If you’ve ever wondered what a lashing capacity is, wonder no more! A lashing capacity is the amount of force that can be applied to an object before it breaks.

In other words, it’s the amount of force you can apply to something without breaking it. The lashing capacity of an object is determined by its material properties, such as its tensile strength and ductility.

So, now you know! And knowing is half the battle.

In shipping, a lashing capacity is the maximum load that a particular type of lashing can safely secure. This includes both the weight of the cargo and the pressure exerted by weather or rough seas. Lashing capacities are regulated by international standards to ensure the safety of both maritime workers and passengers.

The benefits of having a lashing capacity

Most yachts have a lashing capacity which refers to the amount of pressure that the yacht can take before it begins to show signs of wear. This is an important factor to consider when choosing a yacht, as it will determine how long the yacht will last and how much wear and tear it can take. A lashing capacity is typically measured in tons or kilotons, and is a good indicator of the overall strength of the yacht.

The importance of having a lashing capacity

Lashing capacity is the amount of force that a particular lashing arrangement can withstand without breaking. It is an important consideration when determining which lashings to use for a particular load, as well as when designing a new lashing arrangement.

There are three primary factors that affect lashing capacity:

  1. The strength of the lashing material
  2. The type of knot used
  3. The angle at which the lashing is applied

The strength of the lashing material is relatively easy to determine; most manufacturers will provide this information on their product packaging or in their product literature. The type of knot used is also a major factor in lashing capacity; some knots are significantly stronger than others. Finally, the angle at which the lashing is applied also plays a role; generally speaking, the greater the angle, the greater the lashing capacity.

How to calculate your lashing capacity

To calculate your lashing capacity, you need to know two things: the SWL of your tie down and the WLL of your ratchet.

The SWL (Safe Working Load) is the maximum working load that a tie down can withstand without breaking. This is usually printed on the tie down itself.

The WLL (Working Load Limit) is the maximum working load that a ratchet can handle without breaking. This is usually printed on the ratchet itself.

To calculate your lashing capacity, simply divide the SWL of your tie down by the WLL of your ratchet. For example, if you have a tie down with an SWL of 1,000 lbs and a ratchet with a WLL of 500 lbs, your lashing capacity would be 2,000 lbs.

Your lashing capacity is the maximum amount of force that your rigging can take before it fails. To calculate your lashing capacity, you need to know the breaking strength of your rigging (BSL) and the safety factor (SF). The BSL is usually printed on the label of your rigging gear, and the safety factor is typically between 2 and 12. To calculate your lashing capacity, simply multiply your BSL by your SF.

For example, let’s say you have a rope with a BSL of 15kN and a safety factor of 2. Your lashing capacity would be 30kN (15×2).

It’s important to always use your lashing capacity as a guide, and not to exceed it. Doing so could result in serious injury or death.

Tips for improving your lashing capacity


Whether you are looking to improve your lashing capacity for work or for your personal life, there are a few things you can do to make it happen.

First and foremost, focus on your form. This means keeping a straight back and avoiding any hunching over as you lash. You should also be standing with your feet shoulder-width apart, which will give you a more solid base to work from.

Next, focus on your breath. Take deep breaths in through your nose and out through your mouth as you lash. This will help to prevent any dizziness or lightheadedness that can come from holding your breath while working.

Finally, make sure that you are using the proper tools for the job. The best way to improve your lashing capacity is to use a quality lash serum or protector that will help to keep your lashes healthy and strong.

FAQs about lashing capacity

  1. What is lashing capacity?

Lashing capacity is the maximum weight that can be safely secured by a tie down or lashing.

  1. How is lashing capacity determined?

Lashing capacity is determined by a number of factors, including the type of material used, the thickness of the material, the width of the webbing, and the number of layers of webbing used.

  1. How do I know if my load requires a higher lashing capacity?

If you are unsure whether your load requires a higher lashing capacity, it is always best to consult with a professional who can help you determine the best way to secure your load.
