An integral attribute of every watercraft, be it a sea vessel or an inflatable PVC boat, is a deadlift anchor. Connected to the ship's hull by means of an anchor chain or rope, it reliably holds it in place from the effects of wind or current. For small vessels this important element is the anchor line, the choice of which should be approached taking into account certain requirements. Often ships are equipped with additional anchors, the weight of which is slightly less. They allow you to keep the craft in a more stable condition, but the requirements for the anchor lines remain unchanged.
The weight of the anchor, whether it is a simple folding cat anchor or a Danforth anchor with a holding force of two hundred times its own weight, is selected taking into account the displacement of the vessel. Obviously, this is one of the conditions that must be taken into account when choosing an anchor line. Additionally, it must cope with the loads caused by the sail of the vessel.
Let's consider some criteria that should be followed when choosing such an important element of equipment for a small vessel.
Types of Anchor Ropes
When selecting an anchor line, its following characteristics should be taken into account: strength, elasticity, diameter, length. These characteristics directly depend on the type of anchor rope, which is determined both by the material of manufacture and the production method.
According to the Material Used
One of the most important categories in the classification of anchor ropes is the material from which this product is made. Today, in the age of the triumph of high-strength polymers, the use of ropes and cables made from natural materials should not even be mentioned.
Today for the production of reliable anchor lines various synthetic materials are used.
- Polyester (PES) is a modern raw material that combines increased strength, low hygroscopicity, abrasion resistance and high specific gravity. When in contact with water, polyester ropes do not shrink or lose flexibility. Twisted polyester rope will serve you for many seasons.
- Polyamide (PA), or nylon, is practically not inferior to polyester in its strength characteristics. It is distinguished by elasticity and pronounced tensile strength. Polyamide ropes hold a knot well, are highly wear-resistant and resistant to UV radiation.
- Polypropylene (PP) is a medium-strength material with positive buoyancy. The rope does not absorb water and does not deform when wet, it is light in weight, and one of the most inexpensive. One disadvantage is insufficient resistance to UV radiation. If your field of activity is commercial fishing, you should prefer products made from light-stabilized polypropylene.
The unique strength characteristics, resistance to moisture and ultraviolet radiation of cords and ropes made from these materials allow them to be used as anchor and mooring cables.
By Manufacturing Method
When it comes to the way they are made, anchor lines can be twisted and braided, with or without sheaths, as well as without a core. For anchor lines both twisted and wicker models are used.
Braided anchor lines are made using the through weaving method - all its elements are very tightly intertwined. This design provides high strength and wear resistance. This rope, made of high-strength polyester, has good buoyancy, does not absorb moisture and is resistant to mechanical damage and aggressive environments.
Twisted anchor line is a multi-strand twisted rope. The main difference from braided rope is maximum strength, resistance to ultraviolet radiation and abrasion.
Twisted line made of polyester, polypropylene or polyamide is much stronger compared to braided rope with the same diameter. The higher the quality of the weaving, the smoother the cable and the more convenient it is to work with. Twisted rope stretches better and is less sensitive to abrasion.
Both types of cables are comparable in such an important parameter as elasticity, which allows them to withstand dynamic loads. True, here we have to look for a compromise option in order to avoid the “elastic band” effect with excessive lengthening of the cord.
By Diameter and Breaking Load
The diameter of the cable, as well as the material from which it is made, is interconnected with the strength characteristics - tensile load. But there are certain subtleties here too. For example, a nylon cord with a diameter of 4.0 mm is enough to hold any inflatable boat. But in practice, it should be taken into account that PVC boats usually do not have special equipment, and you have to select the anchor manually. A cord that is too thin might hurt your hands, so the optimal diameter would be a cable starting from 8.0 mm, with some margin of safety.
When choosing an anchor line’s length try to take into account the possible depths at which it can be used, usually 5-8 times higher. For small vessels it is usually 30-40 meters.
Like the mooring line, the anchor rope is selected taking into account the displacement of the craft . It is also important to take into account the windage of the vessel, which, due to the superstructures of boats and yachts, unlike small inflatable boats, is higher.
How to Choose an Anchor Line in 3 Steps
Let us repeat that anchor line is an important element of equipment for any vessel and is designed to hold and secure it in open water, including in windy weather or in currents. The safety of the vessel's anchorage depends on the correct choice of such a cable. What should you consider when choosing an anchor cable?
