Re: series drogue or para anchor?

Hello all

A question about using Amstel. It is my understanding that 3 strand or braid is used for the JSD because it stretches, adding to the dampening effect. Amstel doesn't stretch, is this a negative? I have zero experience with the JSD and like the idea of using amstel, just curious about it's effect on the JSD functionality.

That's the beauty of the series drogue, not being a single-point drogue, it doesn't rely on stretch in the rode to achieve its 'bungee effect'...

The extreme cyclic loads on the rode of a drogue could present problems for nylon, as well. As Evans Starzinger explains:

Quote:

The primary reason such a high percentage of para-anchor rodes break in actual use (perhaps 80% of para-anchors deployed in extreme conditions have broken their rodes) is nylon’s extreme vulnerability to chafe and internal heat damage. The US Coast Guard and New England Ropes both have extensive experience with nylon failure due to internal heat generated by cyclic loading and recommend Dacron as a better alternative for a para-anchor application. Dacron, while not as stretchy as nylon, is an excellent shock absorber in these 100-600' lengths. However, from a practical standpoint, most people do not have a dedicated rode for their para-anchor and use a spare anchor rode, which is typically nylon. But we must all be aware that nylon has proven to be very vulnerable to failure in this application.

Seamanship FAQ.
Many voyagers are using Spectra for their series drogues. Steve Dashew uses Amsteel for his on WINDHORSE:

http://www.para-anchor.com/reports/dashew.smith.pdf





In addition to Amsteel being so much lighter and more easily stowed, and being FAR easier to splice than a double braid, is the utility of such a drogue being pressed into service as a shore line. As such, the fact that Amsteel floats is highly beneficial for such a purpose...

Re: series drogue or para anchor?

I read that in the '79 Fastnet race, several boats simply hove to, and the ones that did suffered no real damage. Does the JSD offer significant advantages over a simple heave to?

On many modern boats with a fin keel and spade rudder, heaving-to will tend to result in being beam on to waves. That is a invitation to a slam. Full keel boats tend to heave-to with the bow up at an angle into the waves.

Re: series drogue or para anchor?

Been thinking if I lose steering can deploy part of drogue ( comes in pieces). By adjusting bridle should have some steering.

That was a story told by Alberg about his A35:-) The story goes that the crew just took the sails down and went below and played cards. They were probably just lucky because once breaking waves reach a height of around half a boat length, ANY boat will capsize if hit broadside by a breaking wave. That would have been around 17' for an A35. Waves were reported to be MUCH higher than that. Boats in the race and commercial ships in the area reported 65 mph winds and waves from 20 to 40 feet in height.


It's interesting to read this report:http://www.blur.se/images/fastnet-race-inquiry.pdf

Re: series drogue or para anchor?

This is a great video about storm tactics, how to deploy a sea anchor in real situation and why you should use one.
You all want evidence, well here it is and the references. I have read, seen and own most of the references.
