Climbing rope for halyards?

[Rivers & creeks]

I've been given some new climbing rope and I need to fit a new main halyard. The boat is a cruising 35 footer, is climbing rope too stretchy or is it ok? Thanks.

I suggest it is way too stretchy.
Use it for mooring lines and tying down stuff. (great for tying stuff onto trailers)

Yup, useless for halyards. Good for long mooring lines, especially when tied up to a quay and the tide's going up and down.

It might be fun to watch the sail lose its shape in gusts I guess.

Internally a climbing rope has the fibres laid out in parallell to make it stretchy.
Rope for halyards has the fibres pleated to make it non-stretchy and it is then pre-stretched to make it even better.

Will be good for use with a lunch anchor.

I suspect if it is tensioned it will seem fine, however what will happen is that it will suddenly go bang and break. Basically climbing rope is not designed to be kept under tension! How do I know .. I tried it a while ago ;-)

...and then it will drop down inside the mast and a massive faff will ensue.

static or dynamic

There are two basic types of climbing ropes.

Dynamic rope EN 892: dynamic elongation up to 40% 80kg mass

Static rope EN 1891: less than 5% elongation 50-150kg mass

Some high tech access lines are dyneema / vectran core for ultra low stretch.

It would be impossable to say about its use as a halyard without knowing exactly what rope it is?
