Capsize shackle
The capsize shackle or patent shackle is a special shackle that is inserted into an anchor chain and serves to be able to separate the chain at this point if necessary. This shackle design is named after its inventor, the naval architect Max Kenter (* 1871, † 1921), who designed the shackle between 1905 and 1907 during his service at the Reichsmarineamt .

The capsize shackle is similar in shape to the normal links of the anchor chain ; it is only slightly thicker than her. It consists of four parts. Two of them form two halves of the chain link oval, which are designed in such a way that they interlock positively when they are joined together. The bridge is fitted in between. The three parts are fixed with a taper pin . To secure the taper pin against falling out and protect it against corrosion, the taper pin bore is tightly sealed with a lead seal hammered into it.
The advantage of this construction is that the capsize shackle adapts better to the chain sprocket on the anchor winch than the shackle shape previously used for anchor chains. Capsize shackles are inserted into the chain at intervals of one chain length . They are specially marked in color. When throwing anchor, for example, four shackles are reported to the bridge. This means that four chain lengths are launched. If necessary, the capsize shackle can be disassembled again with the help of the maker and bolt driver.
