Re: Spectre rope

It is amazing stuff. I found a short lived source selling mill ends of 1/4" Dynema for $10.00/pound. I bought a couple of good handfulls of hanks that were about 40' each. Originally it was to replace my coated ss lifelines. It did require pre loading to get the braid and my end splice tight enough for the turnbuckle to add proper tension there. I now use it for things I had never though of until this "soft steel" arrived. Towing, lifting, ridge line for my cover, any non stretch application that requires or benefits from a "tight line". Our I 28 has a 7000 lb displacement. This 1/4" line could lift it! No meat hooks! No rebound! Stuff it into your pocket! Soft shackles that weigh nothing.

Better living through chemistry for sure!

Standing rigging next, perhaps.

Something that would last forever on a boat? That's a first.

Not sure why they wouldn't be subject to cycle loading.

Re: Spectre rope

It makes more sense financially in bigger boats I think. Doing my hunter 25 refit last year I priced out the coligo vs rigging only steel, and the price of the fittings meant that the spectra rigging would have cost significantly more even though I got new turnbuckles for the steel.

However in bigger boats where a new turnbuckle might go for $600 itself, the synthetic rigging starts making sense.

I love the stuff personally, splicing it is easy but the splices really need to set, they stretch a lot until then, making precision very difficult.

Even if u don't go with all synthetic, u should consider making the back stay out of the stuff. Or making some soft shackles, those are very handy too.

As far as chafing goes, once u splice the stuff u will find that it is very hard to cut. U get maybe two or three cuts with a razor blade before it gets completely dull. I doubt genoa chafe will do much here, ESP if ur using soft shackles or bow lines to secure the sheets to the clew.

You have to factor in the cost x 2 because you'll have to replace it twice as often.
In the tropics wire has a life expectancy of 8 to 10 years max. Up north, especially in areas with much rain, 15 years plus.

Racing and trailer - sure it makes sense. Most boats, not so much.
Not true at all. About 90% of the cost of switching the first time is buying the reusable fittings. After that the rest of the cost is the line itself. So your first time it is about the same price as wire, after that it gets really cheap to replace when necessary.


Also note that 8 years is what is currently being recomended from Colligio (I believe) which is the same replacement interval for stainless fittings like turnbuckles and shackles on your standing rigging.

Re: Spectre rope

Tommays,

When I priced it out for my old Olson 30 it was within 5% the same as wire, and much less than replacing the rod I had. It is probably installation specific which way the cost falls.

Re: Spectre rope



In all the PRO jobs i have seen by the time its sized for creep the spreaders all seem to need mods ?

IN looking at the buy in for all the fittings you need at the mast and deck level it was a LOT more money than stainless on the Cal 29
