Procedure on how to measure anchor chain size

The process of how to measure anchor chain size will be briefly discussed. We will talk about its details later in the article. Let’s begin.

 A caliper would use a tool like this. So that the diameter and pitch of the chain links can be accurately measured. Input these measurements into an online calculator or reference chart. In order to determine the appropriate chain size.

Will consider boat size, weight and anchoring conditions. So that the selected chain size can meet certain requirements. Correct measurement and selection of anchor chain size will contribute to safe and efficient anchoring practices. It will enhance the overall boating experience and safety.

The process of how to measure anchor chain size

How to measure anchor chain size will be concerned in detail. From here you can learn more about what kind of machine is required to calculate anchor chain size. With unique tips.

Step by Step Measurement Process


Measure the diameter of the chain links

A caliper or ruler should be utilized to measure the diameter accurately. First, create sure the chain link is straight and free of twistings. Then, set the jaws of the caliper about the widest part of the chain link. If attainable, use a ruler to calculate its diameter.

Will record measurements in millimeters or inches for exactness.

Determine the chain pitch

It will estimate the space between straight chain links. That’s why one would use a measuring tape to determine the space between the middles of two adjacent chain links. Will compute several links in a row for any changes. The chain will estimate the average distance to get the pitch.

Calculate the chain size


Using online calculators or reference charts. Measure chain links in online anchor chain size calculators. It will input the diameter and the calculated chain pitch.

Boat size and importance should be reckoned for appropriate chain height.

Follow your boat’s size and weight when choosing chain size. Because bigger boats or those revealed to rough conditions will require more serious and more effective anchor chains for safe anchoring.

Tools needed

Caliper or Ruler: A caliper is a unique calculating device. It is utilized to accurately estimate the diameter of chain links. A ruler can also be utilized for this purpose. 

Yet, it cannot produce precise measures like calipers. Setting the caliper jaws around the chain link. Or utilizing a ruler to estimate the diameter of the chain link. Always ensure measurements are accepted at the most complete point of the link for accuracy.

Measuring Tape: A measuring tape will be required for determining the space between successive chain links. It is apprehended as chain pitch. Will estimate the distance between each link. Then, stretch the measuring tape along the height of the chain. Make sure steps are taken accurately to choose chain pitch.

 Optional Anchor Chain Guide: An anchor chain guide is a unique tool. That is the specification of the boat. It will also guide for choosing the correct chain size established on anchoring conditions and other factors.

Tips and Considerations

Confirm proper standards for safety

  • Actual sizes of chain diameter and angle are essential in choosing the proper chain size.
  • Mismeasurement Improper anchoring, compromising safety and efficiency.
  • Allow a little more additional time to calculate carefully, delivering accuracy for reliable anchoring structure.

Manufacturer’s policies for specific advice

  • Plants often post anchor chain size guidelines for their effects.
  • Consult the factory’s approaches to best suit your anchor and ship.

Also, seek advice from boating specialists. Who will make personalized advice based on your boat’s specifications and intended use.

Considering environmental factors

  • Environmental factors, such as water depth, seabed type, and climate conditions, will impact anchor chain section.
  • Choosing a chain height that fits the desired anchoring needs to ensure good holding ability.

In conclusion

Utilizing the right anchor chain size will deliver safe anchoring. Contains the boat from sailing and improves safety. This will maximize the holding capacity and reduce the risk of anchor drag in adverse conditions.

Choosing the size will also contribute to the longevity of the devices and the general boating experience.

Frequent checks provide that anchor chains are in good shape and free from injury or decline. Follow plant’s policies for anchor and chain holding to prolong their life. Thank you for reading our articles How to measure anchor chain size. 


How to easily calculate anchor chain size?

Simple Equation The simplest equation is: Wind Speed ​​+ Boat Length = Chain Length. This will work for anchorages up to about 10 meters. Beyond that depth, 1.5 times the wind speed must be calculated instead.

What is the size of the anchor rope of a 20-foot boat?

 If you need one 1/8-inch-diameter anchor rod for every 9 feet of boat length. For example, if you have an 18-foot boat. Then you will need a 1/4-inch-diameter (2/8) line. Doing the math shows you need a 3/8-inch-diameter line for a 20-foot boat and 1/2-inch-diameter line for boats up to 36 feet

How will the anchor chain be marked and measured?

Measure your anchor chain using red, white and blue paint. Chain-red 25 feet 25 feet from the anchor. Then you can put one coat of color on each section marked white at 50 feet from the anchor, blue at 75 feet from the anchor and yellow/gold at 100 feet

What is the formula for anchor wire length?

A guideline is cable length plus 3 times the water depth under normal conditions. ie should be 90 meters. It requires 6 chains under normal conditions for a depth of 25 m. In rough weather, the cable length will be 4 times the water depth and 150 m.

How do you calculate anchor length for stiffness?

Lb, used for calculating bolt stiffness, is half the thickness of the nut. The thickness of the washer, tw, the thickness of the base plate, tbp, the thickness of the grout or gap, tg, and the length embedded in the concrete can be determined. 8d as expected where d is the bolt diameter
