The Ultimate Guide to Anchor Chains: Types, Applications, and Maintenance
Anchor chains are essential components for marine vessels, ensuring stability and safety while moored. Understanding the various types, materials, and maintenance practices of anchor chains is crucial for every sailor and boat owner. This guide will provide in-depth insights into the world of anchor chains, helping you make informed decisions for your maritime needs.
| Type of Anchor Chain | Material | Grade | Applications | Strengths | Limitations |
|---|---|---|---|---|---|
| High-Test | Galvanized Steel | Grade 40 | Cruising, commercial vessels | High strength-to-weight ratio | Can be expensive |
| BBB (Triple B) | Low Carbon Steel | Grade 30 | Recreational boats | Economical, widely available | Lower working load compared to HT |
| Proof Coil | Low Carbon Steel | Grade 30 | Basic anchoring needs | Cost-effective | Not calibrated for windlass use |
| Stainless Steel | Stainless Steel | Various | Corrosive environments | Superior corrosion resistance | Pricier than galvanized options |
| Stud-Link | Alloy Steel | Various | Heavy-duty anchoring | Very strong and durable | More complex to handle |
| Open-Link | Alloy Steel | Various | Flexible anchoring solutions | Easy to use and adjust | Less strength compared to stud-link |
Understanding Anchor Chains
Anchor chains are heavy-duty chains that connect a vessel’s anchor to its hull, providing the necessary weight and strength to hold it in place. Unlike ropes, which can stretch and weaken, anchor chains are designed to endure the harsh marine environment, making them essential for safe anchoring.
Types of Anchor Chains
Different types of anchor chains serve various applications and conditions. Here’s a closer look at some of the most commonly used types:
-
High-Test (Grade 40) Chains:
These chains are made of heat-treated, high-carbon steel, offering a high strength-to-weight ratio. They are popular among cruising sailors and are compatible with most windlasses. -
BBB (Triple B) Chains:
Made from low-carbon steel, BBB chains are economical and widely used for recreational boating. However, they have a lower working load limit compared to high-test chains. -
Proof Coil Chains:
Also made from low-carbon steel, proof coil chains are primarily for basic anchoring. They are not calibrated for windlass use, which can lead to complications if used improperly. -
Stainless Steel Chains:
Known for their superior corrosion resistance, stainless steel chains are ideal for saltwater environments. They tend to be pricier but offer long-term durability. -
Stud-Link Chains:
These chains feature oval-shaped links that provide increased strength and durability, making them suitable for heavy-duty anchoring applications. -
Open-Link Chains:
Flexible and easy to use, open-link chains are ideal for various anchoring solutions. However, they may not be as strong as stud-link chains.
Materials Used in Anchor Chains
Anchor chains are typically constructed from several materials, each offering unique advantages:
-
Galvanized Steel: Commonly used due to its resistance to corrosion. Ideal for recreational boats in saltwater environments.
-
Stainless Steel: Offers the best corrosion resistance but is more expensive. Suitable for long-term use in harsh conditions.
-
Alloy Steel: Often used for stud-link and open-link chains, providing a balance between strength and flexibility.
Maintenance and Care for Anchor Chains
Proper maintenance is essential for ensuring the longevity and performance of your anchor chain. Here are some key practices:
-
Cleaning: Regularly clean your anchor chain with fresh water and mild detergent to prevent corrosion. Inspect for rust or damage and address it promptly.
-
Storage: Store your anchor chain in a dry environment to avoid corrosion. High humidity can lead to rapid deterioration.
-
Inspection: Regularly inspect your chain for wear and tear. Any signs of rust, bent links, or weak spots should be addressed immediately by replacing damaged components.
-
Lubrication: Periodically lubricate the chain to prevent rust and facilitate smoother operation.

FAQ
What is an anchor chain?
An anchor chain is a heavy-duty chain that connects a vessel’s anchor to its hull, providing the necessary weight and strength to hold it in place while moored.
What are the types of anchor chains?
Common types include high-test chains, BBB chains, proof coil chains, stainless steel chains, stud-link chains, and open-link chains. Each serves different applications and has unique properties.
How do I choose the right anchor chain for my boat?
Consider factors such as the size and weight of your vessel, the conditions in which you will be anchoring, and the specific requirements of your windlass.
What material is best for anchor chains?
Galvanized steel is popular for corrosion resistance, while stainless steel offers superior durability. The choice depends on your specific needs and budget.
How often should I inspect my anchor chain?
Regular inspections are recommended, especially before long trips. Look for signs of wear, rust, or damage, and address any issues promptly.
Can I use proof coil chains with a windlass?
No, proof coil chains are not calibrated for windlass use and can cause operational issues.
What maintenance does an anchor chain require?
Routine cleaning, proper storage, regular inspections, and occasional lubrication are essential for maintaining the integrity of your anchor chain.
Why is the strength-to-weight ratio important?
A high strength-to-weight ratio allows for more efficient anchoring and easier handling, enabling you to store more chain in a limited space.
What happens if I use the wrong type of anchor chain?
Using the wrong type can lead to inadequate holding power, potential safety hazards, or equipment failure, especially if the chain is not calibrated for your windlass.
