I concur
Mike B.,I agree. I had assumed that Mike was referring to the horizontal pin that links the gooseneck and boom. I assume that you are referring to the vertical keeper pin. Either way, I believe a compilation of our thoughts should fix the issue. I, like you, use an eye bolt and attach there for reefing. If, in fact, Mike is referring to the horizontal pin that links the gooseneck and boom, then my suggestion of cutting a stainless bolt, necessarily includes cutting off any threads and using only the smooth portion of the bolt.
