motor and trailer popping through a windshield would be devastating.
