On page 121 of Bob Well's "Optimizing the East Coast 12-Meter", he illustrates a pivoting crane. The purpose is to distribute some of the load of the backstay into the mast and jenny struts, to keep the mast straight as tension is applied.
Has anyone experimented with this and would like to share experiences. I have been using it for a few years. Am I alone? are there any other tinkerer's out there?
