This video shows how to calculate the number of shackles to be dropped when dropping a ship's anchor. It includes determining the number of shackles that have been dropped by reading the markings on the anchor chain. The calculations are just a reference. There are other methods of calculations and you can use the method you are familiar with. A ship's anchor is a heavy device typically made of metal that is used to secure a vessel in place by gripping the seabed. Anchors are crucial maritime equipment for ships of all sizes, ranging from small boats to large ocean-going vessels. They are essential for various maritime operations, including anchoring in ports, harbors, and offshore locations, as well as during emergency situations or when conducting maintenance activities. #Anchorage #Anchor #Shackles #Calculation
