The dark gray block housing the sheave for the jib halyard and the hardware to which the forestay connects to on my charleston mast is loose. I cannot determine if this is a safety hazard or not. Basically it got stressed when we connected the other end of the forestay and could not see that the mast end of the forestay was pointed straight out because the fitting stuck straight out like the sidestays turnbuckles do when you raise the mast. Is this going to fail? How can it be serviced? Thank you
