It is the anchor chain.
The turning radius of a vessel is a mathematical computation used to determine the turning circle of the vessel during anchoring in order to check if the anchor is dragging. It can be computed by adding the length of the anchor chain to the overall length of the vessel and subtracting the length between bridge and aft.
The swing circle is calculated by determining the distance from the center of the vessel's anchor to the outermost point of the vessel's bow or stern when at anchor. This distance is typically measured by adding the length of the vessel to the length of the anchor rode (the chain or line connecting the anchor to the vessel). The swing circle represents the area in which the vessel may drift while at anchor, helping navigators to avoid collisions with other vessels or obstacles. It’s essential to account for tidal changes and wind effects when assessing the swing circle.
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.
The length of chain between the shackles of a ships anchor chain is 90 feet.
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.
Anchor handling involves several key procedures to ensure safe and effective deployment and retrieval of the anchor. First, the vessel approaches the anchoring location, and the crew prepares the anchor and associated equipment, such as the anchor chain or rope. The anchor is then lowered to the seabed, allowing the vessel to drift back to ensure proper positioning. Finally, once the anchor is set and holding, the vessel's position is monitored, and adjustments are made as necessary to maintain stability and security.
The maximum cable length for a ship anchor, often referred to as the anchor chain or rode, typically ranges from 5 to 10 times the water depth in calm conditions. However, in rough seas or poor holding conditions, this ratio may increase to 10 to 15 times the depth. The total length can vary depending on the vessel size and type, but many ships carry several hundred meters of chain for safety and stability.
An anchor is a heavy object from a ship attached to along length of chain to hold the ship in one place.
the length should be 8 times the depth of the deepest water you are planning to anchor in.
The cable attached to an anchor is typically referred to as the "anchor line" or "anchor rode." This line can be made of various materials, such as rope or chain, and is used to connect the anchor to the vessel, allowing for secure anchoring in the water. The choice of material and type can depend on factors like the weight of the vessel and the seabed conditions.
"Anchor gypsy" is a term usually associated with boating and refers to a type of anchor chain arrangement that helps to secure the boat in place. It consists of a length of chain attached to the anchor to provide weight and stability. The chain is often stored in a locker or compartment called a gypsy on the boat.
