What is the first shot in an anchor chain called?

The first shot in an anchor chain is commonly referred to as the "swivel." This designation is important as the swivel acts as a connecting piece that allows the anchor chain to rotate freely. It facilitates the anchoring system by preventing torsional stress that could cause damage to the chain or anchor. Additionally, the swivel typically connects the anchor chain to the anchor itself, ensuring a secure and reliable attachment.

While terms like "danger shot" and "first shot" might seem relevant, they are not standard terminology used within naval operations to refer to the first link of the chain. The term "anchor shot" doesn't specifically designate the first link, which is why "swivel" is considered the correct term in the context of anchor chain nomenclature. Understanding this terminology is crucial for effective communication and maintenance of anchoring systems in maritime operations.
