The number of shackles in an anchor chain can vary depending on the size of the vessel and its operational requirements. Typically, a standard shackle in an anchor chain measures about 15 fathoms (90 feet or 27.4 meters). Most ships carry anywhere from a few to several dozen shackles of chain to ensure they have enough scope for anchoring in different depths. It’s important for vessels to have adequate chain length to maintain stability and safety while at anchor.
The length of chain between the shackles of a ships anchor chain is 90 feet.
To determine how many shackles of anchor chain are in the water, you first need to measure the length of the chain that is deployed. One shackle is typically 15 fathoms (or 90 feet). By dividing the total length of the chain in the water by 90 feet, you can calculate the number of shackles. For example, if 180 feet of chain is in the water, there are two shackles deployed.
There are several types of shackles, primarily categorized into three main types: anchor shackles, chain shackles, and bow shackles. Anchor shackles are typically used for connecting chains to anchors, chain shackles are designed for connecting chain links, and bow shackles have a wider body, allowing for multiple connections. Each type serves different purposes in rigging and lifting applications. Additionally, shackles can vary in size, material, and design based on their specific use cases.

An anchor shackle's length can vary widely depending on its type and size, but commonly used sizes range from about 3 inches to over 12 inches in length. The specific length is often determined by the application and the size of the anchor chain or rope it is designed to connect. Shackles are available in various configurations, including D-shackles and bow shackles, each with different dimensions suited for particular uses. Always refer to manufacturer specifications for precise measurements.
In most cases, people recognize bow shackles and anchor shackles as same, their names are used interchangeably. However, although the shape of bow shackle and anchor shackle looks similar, they are different type of shackles. Normally, the bowed part of bow shackle is much larger than an anchor shackle.

The length of anchor chain can vary depending on the specific type and manufacturer. However, a common size for anchor chain is 1 shot, which typically equals 15 fathoms or 90 feet. Therefore, 9 shots of anchor chain would be 9 times 90 feet, totaling 810 feet.

Another name for an anchor chain is a "cable." In nautical contexts, it may also be referred to as a "chain cable," which specifically denotes the heavy chain used to connect an anchor to a vessel.
A bow stopper is a fitting to secure the anchor chain or rode to the vessel's bow when the anchor is raised. A chain stopper is used to hold the anchor chain in place and relieve strain on the windlass when the anchor is deployed or retrieved.
