On vessel anchor chains, four different types of markings are commonly observed. The first type of marking is the name or emblem of the maker. This is frequently stamped on the links towards the chain's end. The grade or strength of the chain is the second form of marking. This is commonly indicated by a number or letter code that is stamped onto the chain's links towards the middle. The size of the chain is the third type of marking. This is commonly denoted by a measurement in inches or millimeters, which is stamped onto the chain's links near the beginning. The length of the chain is the fourth sort of marking. This is commonly denoted by a measurement in feet or meters, which is imprinted onto the chain's links at regular intervals along its length.
When you're out on the water, you could see a few distinct kinds of anchor chain insignia. The CE Mark, which stands for Conformité Européenne, is the most popular sort of labeling. This emblem signifies that the chain fulfills the European Union's basic safety requirements. Other frequent certification marks include ISO 9000, which indicates compliance with worldwide quality standards, and Lloyd's Register, a UK-based independent certification authority.
The anchor chain on your sailboat is one of the most crucial pieces of equipment on board. It is responsible for keeping your yacht grounded and secure in all weather and sea conditions. Maintaining your anchor chain properly is critical to ensuring its longevity and functionality.
Check your anchor chain on a regular basis for signs of wear or damage. If you find any damage, have it repaired or replaced as soon as possible.

Regularly lubricate your anchor chain with high-quality marine oil or lube. This will help to maintain it corrosion-free and working smoothly.
When not in use, properly store your anchor chain. Assemble it firmly and keep it in a cool, dry area away from direct sunlight.
There are numerous sorts of vessel anchor chain marks that can be perplexing to people who are unfamiliar with them. Here's a rundown of the most popular markings:
-Anchor Chain marks: These marks are often seen on the end of an anchor chain and identify the chain's size, grade, and length.
-Proof Coil Chain marks: These marks, which are normally placed on the side of the proof coil chain, show the chain's operating weight limit and grade.
-Stud Link Chain marks: These marks are often located on the side of stud link chains and show the chain's diameter, length, and grade.
Vessel anchor chain markings are essential for a variety of reasons. First, they aid in the identification of the vessel. Second, they aid in ensuring that the proper amount of chain is used. Third, they aid in determining the direction in which the vessel is anchored. Finally, they aid in providing information on the person in charge of mooring the vessel.
On vessel anchor chains, there are three types of markings: the manufacturer's name, the grade, and the size. The manufacturer's name is normally stamped onto the chain's links at the end, while the grade and size are typically stamped onto the swivel or shackle.
The breaking strength of an anchor chain, measured in kilo-newtons (kN), determines its grade. Grades 20, 30, 40, 50, and 60 are the most prevalent. The stronger the chain, the higher the grade.
Anchor chains are measured in inches or millimeters (mm). 3/8′′, 1/2′′, 5/8′′, and 3/4′′ are the most frequent sizes.
Always begin reading vessel anchor chain markings with the manufacturer's name. This will tell you who manufactured the chain and is useful if you need to acquire replacement parts. Check the grade stamp to ensure that the chain fulfills your strength requirements. Finally, double-check that the size stamp corresponds to the connections on your vessel's anchor road.
Different vessel anchor chain markings can be used to identify the chain's manufacturer, grade, and length. CE, ISO, US Coast Guard, and delta symbols are the most prevalent designations.
CE: Conformité Européenne (European conformity) is a voluntary label that indicates that a product satisfies the essential standards of all applicable European directives.
ISO: International Organization for Standardization is a global standards-setting organization whose norms are accepted around the world. ISO 9001 is the world's most well recognized quality management standard.
US Coast Guard: This symbol denotes that the chain has been certified by the US Coast Guard to fulfill its stringent quality and safety criteria. The delta symbol () next to the USCG designation indicates that the chain is constructed of a high-strength steel alloy and is suitable for maritime use.
The delta sign () indicates that a product meets or surpasses the requirements defined by an independent certifying authority such as Underwriters Laboratories (UL), British Standard Institution (BSI), or Intertek (ETL).
Understanding anchor chain marks is critical for determining an anchor chain's correct size, length, and strength. Knowing the grade, diameter, and number of links in a vessel's anchor chain will assist you in ensuring that your boat is securely secured and safe from storms or mishaps. With this information in hand, you should be able to select the appropriate size anchor chain for your boat.
