M_Boats: Towing safety reminder from my experience

My crew and I had a bad experience while returning to Sacramento area from a Potter event in S.F. bay last year. Bottom line: Be sure you drill a hole in the threaded part of the trailer ball and insert a cotter pin blow the nut (or purchase this type). We ended up dragging my M15 and trailer by the safety chain at 60 MPH on I80 East due to a malfunction! The nut and a new lock washer came off despite tightening it with an 18" crescent wrench. It is a long story, but please, ALWAYS HAVE THE SAFETY OF A COTTER PIN UNDER THE NUT! PS: Don't tow Ericksons. And jerry, of course you're forgiven (funny, it could have happened to any of us) Bruce King M15 Fair Oaks,CA
