Product details
Please note that this anchor chain is only available from a minimum length of 50 m!
If the base is already superlative
The anchor chain for discerning boaters with respectable performance characteristics.This anchor chain is made of high-strength special steel and then hot-dip galvanised. It ensures a tensile strength of 70 kg / mm² and offers twice the breaking load compared to conventional chains with the same weight. The carrying capacity and loads are comparable to those of lifting chains.
1: Grade 7, 2: Grade 4, 3: Grade 3
In the diagram, the breaking load of grade 7 is shown
(the example given concerns chains with a diameter of 8 mm and a breaking load of more than 7000 kg)
in contrast to the breaking loads of grade 3 and grade 4.
The technology
This anchor chain is made by experts with a know-how for products that exceed usual market standards, with greater reliability and performance. The chain is not only limited to statutory requirements for calibrated anchor chains (grade 3), but goes even further, with increased mechanical performance. With a breaking strength of grade 70, it achieves a strength that far exceeds normal standards.
A longer chain but the same weight
The higher breaking load of this chain means that a smaller diameter provides the same mechanical resistance as a conventional chain with a larger diameter. This means that it is possible to choose a much longer chain, without increasing the weight in the chain locker.
Comparison of chain length with same weight:
| Diameter (grade 3 chain) | Length (grade 3 chain) | Diameter (grade 7 chain) | Achievable length (grade 7) |
| 10 mm | 100 m | 8 mm | 160 m |
| 12 mm | 100 m | 10 mm | 140 m |
| 13 mm | 100 m | 10 mm | 170 m |
| 13 mm | 100 m | 12 mm | 120 m |
| 14 mm | 100 m | 12 mm | 130 m |
| 14 mm | 100 m | 13 mm | 115 m |
| 16 mm | 100 m | 14 mm | 135 m |
Are you looking for a lighter chain?
Do you have too much weight at the bow and want to make the ship lighter while maintaining the resistance of the chain and the length of the chain ends? This anchor chain is the solution!
Comparison of weight with the same length:
| Length of the chain cord | Diameter (grade 3 chain) | Weight (grade 3 chain) | Diameter (grade 7 chain) | Weight (grade 7 chain) |
| 100 m | 10 mm | 230 kg | 8 mm | 140 kg |
| 100 m | 12 mm | 330 kg | 10 mm | 230 kg |
| 100 m | 13 mm | 390 kg | 10 mm | 230 kg |
| 100 m | 13 mm | 390 kg | 12 mm | 330 kg |
| 100 m | 14 mm | 440 kg | 12 mm | 330 kg |
| 100 m | 14 mm | 440 kg | 13 mm | 390 kg |
| 100 m | 16 mm | 610 kg | 14 mm | 440 kg |
Are you looking for a less voluminous chain?
Do you want to reduce the volume of the chain, while keeping the same length and resistance? You can with the grade 7 chain.
Comparison:
| Length of the chain cord | Diameter (grade 3 chain) | Volume (grade 3 chain) | Diameter (grade 7 chain) | Weight (grade 7 chain) |
| 100 m | 10 mm | 86 dm³ | 8 mm | 50 dm³ |
| 100 m | 12 mm | 120 dm³ | 10 mm | 86 dm³ |
| 100 m | 13 mm | 150 dm³ | 10 mm | 86 dm³ |
| 100 m | 13 mm | 150 dm³ | 12 mm | 120 dm³ |
| 100 m | 14 mm | 172 dm³ | 12 mm | 120 dm³ |
| 100 m | 14 mm | 172 dm³ | 13 mm | 150 dm³ |

Technical question
Hi!
I’d like to buy 8 mm high stregth anchor chain 22902. I have a Lewmar Concept 1 windlass (1999). Its specifications are 8 mm DIN 766 / ISO. My present chain measurements are 8x22(or 23)x24 mm (d x t x b). Your chain is 8 x 24 x 26 mm. Do You think the 22902 chain works for my windlass?
