Those numbers aren't that big at all Gord. So we can rule out straight strength, nice.

Chatted with him today and he's still keen to go the Spectra so I'll make sure he tells us what happens. This bloke is a complete loony and just goes whenever he wants. Never waits for weather windows or seasons, just goes. On occasion I've been chatting with him and a few days later talking to his wife and see says things like "Oh he woke up yesterday morning and decided to go to Fiji, he left this afternoon". And the bloody bugger hasn't really been caught in a real big nasty yet. Luck of the Loonies by the looks.

This posting from Ace Sailmakers (most way down page) shows that they do make them with Spectra lines:

Thanks for the link*, Evan.

*Wherein Dave Pelissier, of Ace Sailmakers, says:
“We have recently completed many Spectra Jordan Series Drogues.
Lighter, smaller, easier to deploy, easier to recover.


Some of them:

14,000# MONOHULL:
In 5/16ths Spectra tapered to " Spectra 104 cones, Pearson Vangaurd 32.
Drogue weighed 9.25 lbs
w/o weight for end. Fit in box 16" x 14" x 7"
Nylon version would have been approx 32 lbs plus bridle, weight ..."

Wish I had know that I would have done it with Spectra. I am in the middle of one made with octoplait. The Advantage of the plait is that it can serve more than one purpose. I believe mine is 300' long total and if you need an extra anchor rode or some other such need of a stretchy line the spectra would not help out too much.

Re-use works for a rode that will be used for a standard drogue. It doesn't work for a Jordon drogue, as the cones are sewed into the line.

It is interesting to hear a number of people have or are now creating their series drogue using octoplait.

I had a long dialogue about 4 years ago with Brian Glover of Series Drogue Australia, about the use of octoplait, and they would not recommend it as the appropriate rope for the job at the time, because they had not done any trials on it.

Re: Stretchy Drogue line or not?

Another feature to remember is that the drogue itself helps to create a lee, and I would expect tha the larger diameter nylon would also play a part in this.

My choice would definitely be the nylon. As far as I know, this is either braid on braid or 3 strand. I asked sometime ago about the use of octoplait, as I prefer the characteristics of this sort of rope for these heavyweight tasks. Unfortunately nobody has done any trials with it, and there is a concern that the very factors that make octoplait such a good rope, i.e. the loose lay,, might allow the droguelets to pull out.
Snatch is a problem for all storm drogues, including the JSD. The trick is to remove as much slack in the rode as possible -- to maintain Constant Rode Tension.

The pros and cons related to storage and weight of rode are accurate. Other comments about rode not so much. If you want to learn more about the pros and cons of Dyneema/Spectra type rodes vs. Nylon for drag device deployment, then check out post #54 Drogue Failures

Would have pasted the info here, but it might be against forum rules to completely edit, copy, paste a previous post. Even if its relevant to a new thread.
