Guardrail Knot/ lashing

[muzzaman]

Does anyone have any suggestions as to a suitable knot to use to tie off my guardails to the pulpit/pushpit?

I have attached a very poor picture of the current one.

I thought a shackle at the Pulpit and a lashing at the stern/pushpit was best.

Basis is that you need to be able to cut the stern to get a MOB back??

Yes, I intend keeping the lashing at the stern end for that very reason. On the basis that the string used for the lashing is 3 years old I wanted to replace it in case of any UV deterioration.

 

[muzzaman]

If anyone can tell me the name of the lashing in the picture that would be great. I have searched already but no joy yet!

Many thanks.

It's just a load of half hitches around the looped cord, nothing complex. Get a piece of cors of 1m or so and tie it off to either the pushpit or the wire loop. Next, make several loops going through both - this gives you a bit of leverage to tighten very much like using blocks. Then wrap the cord around the loops and tie a half hitch. Do this until you run out of cord or reach the end then cut and tidy.
Cheers

Thanks Dave. Just the info I was looking for.

here are some instructions for a little more sophisticated lashing.

Its best if you either sew or tape the end of the tail to the main lashing, so it does not have any tendency to loosen/unwrap.

My 2d-worth is to use red braid-on-braid line for the lashing- it deteriorates fastest in the sun and when it discolours it's a good time to replace. The jacket degrades well before the core, which is the most important part anyway... It won't lose any strength as the cover degrades, because the load-carrying parts are buried under the locking-hitches anyway...

 

[lustyd]

Do they make braid on braid that thin? I love the idea but I only used 3 mm line.

Caterpillar knot

I always knew it as a caterpillar knot, You have a choice when you do it of changing direction after every pass so that the knots line up or you can keep going around so that the knots circle the lashings. Definitely worth doing the caterpillar knot though.

I plan to use SS pelican hooks instead of line with the ring sliding over the hook under pressure so can'y be undone accidently :

You'll screw up your DF radio positioning if you do!

The surveyor who checked my new boat was squarely against lashing the guardrail. In fact he questioned the wisdom and the safety of working on a sidedeck in what are likely to be very difficult circumstances without effective guardrails. No point in losing more people over the side.
Worth a thought imho.

How, then, did he propose rolling an MOB back aboard?

Agree also take your 3mm line braking strain 150kg or 4mm Line 320kg give or take... Wrap it through so you have 6+ Strands supporting it= 900kg or 1920 kg Breaking strain?

I think something else would break before your little bit of line? Seems over the top to me.

I would consider fitting Senthouse slips/ Pelican hooks or similar as very useful to be able to drop rails to lift gear bags etc onboard. Just need to make sure they are not going to come undone when you do not want them to: mousing, lashing, tape, cable tie, elastic loop, etc.

When lashing up the guardwires I always put a few half-hitches partway through tying the whole knot. That way, if one strand should get cut through, the whole knot doesn't unravel in one go.

That pelican hook wont work

There is no way you could ever get the guardrail accurate enough to use this hook as there is no adjustment. I would always go with the lashings as rigging screws to tighten always age rapidly due to articulation issues.

You can get pelican hooks with adjustment but they would definitely need to be secured (presumably taping them would be only real solution). which makes the quick release appeal less appealing.

I also agree that the lashing is the strongest part of that system prob with pushpit / pulpit failing first, then wire, then lashing but if you make them too small they don't look right.


If your serious about getting MOB in in a hurry you could put gates in amidships but then thats a whole can of worms .......

I think this type is more secure:

Yes there is a way. A small 10mm size bottle screw with forks terminals inserted between the guardrail wire and pull pit shackle. It is then adjusted to keep sufficient tension on the pelican Hook at the stern. Its a common method of tensioning guard rail wires. I don't think I have ever seen rapid ageing of a rigging screw.

Pelican Hooks are designed to stay shut when under tension. My liferaft is secured by a webbing strap attached to the deck with a Pelican Hook. This arrangement has never come undone, is a very common arrangement and in fact, due to the tension in the webbing it takes quite a bit of force to slide the lock ring over the end of the Pelican Hook.

I would agree if the guard rail wire is slack that the Pelican Hook could come undone quite easily, even accidentally, however, a shock cord loop would easily keep the Pelican Hook lock ring in the correct position.

Why do you think gates are a can of worms. Just about all yachts I have sailed on have some form of gate in the guardrails. They all functioned well and didn't appear to be any hassle at all.

Under the guard wire, through the gate or via the swimming platform. All will depend on circumstances, I imagine.
My first and second priorities will always be to keep everybody safely on board.
