John, thanks for an excellent source of great advice! I will be following this advice closely when my wife and I set off on our cruising adventures in a couple of months time. We have an Allures 44 with a new carbon mast so I am really enjoying the info on this site.
One question. The book does not say what you should do with sails and helm when the Jordan drogue is set. Maybe this is considered common knowledge? Would you lash wheel in a central position or to the side a bit or use auto helm? Sails all down or maybe a very small triangle of jib unfurled?
Thanks
Bruce
Hi Bruce,
Great question, thanks. The general wisdom is that you take all sail down, lash the helm amidships and go below.
Having said that, I would say the best answer is, if you do get caught out, to experiment to see what works best for your boat in the particular wave conditions.
Having said that, I would guess that in full storm conditions leaving any sail up may be a poor idea, particularly a furling sail. The thing is that we do know from first hand accounts that the boat’s attitude to waves will vary by a lot in the lulls and gusts the sail could be caught aback often. The resulting smashing around could easily damage the roller furling gear resulting in the whole sail unfurling—a very nasty thought.
It would be of great interest to discuss storm tactics in relation to boats with differing characteristics, for example how would the strategies discussed be adapted to a centerboarer like a Boreal or an Ovni.
Regards
Patrick
Hi Patrick,
Interesting question. First off, I think that the Jordan Series Drogue is applicable to just about any boat.
On heaving-to, Colin tells me that it is pretty much impossible to get his Ovni 435 to heave-to, although I don’t think he has tried the small drogue off the bow technique that we detail, which I would think would help.
My guess would be that the Boreal might be easier to heave-to due to the keel box.
Of course the benefit of these lifting keel boats is that with the keel up they are very seaworthy in heavy weather because they tend to slide sideways when hit by a wave instead of tripping over the keel.
Colin, any thoughts?
I read about Robin Knox Johnston using a long loop of rope as a drogue. What about a long loop of rope with Jordan cones, attached at each end to the transom corners? Half the rope would have cones facing one way and at the midpoint they would change direction. So when the loop is deployed you have all cones dragging. When it comes time to retrieve you can detach one side from the boat and you now have only half the cones dragging to pull in. Possibly a retrieval line from middle of transom to center of the loop and then detach both transom corners?
I wonder whether Jordan experimented with the loop idea? Conceptually it seems similar to using a bridal because the load would be evenly distributed on the transom corners. Has anyone heard of any loop drogue solutions?
Hi Bruce,
That’s certainly a very interesting idea. However, I’m really loath to recommend anything that makes such a substantial change to Don Jorgan’s original design for the JSD. You see Jordan did a lot of really good science on what happens in breaking waves and how best to deal with that. One of his key findings was that a drogue to be really safe across a wide range of conditions must provide drag across several wave crests. Therefore by halving the length of the JSD you would be deviating from Jordan’s design in a pretty dramatic fashion. So unless someone at Jordan’s level of expertise were able to properly model your change and determine that it would not substantially change the dynamics I would say stick with Jordan’s original design to the letter.
Hi John,
Good to see you are under sail aboard Morgan’s Cloud again. All that talk about motor boats was starting to worry me> LOL
Just came across this extensive documentation of experiences with all varieties of drogue and sea anchor devices which should be of interest for this section of your publication.

Hi Richard,
Great link, thanks. I have the old paper version of the DDD, and in fact contributed to it, but I was not aware that it was available online and in such a cool interactive way.
By the way, reading the DDD, was the major contributor to my aversion to sea anchors.
Hi Richard,
just found your post and the database you’re linking to – thanks for that great and valuable information!
And to John – just readiung this one report (http://dragdevicedb.com/drogues-on-catamarans/dc-9-catamaran-searunner) confirms everything you’ve written against parachutes. Quite a scary story – having a JSD might have saved them their boat.
Hi Ernest,
Wow, that’s a scary one.
The damming quote for sea anchors is “The sea anchor was getting rolled by the steep, confused waves, from the left, then from the right. Later, as I was watching, it got caught by two cross-seas and collapsed right before my eyes.”
Hi John. As a new comer to your very informative website, I would like to thank you. My wife and I have lived full time on boats for at least a dozen years and are constantly learning. Our present boat thanks to a local bank, is a Lagoon 52 catamaran ( a good sailing cruising “condomaran”) and are based in Australia. THE REASON FOR THIS POST: you have mentioned that you do not have much experience on cats, but I notice that you often access the wisdom from others so that we can all learn more – why not access some wisdom from some experienced and articulate world cruising catamaran sailors so that we can expand on areas that also apply perhaps in some different ways to cats. Your book such as heavy weather tactics, and reefing down wind in sail handling, would be great areas to look at from a cat point of view. Eg cats with self tacking jibs, swept back spreaders and shrouds, large sails, questionable ability to hove to… All present different issues to consider. FROM A BUSINESS PERSPECTIIVE – the number of ocean and coastal cruising catamarans are skyrocketing in numbers by comparison to monohulls – (perhaps we are getting soft) SO TAKING THIS TACT SERIOUSLY MAY EASILY DOUBLE YOUR MEMBERSHIP AND BE A GREAT SERVICE. What do you think? Cheers. Michael
Hi Michael,
Sure, sounds like a good idea. Having said that, a core value at AAC is that we only write from real-world first hand experience, none of the speculation and general blather you get in the mags or forums.
So to add multi-hull specific information we would need a new contributor who has extensive offshore experience in a multi-hull including several ocean crossings. But wait, it gets more difficult because that person also needs to be able to write well, and that’s not a common talent and one that usually takes years of practice to acquire. (We don’t have the resources to re-write submissions, as the magazines do to a good 75% of what you see between their covers.)
If someone has both of the above criteria ticked off, we would be happy to talk to them about contributing to AAC.
Appreciate that reply John and fulheartedly agree. I may know a couple potential contributors who could fit that criteria and will make enquiries. Quality, ability and extensive experience, unlike most forums, is what you are saying you may consider. Cheers. Michael
