In all the confusion of dressing the mast and trying to get out of Savannah after our brief refit, I attached a block to the tang for the staysail halyard that I was not sure belonged. The block is a single Shaefer Marine (7 series I think) that does not swivel on the tang. The tang itself is welded to the mast. The halyard moves freely up and down and in line with the stay. I just wonder if it would be better to have the block swivel to reduce stress on the tang and the mast. Any input would be greatly appreciated.
