    The only thing i would add is how you did the half hitches on your lashing, to make it stronger its advised to only do the half hitch on the last lashing line, not the bundle, that allows the lashing to settle correctly and put the tension across all the strands. Binding all the strands can put more load on a single strand if the lashing cannot settle out. Also its advised to use a max of 8 lashing strands. Great video as always.

    I replaced my stainless with Dyneema two years ago and all looking good. I spliced an eye at the bow end and used a cow hitch to attach. At the stern I spliced a low friction ring and then used Dyneema lashing, doing away with the turnbuckles. Andy UK

    As you mentioned at the beginning, use the SELMA Fids to improve your splicing skills a lot.
    In my opinion the SELMA Fids in combination with D-Splicer needles are the best tools you can get for this kind of work.

  • @bfett68

    Great video! The only thing that lifeline supposed to transfer load (a sailor going overboard) to strongest end-points (pushpit/pullpit). A knot in the middle will prevent it and deposit half of the load onto the stanchion.

    • @atomvoyager
      @atomvoyager  3 года назад +2

      Thanks for the comment. My idea is the knot is acting as a gate eye and in this case is no different than how standard lifelines work. Normal gates are just stanchions that are reinforced with a strut to be better able to handle the load so it's true that is a potential weakness since the stanchion is easier to bend without a strut. The only thing that will happen in this case is the stanchion initially takes some of the load and it bends very slightly until the load transfers to the pushpit. That won't be a problem or change the outcome of a sailor going overboard. The lifeline will still hold and do its job as far as I can tell. Small boats can't afford the space or justify bulky lifeline gates. Some owners forego the gate and have to clamber over the lifelines but I prefer having this poor mans gate to make boarding easier.

    Thank you! Wonderful tutorial! Would adding another pelican hook or small shackle to the pulpit be an option instead of the lashing? Guess the question should be...Why use lashing on the pulpit? Thank you!

    • @atomvoyager
      @atomvoyager  2 года назад +3

      Two more pelican hooks adds considerable cost and reduces the allowance for adjustment. If you need a quick release forward, for example because it would be easier to pull up a dinghy, then yes you could use the pelican hooks. The shackle is cheaper but won't work as well because you can't reattach it under tension and you have no adjustment. If you hoist the dinghy on a halyard then you don't really need to release the lifelines anyway. Just hoist it a little higher. It's not easy to measure and splice an exact length so the lashing guarantees the fit even if you miscalculate and it comes out an inch or two too short or long..

    25:20] Question, why do you never see a thimble used in the eye spliced at the end for all of the lashings to pass through? Granted dyneema is very slick stuff, and strong, this just seems like a situation where one might ordinarily think to use a thimble in an eye.

    • @atomvoyager
      @atomvoyager  2 года назад

      Some people use thimbles. I didn't because they are bulky and ugly and the low friction ones are pricey and not required for the light load relative to rope diameter even with occasional heavy loads from a fall. I only use thimbles for very high load areas like standing rigging and I might use the expensive ones that separate the lashings if I need less friction.

    The coated ones are only unsafe if you do not do proper maintenance and inspection . mine are from 1994 and no rust I clean inspect and remove them during the winter Thou i do like your dyneema lines and if I ever replace will go that route

    • @atomvoyager
      @atomvoyager  3 года назад +2

      Thanks for mentioning that. I had a poor choice of words. What I should have said was that since many coated wires were made with 304 wire and that you can't see through the plastic to see if the wire is cracked that they are a less safe choice than 316 grade bare 1x19. If yours have seen a lot of saltwater over the years and are not weeping rust then yours are probably made of a good grade of wire.

    Why the knots at the stanchions? I was under the impression we want the line to run through them to distribute the load across the stanchions. Am I wrong?

    • @atomvoyager

      The knot is acting as a gate eye and in this case is no different than how standard lifelines work. Normal gates are just stanchions that are reinforced with a strut to be better able to handle the load. It's true that is a theoretical weakness since the stanchion is easier to bend without a strut but in practice it should not be an issue. The only thing that will happen in this case is the stanchion initially takes some of the load and under high shock load bends very slightly until the load transfers to the pushpit. That won't be a problem or change the outcome of a sailor going overboard. You can keep the knot about an inch aft of the stanchion if you want to ensure the load is transferred to the pushpit and does not first load the stanchion. Small boats can't afford the space or justify bulky lifeline gates.

    Interesting to see you change from 316SS/1x19 wire lifelines to dyneema. Will you also be a convert to dyneema standing rigging with other parts from Colligo? Cutting the dyneema with Titanium shears is also very easy, as shown by YT Sailing Zingaro...Always appreciate your videos. Thought I'd have an A30 by now, but colon/liver cancer has slowed me, temporarily...

    • @atomvoyager
      @atomvoyager  3 года назад

      I do plan on using dyneema for replacing my intermediate aft shrouds on Atom soon but probably will stick with stainless 1x19 for the other standing rigging for now since I like my rigging to be set it and forget it rather than tensioning frequently for stretch and the other issues of changing to dyneema such as initial cost, bulky splices and fittings I don't care for the look of, UV degradation, etc. But I may come around to it one day as I get more familiar working with it. Sorry to hear about your health issues and I hope you find your boat soon.
