Am I a steel boat anchor?

Ok, I get it. Dyneema is morbidly static and breaks when you tie a blob of metal on it and factor-2 on three feet of it. |

It'll hurt like hell, but you won't explode your anchor. |

I'm not the same as a boat anchor. So my question is... do we know if a nylon PAS versus a dyneema PAS really matters when they're tied to a floppy human being? Has anybody factor-2'd a crash test dummy in a harness to see what happens?I posted a test of a smaller FF with regard to the exact scenario you spoke of. It's on this forum. |

Has anybody factor-2'd a crash test dummy in a harness to see what happens?We know how much flex (squashiness) there is in the human body in a harness because it has been tested and then we use a weight adjusted to compensate, it´s been done that way since the late 60´s. The technical term is surrogate testing. In real life we know that falling onto two quickdraws will break the karabiners and you hit the ground, Edelrid re-enacted that particular incident and came up with 27kN if I remember rightly. Otherwise why don´t you just try for yourself, learning by doing! |

That being said...I field tested this once by accident (yes stupid). Not actually factor 2 prob like 1.5. Hurt like hell but I'm still here. |

People fall on dyneema daisies occasionally while aid climbing, which is a pretty similar situation. Sometimes they break, but if they don't it'll definitely hurt and you'll probably injure your ribs. |
