Crimps for lifelines; Copper vs Nickel Plated Copper?


Recommended Posts

What is the right crimp for the job? Copper or  Nickel Plated Copper?

Also, why are lifelines tensioned with the weird bit of lashing, rather than something like a turnbuckle / rigging screw? 

I assumed it was so you could cut it free? But the swages ends won't pass through a stanchion anyway so what does it gain you?

The rule is / used to be that cutting the cord would give you enough slack to help retrieve a MOB via the side-decks. This was a rule I remember affecting racing boats in the UK 20-30yrs ago and before open transoms were mainstream. No idea if still applicable today.

Both. It depends on what finish looks the most purdy in your eyes.

There is nothing stopping you using a rigging screw or similar tensioning item over lashing. Cheapest, easiest to adjust, removes less skin when fallen on to. We'd do 80% lashing, 20% something else. Now up to around 50 - 50 when looking at fibre verse wire.

I'd use webbing or a soft floppy dyneema, I'd never ever use wire or a hard heat set dyneema.

Stand on them all and you'll quickly learn why.

Interesting - its what the PO had - but it was raised about an 1/2 inch off the floor of the wooden lattice that runs along the floor of the cockpit so you would never really stand on it.

"Jackstays shall have a minimum strength of 2000kg.
Webbing that lies flat is recommended."

I would use dyneema, webbing doesn't seem to last to well.

OSR is a bit more explicit, technically you are required to meet this standard too, YNZ seem a bit lost on this though.

"have a breaking strength of 2040 kg (4500#) and be uncoated and nonsleeved stainless steel 1 x 19 wire of minimum diameter 5 mm (3/16”),webbing or HMPE rope"

If there is no hazard like standing on it leading to it rolling or a anything tripping then wire would be fine bar the fact it'll be a bit hard on everything it touches.

My go to is webbing. It lays flat, you can see when it's degrading and it's cheap to replace.

What the Safety Regs say is fine but when that wave smashes into you that book and whomever wrote it won't be the ones washed overboard. It's a handy guide to put into the mix but that's all.

Webbing. Mine has a couple nice reflective threads running the length of it...

unfortunately there’s still a shittonne of other lines to have roll under your feet.
