Actually tdw it is the anchor shackle in that same spot. BTW, an anchor shackle is straight sided and stronger than a bow shackle. It stows in the hawse pipe much better also. While on the subject of shackles, it is a mystery to me why none of the yachting catalogs offer a true safety shackle. A safety shackle has a threaded pin that threads not into the shackle itself, but a nut on the outside of the shackle. The pin has a hole through which a cotter pin is run through. The shackle develops full strength as the pin is full diameter going through the shackle body. A Jew's Harp is such a shackle and it amazes me that all the shackles, "safety" or otherwise require mousing. Is there a reason for this?