Step 1. First of all, you need to determine the appropriate diameter of the rope or cord. To do this, you need to know the length of the vessel and its weight. The diameter of the anchor cable directly depends on these parameters.
| Vessel length, m | 6-8 | 9 | 10 | 11 | 12 | 14 | 16 | 18 | 24 |
| Vessel weight, tons | 2 | 4 | 5 | 7 | 8 | 11 | 12 | 20 | 22 |
| Anchor rope, Ø mm | 8 | 10 | 12 | 14 | 16 | 18 | 20 | 22 | 24 |
Step 2. Next you need to decide on the length of the cable. For small vessels, it is calculated using the following formula: anchorage depth plus 3-5 ship hull lengths. In the event of strong winds, it may be necessary to remove additional amounts of cable so that the anchor lies completely on the bottom and provides good grip on the ground. When the anchor is in a vertical position, the vessel is less stable and there is a risk of it moving.
Step 3. Another important criterion when choosing an anchor cable is the type of its construction. Professionals recommend using twisted ropes for anchoring. Twisted products are characterized by a high degree of reliability, strength and abrasion resistance. The use of such cables will minimize the risk of anchor loss.
In addition, braided cords of specialized series with low elongation can also be used as an anchor cable. And in case of great depth, strong currents or wind, which increase the rocking of the vessel, it is recommended to use cables with a lead core or a chain at the end.
How to Store and Maintain an Anchor Cord
Proper care of the anchor cable extends its service life and ensures the reliability of the anchor system. First, let’s determine from what harmful effects the anchor lines should be protected.
Friction
Avoid contact with anchor line with abrasive surfaces, sharp edges, hard particles (for example sand). Rollers and pulleys must have smooth surfaces and rotate freely.
Do not allow the rope to bend sharply under load. The diameter of the minimum bend must be six times the diameter of the rope.
It is necessary to check areas of the rope that are subject to friction and regularly reposition the rope to ensure even wear.
Temperature
Operation (and storage) of the rope must occur within a certain temperature range, depending on the material. Working with a rope that is exposed to overheating or hypothermia significantly reduces its service life. In addition, all the main characteristics change, seriously reducing reliability and safety.
Heating can occur not only from external heat sources, but also as a result of friction. This is influenced by the magnitude of the load, the intensity of pulling, the smoothness of the contacting surface, the material and the design of the rope.
Ultraviolet Radiation
Sunlight has a negative effect on synthetic ropes. The speed of exposure depends on the material, type of weaving, light intensity and duration of exposure.
Chemical Exposure
The sensitivity of a rope to certain chemicals depends on the material. If aggressive chemicals are used on the yacht for washing and cleaning, if they come into contact with the anchor line may damage it.
Based on these dangers, a system of caring for anchors lines and their storage conditions has been developed.
- Check the anchor line for wear, damage and looping regularly.
- After use, rinse the anchor line with fresh water to remove salts, sand, barnacle build-up and algae. For cleaning anchor line, you can use special devices such as the cleaner of overgrown marine ropes. They will protect your hands and speed up the cleaning process.
- After washing and cleaning the anchor line should be dried thoroughly. Drying in sunlight is not recommended, even if the rope is made of UV-resistant polymer.
- Store anchor line in a dry, ventilated place to prevent mold formation. Again, do not rely on the resistance of polymers to rot; if poorly cared for, they can be affected by fungi, as well as germinated by sea and river flora.
FAQ
Why nylon is considered the best material for anchor ropes
Nylon, or polyamide (PA), is one of the most durable synthetic materials for marine equipment and accessories. It has the highest wear resistance and resistance to ultraviolet radiation. According to its physical and mechanical characteristics, it is an ideal choice for anchor lines.
What is the difference between an anchor rope and a regular rope?
Specialized anchor lines allow you to select a cable that meets your requirements in various parameters. All seafarers have different sailing practices. Some people need a sinking line, others need a floating line. The same applies to dynamic characteristics: some choose an elastic option, others choose a non-stretchy one. Conventional ropes do not offer such a wide range of characteristics.
How to avoid tangling and twisting of the anchor rope
The most reliable way to avoid tangling and twisting of the anchor rope is to use a vertical or horizontal anchor winch on the yacht, be it manual or, better yet, electric.
