Use of climbing rope onboard
NotMyRealName
I wish to purchase some "springy" climbers' rope for use on board. This
is NOT for climbing, but as an up-haul for the dagger boards.
Advice needed - is the springy rope called "dynamic"?
Would used rope be OK for this (i.e.. No longer rated for climbing) or
does it lose its springiness?
Where can I buy the right stuff by the metre? (Probably needing less
than 15 metres)
If anybody has some "end of reel" amounts and wants to sell, let me
know.
Thanks in advance

Puzzled as to why - I would have thought the stretch would make it
harder to pull the boards up.

Yes or just a climbing rope. Available around 8.5 or 9mm ("twin" or
"double" ropes, intended for use as one of a pair) or 10.5 or 11mm
("single rope")

It does lose springiness but not much. Should be fine.

That is trickier. They are normally sold pre-cut as 50m or 60m ropes.
Here are a few places to try:

http://www.peglers.co.uk/
http://www.cotswold-outdoor.com/index.jphtml?referrer=BWTD
Probably worth phoning rather than searching online catalogues as those
are likely to be the standard lengths.

Boards are difficult to raise when "under pressure" (e.g. when
preventing leeway) and will bounce up a little whenever the pressure
releases. Other Banshee sailors have used this technique.

I've known a number of people who have used second hand climbing ropes
as anchor or mooring ropes. Climbers discard their ropes early for
safety reasons, and second hand ones are cheap. However, I haven't
tried it myself.

Yes - the are each approx. 12ft 6" long, 2ft wide and 2" thick in teak.
When they were out of the boat last, 2 of us could not lift one of them.
In operation, the are lifted by a 20:1 winch, and the springy rope is to
keep pressure on them when lifting, so that they spring up a few inches
at a time when lateral pressure is removed. (This lateral pressure can
jam them slightly when sailing).

About 9mm as I recall and maybe 20meters long.
I did wonder how many ppl bought it for halyards etc as it was
unbmarked and looked like double braid/marlowbraid type.

metre, but probably only up to 9mm or so. Unfortunately there are very
few good climbing shops left. You may have to try one of the mountain
areas - some shops do have online shops too.

You must know some strange climbers - in 35 years of 'adventure'
climbing I've never known a climber discard a rope 'early' - they all
wait until they shown some serious damage or are involved in a
seriously high fall-factor fall.
I suppose it may be different if you are 'sport' climbing on bolted
routes where falling off is relatively risk free and therefore more
common.
The BMC's (British Mountaineering Council) recommendation of a few
years ago to discard your ropes after 2 years was totally ignored by
everyone in my climbing circle. I've also never heard of a climber
being injured by a rope failure unless the rope was already damaged by
abrasion or in other circumstances. The battery acid in the boot of
old mini's used to be a classic way of trashing a rope.
It's probably different in outdoor centres and on climbing walls where
the ropes get severe use and they have insurance companies to worry
about. Worth a ring round to see what's available from these sources?

I have managed to buy some new 9mm Marlow dynamic from ebay (20 metres)
- just what I needed. 9mm is just fine for this application.

I have. Someone off-route on Grooved Arete fell, rope cut over a sharp
edge and he fell 80 feet and broke his back. It was well publicised in
the climbing world at the time (around 10 years ago).
All climbers I know discard their ropes for leading purposes after a few
years. Funnily enough, I've never heard a climber use the words
"adventure climbing" either. The usual term for non-bolt protected
climbing is "trad". It slightly makes me wonder how current your
climbing experience is.

My point - perhaps not very well expressed - was that I'd never heard
of a rope failing becasue it was old. Even a new rope would have
failed in the circumstances you describe.
My climbing experience ceased around 5 years ago - has it really
changed that much?

Probably has. My last word on this subject, since this is a sailing
newsgroup.
It is widely remarked that a lot of traditional crags are becoming
overgrown throuh lack of use. Most climbers now start on indoor walls,
learn to climb hard very quickly and then move outside (maybe - a
remarkable number never climb outside at all). They don't go through an
apprenticeship of easy climbs on mountain crags. Some stick to bolted
routes, some learn trad, but in either case, frequent falls are part of
the game as part of the process of pushing your grade. The paradox, of
course, is that provided you have good protection, hard steep climbs are
fairly safe to fall off, whereas easy climbs provide a rich choice of
obstacles to hit and cause injury.
If you are taking frequent leader falls, even of low fall-factor,
keeping your rope "until it shows signs of damage" would not be very
clever. Every fall reduces the rope's elasticity. There is plenty of
evidence for that.
There was a classic exchange between on a TV climbing programme between
a middle aged trad climber, whose name I'm afraid I've forgotten, and
Airlie Anderson, who is arguably the UK's best woman climber and rarely
short of an opinion.
He: "I've never fallen off in my life".
She: "Can't really have been trying then, can you?"

Exactly! :) It's the same theory as my sig.file
