Shouldn't we improve the safe use of all storm drogues and para-anchors regardless of brand? Whether you're willing to admit it or not, weight placement improves the function off all drag devices. The JSD just requires more weight. An average of 35 to 50 lbs.
We have no info on why Suzie's drogue broke,so lets hold off on that subject for now, eh?
As to failing cones, when some drogues are home made, one has to imagine that some might be of less quality than others. Meanwhile, Nehaj lay to hers for something like 160 hours total (I can get the exact number if required) in severe southern ocean conditions... the same conditions that Suzie and others came to grief in, and had no knockdowns, rolls or pitchpoles. Susanne reports that she used approximately 10 kg of chain as her weight, chain being easier to manipulate than a solid weight. She experienced no breakage. She did wear out quite a few cones, made from fairly heavy nylon spinnaker
cloth, and is just now busy sewing up around 100 new ones out of 6 oz Weathermax dacron, and with hemmed edges to help avoid the fraying that the originals had (only hot-knifed edges).
And I ask you again what the relevance of Navy ships use of para anchors might be for us with small craft of one sort or another? You frequently refer to such research but give no citations so we can check it for ourselves.
I have no dog in the fight, but a strong interest in real world YACHTING applicatons of drag devices. I believe that single
point devices have their place in the system, but I also think that there is pretty compelling evidence that the JSD has saved a lot of boats over the years. Your frequent disparaging comments get tiring... they would be more palatable if supported by data that we can access from original sources.
