Polyester vs. Nylon Webbing Awareness:
Manu Kea Inc., unlike many commercial manufacturers of jacklines, uses a polyester webbing. There are many reasons why we have chosen to use polyester and not the more common nylon (nylon is also commonly known as polyamide) webbing.
First, polyester does not absorb water like nylon. Nylon is known as a hydrophilic material and will absorb up to 10-20% of water by weight. When this occurs, nylon logically becomes heavier, stretches more readily and becomes noticeably weaker in overall strength.
Second, polyester does not stretch like nylon. When a heavy load is exerted onto a nylon material (such as webbing) it can stretch upwards of 10-14% (whereas polyester will only stretch between 1-3%). That 10% might not sound important however, if your jackline is 38-feet long (and experiences a heavy loading situation) that means the nylon jackline might conservatively stretch upwards of 3-feet 10-inches. As an example, if a sailor were to be lifted by a large wave while transiting the narrow side decks of a boat, the sailor could be moved 3-feet 10-inches outboard. And that same sailor might find themselves still attached to the jackline, but not necessarily still on the deck of the boat…
Lastly, we source webbing made in the USA with an astonishing 9,800-lb. minimum breaking strength. This is the strongest 1” webbing we can currently identify. Compare that with many so-called commercially available jacklines that only have a breaking strength of between 2,000 – 5,000-lb. Also all of our webbing comes with an engineered edge guard to prevent the onset of chafe.
Note: The percentages listed above may vary by specific material characteristics. The values given are considered conservative, legal, averages for publicly published material data available.
