What about the tight radius wrapping around the soft shackle? Surely this iscthe weak point of it? Care to repeat but use wraps at the other end for full strength so it's all but guaranteed to break in the complex end unless the weakest part of the complex end is stronger than the line itself in whuch case that would constitute proof tgat the arrangement is optimal.
He explained that at 3:47. By creating the shackle the line is doubled, then you wrap it round when connecting it which doubles it again, distributing the load over 4 strands rather than a single strand. So the weakness at the radius is only bearing approximately quarter of the load compared to the single line going into the bowline.
Amazing video with a lot of information. I just didn’t understand when you say an “extra hitch” on Bowline knot. Is it a double bowline (aka Water Bowline) or Yosemite Bowline? Thanks in advance.
Nice demo. How did you tie the diamond knot? Did you really pull 12 metres of halyard through each loop of the knot as you tied it? Or is there an easier way? Definitely going to try this on a boat that currently has a wire main halyard. It's always a pain to get that spliced joint between the wire halyard and the rope halyard tail through around the bottom pulley, and sooner or later it's going to break, ...or worse: jam when I need to drop the sail in a hurry. A single-piece halyard in Dyneema would be far preferable.
You can tie most of the knot which the short tail. But yes, you do have to pull through the halyard length on the last step. I am sure there is a way of tying it without doing that however! Maybe I should learn over lockdown?
@@MozzySails Just be careful not to use too high strength line - tow hitches aren't as strong as you might think. If the hitch fails the tow ball gets fired through the rear windscreen of the pulling car, potentially killing the driver. ua-cam.com/video/eFD4Fd03bq8/v-deo.html
I like the test. It would be interesting to see the same test with a scots lock bowline

Just a half hitch with the tail around the bowline loop
very cool demo and good explanations :)
Glad you liked it!
Great video, what is the advantage of using the diamond knot as opposed to splicing the soft shackle on?
It's just to avoid using a bobble. Where you need a stopper for hoist. The bobbles move around and punch the rope, and are a source of chafe.
Gareth Griffiths, I think that your goose is cooked.

Really interesting video. Please pull more things apart with cars in future videos!
Ha! I'll see what I can do!
