3-3.5% elongation at break for Stealth. Dux website states: elongation is very low or about 3%.
Anyone have any thoughts about using Stealth for standing rigging?
There are several types of elongation. Creep is what Dfelsent has described (a slow, irreversible increase in length when a constant load is applied over a long period of time). This is different to elastic elongation
, which in this case is given as 3.5% at break load.
Looking at the Southern Ropes booklet, they vaguely state that creep has been “virtually eliminated” due to the process of thermofixation that incorporates “stretching under controlled temperatures with a precise continuous applied load”.
They do not, however, list standing rigging under “applications”.
The easiest thing to do is email
Southern Ropes and ask about the figures for creep and the suitability of Stealth Super 12 as standing rigging.
