It Happens!!!!!!
My "emergency" or "back up" tiller in now in a place of honor under the port cockpit seatand readly acessable on my '85 Hunter 31'. I had heard of other members of my Club having a similar experince but, more importantly,I personally experienced a 2:30 AM break in the Edsel steering cable on a friend's15 year old boat while we were under sail. Fortunatly, he was well prepared. Since then, I retrieved the "back up tiller" buryed under the many lines in my stern lazarette, and put it in a place of "immediate access". Experience is the best teacher!!! Yes I have tried it and it works!!!!
