Back when my boat was built (1990) the main halyard was made of wire and rope with a wire to rope splice. Some time ago a previous owner changed the main halyard to all rope. One day, while we were running downwind the main halyard parted and down came the main. As it turns out, the design of the exit for the main halyard at the top of the mast is made for a wire halyard so has a different design of exit than the jib and spinnaker halyards at the front of the mast. There are bars on either side of the halyard exits at the front that soften the exit that don't exist at the back.
I asked the local rigging shop for suggestions for how to prevent this from happening in the future. His answer was "You don't really race the boat so why not go back to a wire and rope halyard?" We did and so far no problems with halyards since. Ken H. On 21 October 2013 22:02, David Paine <paineda...@gmail.com> wrote: > Thanks for the ideas.
