Any reason why not?
Go Outdoors are having a sale and 60m of 9.8mm "Perfect Sport Rope" is £89.
I am assuming the rope is good quality, and has good chafe properties, but perhaps a bit stretchy?

Also this: 50M of 10mm for £ 85.

More expensive per M. But still cheaper than 10mm Marlow braid, even from Jimmy Green.

Think I might pop down there later.

Not just a bit ...far far too stretchy!
 
"A bit stretchy" possibly an understatement. Climbing ropes are made to be particularly strechy so they dont snap tight when stopping a fall. Also they dont do well with dirt, it gets into the braid and when the rope keeps stretching it eats away from the inside.
 
Definitely not. Climbing ropes are made of nylon and stretchy, to reduce the shock load of a fall. One thing you don't want a halyard to do is stretch.

To be more accurate, 'dynamic' climbing rope is very stretchy, 'fixed' rope is not. The former has its adherents for anchor snubbers, but otherwise best to steer clear of the stuff on boats.
 
Thanks, all. Makes good sense.

I knew there had to be a catch.

Are they worse with dirt than regular halyard rope?

Thanks for the quick responses - saved me some saggy-luff embarrassment :-)
 
Aha! But maybe get a short length of 8mm for boom preventer.

I remember St T of C recommending it.

Does it sounds like I am trying to fabricate a reason to go to the GO store?

And not elastic stretchy, either, because being caught by a spring when you fall would be No Fun At All. The stretchy ones are design to deform plastically, to bring you to a relatively gentle halt, and they can only do it once.

What? They are elastic. The UIAA standard for the number of falls of Factor 1 that a climbing rope will stand is marked on the end of each length. It's up to 11 for a full weight rope.

If Go Outdoors have some cheap static rope (or semi-static, tends to mean the same thing) that might do for you. It is low stretch for abseiling and jugging up. It tends to be a bit more expensive than regular climbing rope - niche product. A caving shop would be a good place to buy it as they use vast spools of the stuff for descending potholes.
 
Very good site! Many thanks.

Although I notice that what looks like the exact same line is offered for dock lines and horse-leading.

£1.94 per m for boats and £1.84 per m for horses...

Not a big deal, but it does make you wonder. Perhaps I could ask for a 20m horse-leading line with a soft eye-splice in the end...

8mm dynamic line: "hiking"

This looks like the business.

http://www.decathlon.co.uk/hiking-rope-8mm-x-20m-id_8249406.html

So: after all that faffing about, I seem to have managed to talk myself into spending £25 for a boom-preventer guy.

Better to go sailing and practice my (non-Chinese) gybes.

Decathlon also have static 10mm lines at £17 for 10m. No longer lengths, though.

Amusingly, the 10m ropes are flagged as "suitable for drops of up to 9m".

Ouch.

(yes, I know - but it's quite funny to see them labelled like that)
