I take it you mean Jackstays Tim. We have s/s cable running along the deck both sides from the base of the forestay to the cockpit, they run close to the joint between cabin roof and deck (if that makes sense) thus are out of the way. However I understand that you can get fabric jackstays from the normal suppliers, as to what the advantage is I couldn't say apart from obviously not marking the deck, being cheaper and easier to fit.
We have a built in ring on our lifejackets that you hook onto and use stretchy harness lines purchased last year at Excel from Jimmy Greens ropes and fixings (after walking around the entire complex they proved to be cheapest.)
At the time we got the basic harness line with a single karabiner at each end, if I were to buy them again I would buy at least one with a double karabiner at one end so that you are always hooked on.
Linda loves going up forward to tend the foresail (hanked on) I think because she hates the responsibility of the helm, but she finds that on occassion she has to unhook then re hook in as she passes the shrouds so the double karabiner would negate this as she would hook into the new location before unhooking from the old.

Our jackstay is as i said attached to the foresail base ring and each is attached to a "U" bolt at the cockpit either side.
If you need pictures I will get some done. I think it is pretty easy to fit just a bit on the pricey side when you add up the cost of harness lines, fittings etc.
Thank god there is a boat show just around the corner.

Hi Tim just posted pictures of our attachment points for jackstays

I bought ready made webbing ones but wish I had exact length ones made up. The advantage of webbing is that it does not roll under your feet.

Having had both wire and webbing safety lines concur with Chille that flat webbing is less likely to trip you up and is more comfortable under foot.

Amare had quite a nice jackstay setup when I bought her. They are made of wire, with a talurite eye at each end. The u-bolts pass through the eyes - no shackles are used - and they are bolted through the deck. The forward one is about 3 foot from the bow. Strangely, one passes inside the shrouds and the other outside. I have not bothered to change them as I'm not sure which I prefer. Obviously you have to pass the correct side of the shrouds otherwise you don't get very far!

Because the wire can only rotate slightly I don't have any problem with it rotating underfoot. There are stains on the deck from the wire but I'll try to clean these off one day.

If you are thinking about jackstays you should also think about putting some attachment points in the cockpit. You need to be able to reach these easily from inside the cabin so you can clip on before coming on deck.

Make sure you have the correct type of attachment - a simple u-bolt should only be used with certain types of lifeline hook. I use the "Gibb" hooks which are ok on u-bolts.

Hope this helps.

I have fitted fabric jackstays. In fact one piece. Starting with U bolt just aft of the mainsail traveller going forward inside the shroud ,so no need to unclip at any time, and forward to the ubolt for the forestay and back the other side to a u bolt again just aft of the ms traveller. I think from memory it was 12 metres long, which leaves about 60cms for fixing at the buckle end. One disadvanage is that the life of fabric is limited - recommended replacement every two/three years, but it does not mark the deck and is flat under foot. I have had no trouble in operation. By the way I have found that Harpic Power plus to be pretty good at removing rust type stains from fibre glass.

Funny that Mike bearing in mind ours is the next boat in line to yours in production terms, our jack stays also have one inside the shrouds and one out.
As they run so close to the join between the cabin roof and deck we don't notice them there at all and seem to naturally step over them without a thought.
I agree with the idea about cockpit attachment points we have one either side of the cockpit.
I don't quite understand where the problem is with "U " bolts, as you rightly say some lines are unsuitable for U bolt attachment but I fail to see why.... anybody got any ideas?

On Aeolus we had some dreadful rust stains on the deck from where somebody had apparently used an angle grinder nearby at some stage, they came out using a preparitory cream cleaner specifically for rust stains in GRP bought from the chanderlers a bit expensive but did a brilliant job with very little effort.
I think it was called something really imaginative like "GRP stain cleaner"

I recently found a creme cleaner for uPVC windows that is excellent at cleaning GRP gelcoat. As it is not for boats it is cheap! Available from building centres.

Mike A1 says:

The problem with some hooks is that under load they can rotate around one "leg" of the u-bolt and the other leg will open the clip and allow the hook to lift off. There are numerous references to this on the web but I can't find any pictures.

If I remember rightly some lives were lost in the 1979 fastnet due to this happening.

AH I see now thanks Mike.... I know there was reference made to a problem with U bolt attachments in the instructions on my saftey harness' but it didn't explain what they were.

santalars says:

I think the main point against fabric jackstays is the limited lifetime.
Whatever you use keep in mind that when the lifeline is installed across the deck it will have to carry a significant load if you go overboard. This is not related to your weight, it's due to the very unfavourable load distribution which is almost rectangular.
In plain english this means the tensile strength of the lifeline should be approx min. 10 times your weight. It is further not recommended to prestress the lifline as the will easily double this figure again.
