source of High strength 25mm polyester webbing for Jackstays?

[BrendanChandler]

used wire once - never again . Any thing as hard as that will be really dangerous as the wire core will allow the thing to roll even with the outer covering
Rope flattens better so why bother with the wire???

I agree 100%.
Wire is round and it rolls, inside or outside a casing.
When a jackstay is needed, it is because one's body is being thrown by great forces and those forces roll wire making one less stable and more likely to fall. (in my humble opinion but based on many thousands of miles on many boats),

Wire is unaffected by UV degradation.

But modern braid on braid takes years to degrade to a point where it cannot be used. I take mine off each winter so do not get winter degredation. the only noticeable difference is the fading of the flourescent orange colour chosen to stand out as a safety line

Much cheaper and readily available at most climbing/mountaineering shops. Just use a figure of eight knot at each end and no stitching to worry about with UV degradation.

I think you have missed something out ..... ?

Are you REALLY, REALLY, sure about that?

I replace all my slings every two years because of UV, remind me never, ever to climb with you.

You will never see a long distance boat with polyester jack stays, the only use on a boat is towing a dinghy because it floats. Use flat nylon webbing and as said with Dabond UV resistant thread. If you have never made them get a rigger to make them. Along with the harness and tether they are the most important bit of safety kit on the boat.

Intrigued..

So where would you find 25mm nylon webbing with 3000kg breaking strain?

As an example, the Marlow nylon webbing is only 750kg rated..

.. although that question might be a little late, since the OP has already ordered some from Cygnus Sails.. and I am about to do the same...

+1 for Jimmy Green. I bought mine from there, made to measure and with loops sewn in.

Which reminds me. They are 17 years old and perhaps ought to be replaced, although they appear fine and have been stored away every winter.

Its quite possible the webbing will look fine but the 17 year old stitching is not something to depend on when you need the jackstay in an emergency, time for new ones...

That's sufficient if you have a long and short tether, which is recommended for long distance sailing. If you use the short tether while moving on your knees forward or aft in bad weather then you can't go over the side which is where the heavy loads come in.

Yes - I'm sure you're right. I will order some replacements.

Great thread about jacklines, webbing, sewing and knots.

Agree about the short tether.. although the single 1m tethers are a bit short and it's been a pain recently replacing standard tethers with ones that include overload indicators!

Unfortunately 750kg is not compliant for many of the racing regulations.. Even short cross channel races require
2000kg.. 3000 is obtainable in 25mm webbing.. and at £1.29/m it seems strange not to use it...

Just that it's more difficult with which to work - a point to bear in mind when your jackstay price escalates by more than the additional material cost.

I've just ordered 100m of 25mm 2,100Kg breaking strand blue polyester webbing from Absolute Industrial to make some new jackstays.
It's cost me £53 delivered
I only need about 20m to make 2 jackstays, so if anyone else wants to buy a length or two just let me know.

If you are going to make your own webbing jack-stays, then this article http://www.bethandevans.com/load.htm might be of use - look about 2/3 of the way through under "Sewing Webbing".

No connection with the authors (occasional contributors to these forums) other than as a grateful reader...
