Opis:
David Lienbenberg (@jumbosailing) does professional #sailing and shows us how to make an Amsteel loop with a chafe cover. He does three wraps with 1/8' Amsteel and we break it afterwards with surprising results. Eye to eye, 1/8' Amsteel breaks at 12.4kN or 2,787LBF so a triple wrapped loop should be 6x stronger in theory or 74.4kN or 16,725LBF minus some for 'nothing works perfect'. Because we pulled it 'fast', then it broke at 34.1kN or 7,666LBF when it should have been over 44kN or 10,000LBF. So David made another and sent it to me and I pulled it 'slowly' and we got 49.95kN or 11,228LBF before I had to reset it because it didn't break, then ironically partially broke at 41kN or 9,216LBF then fully at 36kN or 8,092LBF.
