A lashing made of high modulus polyethylene Dyneema® is a textile connection system which is lightweight, reliable, long-lasting and resistant.
With a lashing, you can do anything: replace block shackles, Jack line or even standing rigging turnbuckles.
A lashing must include between 2 and 6 runs for a good balance of the strands. If there are too many runs, it decreases the lashing’s resistance: The strands risk overlapping each other. When a strand “”crosses over””, the lashing is imbalanced and its resistance decreases considerably. The strands must always be perfectly parallel to guarantee equal tension.
Bear in mind that the number of runs must be calculated according to the working load of the fitting to be fixed. In the same way, the calculation of the lashing resistance must take into account the Dyneema® working load (tension for “normal use”) and not the breaking load (maximal tension before the braid breaks).
For “high load” lashings with a maximum of 6 runs, increase the resistance by choosing a larger diameter of Dyneema
