Why not send him a PM? <evanstarzinger> I'm sure he'd post you a link. He's very helpful.

We just finished 'rebuilding' our drogue using 4oz dacron with a hem on the leading edge. Likely we will never have to test it, but this should stand up much better than the original. Interestingly, we made 150 cones as recommended by Mr. Jordan for our size boat. We re-used the original rodes and found that we had 10 cones left over when we ran out of line. I think it is possible that the original kit that we got was the 140 cone kit rather than the 150 cones recommended for our boat. This may have contributed to our higher than expected speeds with the drogue deployed and we will add the additional 10 cones to another rode at the end of the drogue.

A comment regarding drogue kits. Putting a series drogue together is very labor intensive, with most of the time going towards hemming and sewing the cones, attaching the straps to the cones and attaching the cones to the rode. A kit will provide you with pre-cut cones, but the time savings is not that significant as a percentage of total time required to build the drogue. By cutting your own cones you can make them out of as heavy a material as you like and leave enough material for a hem.

This is the template I made for 5" cones with a 1/4" hem. I made a template out of doorskin and my wife cut the cones with a hot knife from Sailrite () We scalloped the hems in an effort to to reduce flapping at the leading edge. No idea whether this will be beneficial. We did add an additional cone to make up for the 1% loss in surface area.

Even with a weight at the end the JSD spends a lot of time at the surface. I would expect that even a floating trip line would eventually foul the drogue due to wave action.

In any event, I really don't think a trip line is necessary. As I mentioned previously, we were able to easily recover our drogue by hand by simply leading it to the bow and pulling it over the anchor roller. If you are able to motor at all into the wind and seas, recovery over the bow is easy.

I agrees, r.s.
Would have a second bulletproof washboard ready to go outside of the original one though...

Re: Jordan Series Drogue experience

A lot of modern catamarans seem to be design to specifically funnel breaking waves from astern directly at the patio doors. I am grateful that my Privilege 37 is not one of those.
Davits on many boats are also installed such that the dinghy is clear of water streaming under the bridge deck, but again not taking into account running before bad weather, let alone use of serial drogues. I have heavily modified my gantry and davits to raise the dinghy nearly 2 feet above the original location. I suspect that it would still be in danger in survival conditions, but it has a much better chance than before.

While few people would deliberately set out to get into such a gale at sea, having prepared for it and encountered it, the experience becomes a treasured memory to be replayed repeatedly in quiet moments.
Re-reading this excellent thread, I particularly enjoyed this post. Priceless!!

Re: Jordan Series Drogue experience

I am resurrecting this thread rather than starting a new one, as there is valuable information here. Many thanks to Mike (the OP) and all the contributors.

I am planning to make a series drogue (or buy the cones and attach these myself to HMWPE rope) and as a first step I have stared to make a list of links that may provide useful background reading.

In no particular order here they are. This may help others. If anyone had any to add, please add to the list:

A few CF threads found:

And there is this thread I opened recently to discuss the possibility of using Acera instead of dyneema:

Re: Jordan Series Drogue experience

Jeanne Socrates has put some miles (and wear & tear) on her Jordan Series Drogue. Here's a link to some photos of her damaged drogue: https://svnereida.com/blog/3744-31st...-series-drogue. She discusses it elsewhere -- I'm sure a search would find the details.

These problems seem commonly reported. The original ones (and the kits still sold online by Sailrite) were made of unhemmed nylon.

Morgan's Cloud gave a good synopsis of the problems with durability and advise heavier weight dacron and hemming. They postulate the nylon ones survived better in initial tests as the edges were cut with heat, therefore sealing the edges.

I have found two commercial operators selling the cones: Ace Sailmakers in the US and OceanBrake in the UK. The UK ones are made of 7oz dacron and hemmed. They are £2.76 each, almost half the price of the ones from Ace (no details of construction) that have been "discounted for a few days" only @ US$6.30 each (normally $7 and $6 if supplied unattached).

Ace have not responded to any of my questions regarding the line, so I am not overly impressed by them. The ones from OceanBrake seem sturdily constructed and at the price they offer I don't think it is worth making them, so I will probably purchase the cones from them and the line myself.

Re: Jordan Series Drogue experience

It seems to me that the only problem with the series drogue is the effort required to retrieve the drogue because it is always scooping water.

I think it might be possible to make a two line drogue with cones attached to one line at the forward edge and the aft edge to the other line.

Then when the aft edge is loosened the last 5 cones (or whatever works best) which are attached only to the aft line, pulls all the cones shut do the drogue can be retrieved more easily.
