  • High-Performance LCP Fiber Rope:Longlines are fabricated using Vectran® LCP (liquid crystal polymer) synthetic fiber yarns to provide greater heat resistance as compared to HMPE fiber ropes. Super strong and ultra light, the ropes are treated with a polyurethane coating to resist abrasion and UV degradation.
  • Heavy Duty Nylon Covers:Protects the rope structure from dirt, grit, and grime while deterring UV light degradation. Made from 1000d Cordura. Uses heavy duty YKK® #10c marine-grade zippers.
  • Durable Construction:Fabricated with stainless steel thimbles and welded keeper rings to reduce potential thimble/rope disengagement. Wear pads at the connection point provide increased longevity.
  • Hand-Spliced Rope:Splice terminations feature lock stitch and whip lock and are individually proof tested to confirm structural integrity.
  • Color-Coordinated for Accurate Installation:Y-rope lines are color-coded and imprinted with block-lettered identifying text to ensure correct installation every time.
  • Ultra-Durable Laser ID Tags:Labels are impervious to rot and mildew to last the life of the rope.
  • Custom Sizes Available:HEC longlines can be ordered in custom lengths. Contact us for more information.



Hardware Notes

  • A Personnel Carrying Device System (PCDS) harness, as well as equipment to allow direct communication among required crewmembers and external occupants, must be approved by the local aviation authority. These are not available from Onboard Systems.
