Don't use knots with dyneema line

Don’t use knots with dyneema line. Dyneema is very slippery and it is difficult to make a good knot that won’t slip with it. In addition the sharp-turns of the knots, will significantly reduce the strength of dyneema line. Ino-Rope recently conducted a test measuring the holding power of dyneema line with some common knots and am eye splice. The results were:

  • round turn and two half hitches – the knot slips with tension of around 125 kg
  • bowline – the knot slips with a tension of around 200kg
  • eye splice – no slippage, the line breaks with a tension of around 1.5 tons

This advice also applies to spectra line.
